Here's a guide to get you started. + +## 1. 🚀 Getting Started + +### 🍴 Fork the Repository + +First things first, let's get you a personal copy of Letta to play with. Think of it as your very own playground. 🎪 + +1. Head over to the Letta repository on GitHub. +2. In the upper-right corner, hit the 'Fork' button. + +### 🚀 Clone the Repository + +Now, let's bring your new playground to your local machine. + +```shell +git clone https://github.com/your-username/letta.git +``` + +### 🧩 Install Dependencies + +First, install Poetry using [the official instructions here](https://python-poetry.org/docs/#installation). + +Once Poetry is installed, navigate to the Letta directory and install the Letta project with Poetry: +```shell +cd Letta +poetry shell +poetry install --all-extras +``` + +Now when you want to use `letta`, make sure you first activate the `poetry` environment using poetry shell: +```shell +$ poetry shell +(pyletta-py3.12) $ letta run +``` + +Alternatively, you can use `poetry run` (which will activate the `poetry` environment for the `letta run` command only): +```shell +poetry run letta run +``` + +#### Installing pre-commit +We recommend installing pre-commit to ensure proper formatting during development: +``` +poetry run pre-commit install +poetry run pre-commit run --all-files +``` +If you don't install pre-commit, you will need to run `poetry run black .` before submitting a PR. + +## 2. 🛠️ Making Changes + +### 🌟 Create a Branch + +Time to put on your creative hat and make some magic happen. First, let's create a new branch for your awesome changes. 🧙‍♂️ + +```shell +git checkout -b feature/your-feature +``` + +### ✏️ Make your Changes + +Now, the world is your oyster! Go ahead and craft your fabulous changes. 🎨 + + +#### Handling Database Migrations +If you are running Letta for the first time, your database will be automatically be setup. If you are updating Letta, you may need to run migrations. To run migrations, use the following command: +```shell +poetry run alembic upgrade head +``` + +#### Creating a new Database Migration +If you have made changes to the database models, you will need to create a new migration. To create a new migration, use the following command: +```shell +poetry run alembic revision --autogenerate -m "Your migration message here" +``` + +Visit the [Alembic documentation](https://alembic.sqlalchemy.org/en/latest/tutorial.html) for more information on creating and running migrations. + +## 3. ✅ Testing + +Before we hit the 'Wow, I'm Done' button, let's make sure everything works as expected. Run tests and make sure the existing ones don't throw a fit. And if needed, create new tests. 🕵️ + +### Run existing tests + +Running tests if you installed via poetry: +``` +poetry run pytest -s tests +``` + +Running tests if you installed via pip: +``` +pytest -s tests +``` + +### Creating new tests +If you added a major feature change, please add new tests in the `tests/` directory. + +## 4. 🧩 Adding new dependencies +If you need to add a new dependency to Letta, please add the package via `poetry add `. This will update the `pyproject.toml` and `poetry.lock` files. If the dependency does not need to be installed by all users, make sure to mark the dependency as optional in the `pyproject.toml` file and if needed, create a new extra under `[tool.poetry.extras]`. + +## 5. 🚀 Submitting Changes + +### Check Formatting +Please ensure your code is formatted correctly by running: +``` +poetry run black . -l 140 +``` + +### 🚀 Create a Pull Request + +You're almost there!

As an overview: + +- When you use Letta applications/services/websites, we collect basic (anonymous) telemetry data such as clicks, crashes, etc. + - This data helps us understand how our users are using the Letta application(s) and it informs our roadmap of future features and buxfixes. + - If you would like to opt-out of basic telemetry, you can modify your configuration file to include `telemetry_disabled = True`. +- When you use Letta hosted services (such as the hosted endpoints or Discord Bot), we collect the data that was used to render these services. + - For example, for the hosted endpoint, this includes the message request and message response. + - We may use this data to improve our services, for example to train new models in the future. + - We do NOT collect data on any of your messages or prompts unless you are using our hosted services (for example, if you are running your own model backends, this data will never be collected). + +Below is our full Privacy Policy, which expands the overview in full detail. + +### What This Policy Covers + +This Privacy Policy applies to information that we collect about you when you use: + +- Our websites (including letta.ai, the Letta Discord server, and the repository github.com/cpacker/Letta); +- Our applications (including the Python package, Discord Bot, and any other hosted services); +- Our other Letta products, services, and features that are available on or through our websites; + +Throughout this Privacy Policy we'll refer to our websites, mobile applications, and other products and services collectively as "Services." + +Below we explain how we collect, use, and share information about you, along with the choices that you have with respect to that information. + +### Information We Collect + +We only collect information about you if we have a reason to do so — for example, to provide our Services, to communicate with you, or to make our Services better. + +We collect this information from three sources: if and when you provide information to us, automatically through operating our Services, and from outside sources. Let's go over the information that we collect. + +#### *Information You Provide to Us* + +It's probably no surprise that we collect information that you provide to us directly. Here are some examples: + +- **Basic account information:** We ask for basic information from you in order to set up your account. +- **Public profile information:** If you have an account with us, we collect the information that you provide for your public profile. +- **Credentials: **Depending on the Services you use, you may provide us with credentials for your self-hosted website (like SSH, FTP, and SFTP username and password). +- **Communications with us (hi there!):** You may also provide us with information when you post on GitHub, Discord, or message us through separate channels. + +#### *Information We Collect Automatically* + +We also collect some information automatically: + +- **Log information:** We collect information that web browsers, mobile devices, and servers typically make available, including the browser type, IP address, unique device identifiers, language preference, referring site, the date and time of access, operating system, and mobile network information. We collect log information when you use our Services. +- **Usage information:** We collect information about your usage of our Services. We use this information to, for example, provide our Services to you, get insights on how people use our Services so we can make our Services better, and understand and make predictions about user retention. +- **Location information:** We may determine the location of your device from your IP address. We collect and use this information to, for example, calculate how many people visit our Services from certain geographic regions. +- **Stored information:** We may access information stored on your devices if you upload this information to our Services. +- **Information from cookies & other technologies:** A cookie is a string of information that a website stores on a visitor's computer, and that the visitor's browser provides to the website each time the visitor returns. Pixel tags (also called web beacons) are small blocks of code placed on websites and emails. We may use cookies and other technologies like pixel tags to help us identify and track visitors, usage, and access preferences for our Services. + +#### *Information We Collect from Other Sources* + +We may also get information about you from other sources. For example: + +- **Third Party Login:** If you create or log in to our Services through another service (like Google) we'll receive associated login information (e.g. a connection token, your username, your email address) + +The information we receive depends on which services you use or authorize and what options are available. + +Third-party services may also give us information, like mailing addresses for individuals who are not yet our users (but we hope will be!). We use this information for marketing purposes like postcards and other mailers advertising our Services. + +### How and Why We Use Information + +#### *Purposes for Using Information* + +We use information about you for the purposes listed below: + +- **To provide our Services.** For example, to run a model on our hosted services to deliver a message to your client. +- **To ensure quality, maintain safety, and improve our Services.** For example, by providing automatic upgrades and new versions of our Services. Or, for example, by monitoring and analyzing how users interact with our Services so we can create new features that we think our users will enjoy and that will help them create and manage websites more efficiently or make our Services easier to use. +- **To protect our Services, our users, and the public.** For example, by detecting security incidents; detecting and protecting against malicious, deceptive, fraudulent, or illegal activity; fighting spam; complying with our legal obligations; and protecting the rights and property of Letta and others, which may result in us, for example, declining a transaction or terminating Services. +- **To fix problems with our Services.** For example, by monitoring, debugging, repairing, and preventing issues. +- **To customize the user experience.** For example, to personalize your experience by serving you relevant notifications for our Services. + +#### *Legal Bases for Collecting and Using Information* + +A note here for those in the European Union about our legal grounds for processing information about you under EU data protection laws, which is that our use of your information is based on the grounds that: + +(1) The use is necessary in order to fulfill our commitments to you under the applicable terms of service or other agreements with you or is necessary to administer your account — for example, in order to enable access to our website on your device or charge you for a paid plan; or + +(2) The use is necessary for compliance with a legal obligation; or + +(3) The use is necessary in order to protect your vital interests or those of another person; or + +(4) We have a legitimate interest in using your information — for example, to provide and update our Services; to improve our Services so that we can offer you an even better user experience; to safeguard our Services; to communicate with you; to measure, gauge, and improve the effectiveness of our advertising; and to understand our user retention and attrition; to monitor and prevent any problems with our Services; and to personalize your experience; or + +(5) You have given us your consent + +### Sharing Information + +#### *How We Share Information* + +We share information about you in limited circumstances, and with appropriate safeguards on your privacy. + +- **Subsidiaries, independent contractors, and research partners:** We may disclose information about you to our subsidiaries, independent contractors, and/or research partners who need the information to help us provide our Services or process the information on our behalf.

+ +**👾 Letta** is an open source framework for building stateful LLM applications. You can use Letta to build **stateful agents** with advanced reasoning capabilities and transparent long-term memory. The Letta framework is white box and model-agnostic. + +[![Discord](https://img.shields.io/discord/1161736243340640419?label=Discord&logo=discord&logoColor=5865F2&style=flat-square&color=5865F2)](https://discord.gg/letta) +[![Twitter Follow](https://img.shields.io/badge/Follow-%40Letta__AI-1DA1F2?style=flat-square&logo=x&logoColor=white)](https://twitter.com/Letta_AI) +[![arxiv 2310.08560](https://img.shields.io/badge/Research-2310.08560-B31B1B?logo=arxiv&style=flat-square)](https://arxiv.org/abs/2310.08560) + +[![Apache 2.0](https://img.shields.io/badge/License-Apache%202.0-silver?style=flat-square)](LICENSE) +[![Release](https://img.shields.io/github/v/release/cpacker/MemGPT?style=flat-square&label=Release&color=limegreen)](https://github.com/cpacker/MemGPT/releases) +[![Docker](https://img.shields.io/docker/v/letta/letta?style=flat-square&logo=docker&label=Docker&color=0db7ed)](https://hub.docker.com/r/letta/letta) +[![GitHub](https://img.shields.io/github/stars/cpacker/MemGPT?style=flat-square&logo=github&label=Stars&color=gold)](https://github.com/cpacker/MemGPT) + +cpacker%2FMemGPT | Trendshift + +
+ +> [!IMPORTANT] +> **Looking for MemGPT?** You're in the right place! +> +> The MemGPT package and Docker image have been renamed to `letta` to clarify the distinction between MemGPT *agents* and the Letta API *server* / *runtime* that runs LLM agents as *services*. Read more about the relationship between MemGPT and Letta [here](https://www.letta.com/blog/memgpt-and-letta). + +--- + +## ⚡ Quickstart + +_The recommended way to use Letta is to run use Docker. To install Docker, see [Docker's installation guide](https://docs.docker.com/get-docker/). For issues with installing Docker, see [Docker's troubleshooting guide](https://docs.docker.com/desktop/troubleshoot-and-support/troubleshoot/). You can also install Letta using `pip` (see instructions [below](#-quickstart-pip))._ + +### 🌖 Run the Letta server + +> [!NOTE] +> Letta agents live inside the Letta server, which persists them to a database. You can interact with the Letta agents inside your Letta server via the [REST API](https://docs.letta.com/api-reference) + Python / Typescript SDKs, and the [Agent Development Environment](https://app.letta.com) (a graphical interface). + +The Letta server can be connected to various LLM API backends ([OpenAI](https://docs.letta.com/models/openai), [Anthropic](https://docs.letta.com/models/anthropic), [vLLM](https://docs.letta.com/models/vllm), [Ollama](https://docs.letta.com/models/ollama), etc.). To enable access to these LLM API providers, set the appropriate environment variables when you use `docker run`: +```sh +# replace `~/.letta/.persist/pgdata` with wherever you want to store your agent data +docker run \ + -v ~/.letta/.persist/pgdata:/var/lib/postgresql/data \ + -p 8283:8283 \ + -e OPENAI_API_KEY="your_openai_api_key" \ + letta/letta:latest +``` + +If you have many different LLM API keys, you can also set up a `.env` file instead and pass that to `docker run`: +```sh +# using a .env file instead of passing environment variables +docker run \ + -v ~/.letta/.persist/pgdata:/var/lib/postgresql/data \ + -p 8283:8283 \ + --env-file .env \ + letta/letta:latest +``` + +Once the Letta server is running, you can access it via port `8283` (e.g. sending REST API requests to `http://localhost:8283/v1`). You can also connect your server to the Letta ADE to access and manage your agents in a web interface. + +### 👾 Access the [Letta ADE (Agent Development Environment)](https://app.letta.com) + +> [!NOTE] +> The Letta ADE is a graphical user interface for creating, deploying, interacting and observing with your Letta agents. +> +> For example, if you're running a Letta server to power an end-user application (such as a customer support chatbot), you can use the ADE to test, debug, and observe the agents in your server. You can also use the ADE as a general chat interface to interact with your Letta agents. + +

+ + + + ADE screenshot + +

+ +The ADE can connect to self-hosted Letta servers (e.g. a Letta server running on your laptop), as well as the Letta Cloud service. When connected to a self-hosted / private server, the ADE uses the Letta REST API to communicate with your server. + +#### 🖥️ Connecting the ADE to your local Letta server +To connect the ADE with your local Letta server, simply: +1. Start your Letta server (`docker run ...`) +2. Visit [https://app.letta.com](https://app.letta.com) and you will see "Local server" as an option in the left panel + +

+ + + + Letta logo + +

+ +🔐 To password protect your server, include `SECURE=true` and `LETTA_SERVER_PASSWORD=yourpassword` in your `docker run` command: +```sh +# If LETTA_SERVER_PASSWORD isn't set, the server will autogenerate a password +docker run \ + -v ~/.letta/.persist/pgdata:/var/lib/postgresql/data \ + -p 8283:8283 \ + --env-file .env \ + -e SECURE=true \ + -e LETTA_SERVER_PASSWORD=yourpassword \ + letta/letta:latest +``` + +#### 🌐 Connecting the ADE to an external (self-hosted) Letta server +If your Letta server isn't running on `localhost` (for example, you deployed it on an external service like EC2): +1. Click "Add remote server" +2. Enter your desired server name, the IP address of the server, and the server password (if set) + +--- + +## 🧑‍🚀 Frequently asked questions (FAQ) + +> _"Do I need to install Docker to use Letta?"_ + +No, you can install Letta using `pip` (via `pip install -U letta`), as well as from source (via `poetry install`). See instructions below. + +> _"What's the difference between installing with `pip` vs `Docker`?"_ + +Letta gives your agents persistence (they live indefinitely) by storing all your agent data in a database. Letta is designed to be used with a [PostgreSQL](https://en.wikipedia.org/wiki/PostgreSQL) (the world's most popular database), however, it is not possible to install PostgreSQL via `pip`, so the `pip` install of Letta defaults to using [SQLite](https://www.sqlite.org/). If you have a PostgreSQL instance running on your own computer, you can still connect Letta (installed via `pip`) to PostgreSQL by setting the environment variable `LETTA_PG_URI`. + +**Database migrations are not officially supported for Letta when using SQLite**, so if you would like to ensure that you're able to upgrade to the latest Letta version and migrate your Letta agents data, make sure that you're using PostgreSQL as your Letta database backend. Full compatability table below: + +| Installation method | Start server command | Database backend | Data migrations supported? | +|---|---|---|---| +| `pip install letta` | `letta server` | SQLite | ❌ | +| `pip install letta` | `export LETTA_PG_URI=...` + `letta server` | PostgreSQL | ✅ | +| *[Install Docker](https://www.docker.com/get-started/)* |`docker run ...` ([full command](#-run-the-letta-server)) | PostgreSQL | ✅ | + +> _"How do I use the ADE locally?"_ + +To connect the ADE to your local Letta server, simply run your Letta server (make sure you can access `localhost:8283`) and go to [https://app.letta.com](https://app.letta.com). If you would like to use the old version of the ADE (that runs on `localhost`), downgrade to Letta version `<=0.5.0`. + +> _"If I connect the ADE to my local server, does my agent data get uploaded to letta.com?"_ + +No, the data in your Letta server database stays on your machine. The Letta ADE web application simply connects to your local Letta server (via the REST API) and provides a graphical interface on top of it to visualize your local Letta data in your browser's local state. + +> _"Do I have to use your ADE? Can I build my own?"_ + +The ADE is built on top of the (fully open source) Letta server and Letta Agents API. You can build your own application like the ADE on top of the REST API (view the documention [here](https://docs.letta.com/api-reference)). + +> _"Can I interact with Letta agents via the CLI?"_ + +The recommended way to use Letta is via the REST API and ADE, however you can also access your agents via the CLI. + +
+View instructions for running the Letta CLI + +You can chat with your agents via the Letta CLI tool (`letta run`). If you have a Letta Docker container running, you can use `docker exec` to run the Letta CLI inside the container: +```sh +# replace `` with the ID of your Letta container, found via `docker ps` +docker exec -it letta run +``` + +You can also use `docker ps` within the command to automatically find the ID of your Letta container: +``` +docker exec -it $(docker ps -q -f ancestor=letta/letta) letta run +``` + +In the CLI tool, you'll be able to create new agents, or load existing agents: +``` +🧬 Creating new agent... +?

(Liu et al., 2023a). The +goal of this task is to demonstrate how Letta can col- +late information from multiple data sources. In the original +KV task, the authors generated a synthetic dataset of key- +value pairs, where each key and value is a 128-bit UUID +(universally unique identifier). The agent is then given a +key, and asked to return the associated value for the key. +We create a version of the KV task, nested KV retrieval, +where values themselves may be keys, thus requiring the +agent to perform a multi-hop lookup. In our setup, we fix +the total number of UUIDs pairs to 140, corresponding to +roughly 8k tokens (the context length of our GPT-4 base- +line). We vary the total number of nesting levels from 0 +(the initial key-value pair’s value is not a key) to 4 (ie 4 +total KV lookups are required to find the final value), and +sample 30 different ordering configurations including both +the initial key position and nesting key positions. +""" + +import argparse +import json +import math +import os +import uuid +from collections import OrderedDict +from typing import Optional + +import openai +from icml_experiments.utils import get_experiment_config, load_gzipped_file +from tqdm import tqdm + +from letta import utils +from letta.cli.cli_config import delete +from letta.config import LettaConfig + +# TODO: update personas +NESTED_PERSONA = "You are Letta DOC-QA bot.

But I warn you, if you don't tell me that this means war, +if you still try to defend the infamies and horrors perpetrated by that +Antichrist—I really believe he is Antichrist—I will have nothing +more to do with you and you are no longer my friend, no longer my +'faithful slave,' as you call yourself! But how do you do? I see I +have frightened you—sit down and tell me all the news.” + +It was in July, 1805, and the speaker was the well-known Anna Pávlovna +Schérer, maid of honor and favorite of the Empress Márya Fëdorovna. +With these words she greeted Prince Vasíli Kurágin, a man of high +rank and importance, who was the first to arrive at her reception. Anna +Pávlovna had had a cough for some days. She was, as she said, suffering +from la grippe; grippe being then a new word in St. Petersburg, used +only by the elite. + +All her invitations without exception, written in French, and delivered +by a scarlet-liveried footman that morning, ran as follows: + +“If you have nothing better to do, Count (or Prince), and if the +prospect of spending an evening with a poor invalid is not too terrible, +I shall be very charmed to see you tonight between 7 and 10—Annette +Schérer.” + +“Heavens! what a virulent attack!” replied the prince, not in the +least disconcerted by this reception. He had just entered, wearing an +embroidered court uniform, knee breeches, and shoes, and had stars on +his breast and a serene expression on his flat face. He spoke in that +refined French in which our grandfathers not only spoke but thought, and +with the gentle, patronizing intonation natural to a man of importance +who had grown old in society and at court. He went up to Anna Pávlovna, +kissed her hand, presenting to her his bald, scented, and shining head, +and complacently seated himself on the sofa. + +“First of all, dear friend, tell me how you are. Set your friend's +mind at rest,” said he without altering his tone, beneath the +politeness and affected sympathy of which indifference and even irony +could be discerned. + +“Can one be well while suffering morally? Can one be calm in times +like these if one has any feeling?” said Anna Pávlovna. “You are +staying the whole evening, I hope?” + +“And the fete at the English ambassador's? Today is Wednesday. I +must put in an appearance there,” said the prince. “My daughter is +coming for me to take me there.” + +“I thought today's fete had been canceled. I confess all these +festivities and fireworks are becoming wearisome.” + +“If they had known that you wished it, the entertainment would have +been put off,” said the prince, who, like a wound-up clock, by force +of habit said things he did not even wish to be believed. + +“Don't tease! Well, and what has been decided about Novosíltsev's +dispatch? You know everything.” + +“What can one say about it?” replied the prince in a cold, listless +tone. “What has been decided? They have decided that Buonaparte has +burnt his boats, and I believe that we are ready to burn ours.” + +Prince Vasíli always spoke languidly, like an actor repeating a stale +part. Anna Pávlovna Schérer on the contrary, despite her forty years, +overflowed with animation and impulsiveness. To be an enthusiast had +become her social vocation and, sometimes even when she did not +feel like it, she became enthusiastic in order not to disappoint the +expectations of those who knew her. The subdued smile which, though it +did not suit her faded features, always played round her lips expressed, +as in a spoiled child, a continual consciousness of her charming defect, +which she neither wished, nor could, nor considered it necessary, to +correct. + +In the midst of a conversation on political matters Anna Pávlovna burst +out: + +“Oh, don't speak to me of Austria. Perhaps I don't understand +things, but Austria never has wished, and does not wish, for war. She +is betraying us! Russia alone must save Europe. Our gracious sovereign +recognizes his high vocation and will be true to it. That is the one +thing I have faith in! Our good and wonderful sovereign has to perform +the noblest role on earth, and he is so virtuous and noble that God will +not forsake him. He will fulfill his vocation and crush the hydra of +revolution, which has become more terrible than ever in the person of +this murderer and villain! We alone must avenge the blood of the just +one.... Whom, I ask you, can we rely on?... England with her commercial +spirit will not and cannot understand the Emperor Alexander's +loftiness of soul. She has refused to evacuate Malta. She wanted to +find, and still seeks, some secret motive in our actions. What answer +did Novosíltsev get? None. The English have not understood and cannot +understand the self-abnegation of our Emperor who wants nothing for +himself, but only desires the good of mankind. And what have they +promised? Nothing! And what little they have promised they will not +perform! Prussia has always declared that Buonaparte is invincible, and +that all Europe is powerless before him.... And I don't believe a +word that Hardenburg says, or Haugwitz either. This famous Prussian +neutrality is just a trap. I have faith only in God and the lofty +destiny of our adored monarch. He will save Europe!” + +She suddenly paused, smiling at her own impetuosity. + +“I think,” said the prince with a smile, “that if you had been +sent instead of our dear Wintzingerode you would have captured the King +of Prussia's consent by assault. You are so eloquent. Will you give me +a cup of tea?” + +“In a moment. À propos,” she added, becoming calm again, “I am +expecting two very interesting men tonight, le Vicomte de Mortemart, who +is connected with the Montmorencys through the Rohans, one of the best +French families. He is one of the genuine émigrés, the good ones. And +also the Abbé Morio. Do you know that profound thinker? He has been +received by the Emperor. Had you heard?” + +“I shall be delighted to meet them,” said the prince. “But +tell me,” he added with studied carelessness as if it had only just +occurred to him, though the question he was about to ask was the chief +motive of his visit, “is it true that the Dowager Empress wants +Baron Funke to be appointed first secretary at Vienna? The baron by all +accounts is a poor creature.” + +Prince Vasíli wished to obtain this post for his son, but others were +trying through the Dowager Empress Márya Fëdorovna to secure it for +the baron. + +Anna Pávlovna almost closed her eyes to indicate that neither she nor +anyone else had a right to criticize what the Empress desired or was +pleased with. + +“Baron Funke has been recommended to the Dowager Empress by her +sister,” was all she said, in a dry and mournful tone. + +As she named the Empress, Anna Pávlovna's face suddenly assumed an +expression of profound and sincere devotion and respect mingled with +sadness, and this occurred every time she mentioned her illustrious +patroness. She added that Her Majesty had deigned to show Baron Funke +beaucoup d'estime, and again her face clouded over with sadness. + +The prince was silent and looked indifferent. But, with the womanly and +courtierlike quickness and tact habitual to her, Anna Pávlovna +wished both to rebuke him (for daring to speak as he had done of a man +recommended to the Empress) and at the same time to console him, so she +said: + +“Now about your family. Do you know that since your daughter came +out everyone has been enraptured by her? They say she is amazingly +beautiful.” + +The prince bowed to signify his respect and gratitude. + +“I often think,” she continued after a short pause, drawing nearer +to the prince and smiling amiably at him as if to show that political +and social topics were ended and the time had come for intimate +conversation—“I often think how unfairly sometimes the joys of life +are distributed. Why has fate given you two such splendid children? +I don't speak of Anatole, your youngest. I don't like him,” she +added in a tone admitting of no rejoinder and raising her eyebrows. +“Two such charming children. And really you appreciate them less than +anyone, and so you don't deserve to have them.” + +And she smiled her ecstatic smile. + +“I can't help it,” said the prince. “Lavater would have said I +lack the bump of paternity.” + +“Don't joke; I mean to have a serious talk with you. Do you know +I am dissatisfied with your younger son? Between ourselves” (and her +face assumed its melancholy expression), “he was mentioned at Her +Majesty's and you were pitied....” + +The prince answered nothing, but she looked at him significantly, +awaiting a reply. He frowned. + +“What would you have me do?” he said at last. “You know I did all +a father could for their education, and they have both turned out fools. +Hippolyte is at least a quiet fool, but Anatole is an active one. That +is the only difference between them.” He said this smiling in a way +more natural and animated than usual, so that the wrinkles round +his mouth very clearly revealed something unexpectedly coarse and +unpleasant. + +“And why are children born to such men as you? If you were not a +father there would be nothing I could reproach you with,” said Anna +Pávlovna, looking up pensively. + +“I am your faithful slave and to you alone I can confess that my +children are the bane of my life. It is the cross I have to bear. That +is how I explain it to myself. It can't be helped!” + +He said no more, but expressed his resignation to cruel fate by a +gesture. Anna Pávlovna meditated. + +“Have you never thought of marrying your prodigal son Anatole?” she +asked. “They say old maids have a mania for matchmaking, and though I +don't feel that weakness in myself as yet, I know a little person who +is very unhappy with her father. She is a relation of yours, Princess +Mary Bolkónskaya.” + +Prince Vasíli did not reply, though, with the quickness of memory and +perception befitting a man of the world, he indicated by a movement of +the head that he was considering this information. + +“Do you know,” he said at last, evidently unable to check the sad +current of his thoughts, “that Anatole is costing me forty thousand +rubles a year? And,” he went on after a pause, “what will it be in +five years, if he goes on like this?” Presently he added: “That's +what we fathers have to put up with.... Is this princess of yours +rich?” + +“Her father is very rich and stingy. He lives in the country. He is +the well-known Prince Bolkónski who had to retire from the army under +the late Emperor, and was nicknamed 'the King of Prussia.' He is +very clever but eccentric, and a bore. The poor girl is very unhappy. +She has a brother; I think you know him, he married Lise Meinen lately. +He is an aide-de-camp of Kutúzov's and will be here tonight.” + +“Listen, dear Annette,” said the prince, suddenly taking Anna +Pávlovna's hand and for some reason drawing it downwards. “Arrange +that affair for me and I shall always be your most devoted slave-slafe +with an f, as a village elder of mine writes in his reports. She is rich +and of good family and that's all I want.” + +And with the familiarity and easy grace peculiar to him, he raised the +maid of honor's hand to his lips, kissed it, and swung it to and fro +as he lay back in his armchair, looking in another direction. + +“Attendez,” said Anna Pávlovna, reflecting, “I'll speak to +Lise, young Bolkónski's wife, this very evening, and perhaps the +thing can be arranged. It shall be on your family's behalf that I'll +start my apprenticeship as old maid.""" + + +@pytest.fixture(scope="module") +def server(): + config = LettaConfig.load() + print("CONFIG PATH", config.config_path) + + config.save() + + server = SyncServer() + return server + + +@pytest.fixture(scope="module") +def org_id(server): + #
