Goal of this project

The goal of this project is to use various LLMs to help translate po files using a first already translated file.

For example, you have a .po file with msgids in English and msgstrs in French: using this file, you can ask the tool to translate the .po file into any other language. The first translation helps to disambiguate the very short sentences or parts of sentences that are usually found in .po files.

If you have an API key for the commercial LLMs, auto-po-lyglot can work with OpenAI, Anthropic Claude, Gemini and Grok. Notes:

1. Grok is implemented but not tested yet as the Grok API is not yet available in my country.
2. Claude is implemented in 2 flavors: cached (beta version on Anthropic) or non cached. The cached version uses a longer system prompt because caching only works if the system prompt is more than 1024 tokens long. The big advantage is that the cost of the cached version is much cheaper than the non-cached one. It also works with Ollama: You can run your Ollama server locally and be able to use any model that Ollama can run - depending on your hardware capabilities, of course and for free!.

Install

Prerequisite

• You must have python>=3.10 installed
• While not required, it is highly recommended that you create a python virtual env, if you don't already have one, using pipenv or conda or whatever virtual env manager you prefer. e.g.:

  conda create -n auto_po_lyglot python=3.10 && conda activate auto_po_lyglot

  or

  python -m venv ~/auto_po_lyglot && source ~/auto_po_lyglot/bin/activate

Install from PyPi

• Install the module from PyPi:

  pip install --upgrade auto_po_lyglot

Install from sources

1. Fork the repo:

   git clone https://github.com/leolivier/transpo.git auto_po_lyglot

2. cd to the auto_po_lyglot folder and install the package and its dependencies:

   cd auto_po_lyglot && pip install .

Configuration

auto_po_lyglot uses a mix of command line arguments and variables in a .env file to be as flexible as possible;

Most parameters can be given directly on the command line (if you don't use the UI version), but you can put all the parameters that don't change very often in a .env file and use the command line only to override their values when needed.

The .env file

The .env file can be created by copying the .env.example file to .env:

cp .env.example .env

Then edit the .env file to suit your needs. Specifically:

• select your default LLM and if you do not want to use the predefined default models for the selected LLM, specify the model you want to use. Variables are:
  • LLM_CLIENT: possible values are 'ollama', 'openai', 'claude' or 'claude_cached' (claude_cached is advantageous for very big system prompts ie more than 1024 tokens with sonnet3.5)
  • LLM_MODEL: default models are GPT 4o (gpt-4o-latest) for OpenAI, Claude Sonnet 3.5 (claude-3-5-sonnet-20240620) for Anthropic (claude and claude_cached), Llama3.1-8B (llama3.1:8b) for Ollama.
  • TEMPERATURE: the temperature provided to the LLM. Default is 0.2 If you choose OpenAI our Claude, you can also put in the .env file the API keys for the LLM:
  • OPENAI_API_KEY for OpenAI GPT
  • ANTHROPIC_API_KEY for Anthropic Claude
  • GEMINI_API_KEYfor Google Gemini
  • XAI_API_KEY for X Grok
• Usually, the language of the msgids and the one for the initial translation of the msgstrs will always be the same based on your own language knowledge. Especially if your native language is not English, you will probably use English as your source language and your native language as your 1st translation. Variables are:
  • ORIGINAL_LANGUAGE for the language used in msgids
  • CONTEXT_LANGUAGE for the langauge used in the 1rst translation
  • TARGET_LANGUAGES is a comma separated list of languages in which the .po file must be translated. Usually provide by the command line
• also, this is the place where you can tune the prompt for the LLM. The default ones provided work quite well, but if you can do better, please open a PR and provide your prompt with the LLM on which you tested it and attach the original and translated .po files; Variables used are SYSTEM_PROMPT and USER_PROMPT.
• LOG_LEVEL sets the log level (values are DEBUG, INFO, WARNING, ERROR, CRITICAL). This can be overriden on the command line (-v = INFO, -vv = DEBUG)

• OLLAMA_BASE_URL: the URL to access the Ollama server (if used). The default is http://localhost:11434/v1 for using a local Ollama server. If your server uses a different URL, please specify it here. There is no command line argument to this parameter.

  NOTE: if you are using the Docker Streamlit image of auto-po-lyglot, please set up Ollama properly to be able to access it from inside the container. See How do I configure Ollama server?

Only for the UI

• MODELS_PER_LLM: The list of models to show in the 'Model' select box per LMM. The format is a list of semi-colon separated strings, each string being formated like this \<llm>|[\<llm|>...]\<comma separated list of models>. The models must the technical name used in the APIs of the LLMs. Example (and default value):

  MODELS=ollama|llama3.1:8b,phi3,gemma2:2b;
  openai|gpt-4o-mini,chatgpt-4o-latest,gpt-4o,gpt-4-turbo,gpt-4-turbo-preview,gpt-4,gpt-3.5-turbo;
  claude|claude_cached|claude-3-5-sonnet-20240620,claude-3-opus-20240229,claude-3-sonnet-20240229,claude-3-haiku-20240307;
  gemini|gemini-1b,gemini-1.5b,gemini-2b,gemini-6b,gemini-12b;
  grok|grok-1b,grok-1.5b,grok-2b,grok-6b,grok-12b
  

  NOTE: The different LLM models can be set up each on separate lines.

Run it:

Running with the UI

From version 1.3.0

Running the UI from the command line

After installing auto_po_lyglot with pip, create a short Python script called auto_po_lyglot_ui.py that contains these 2 lines:

from auto_po_lyglot.po_streamlit import streamlit_main
streamlit_main()

And run streamlit run auto_po_lyglot_ui.py Then, you can go to http://localhost:8501 and provide the necessary parameters. Most of them can be initialized based on:

• the content of the .env file as described above
• the command line parameters as described below, after a '--' special param that tells streamlit that the following parameters are for auto-po-lyglot e.g.:

  streamlit run auto_po_lyglot_ui.py -- -l ollama -m phi3 -t 0.5

  Note: The -o and -p parameters are ignored.

In the UI, a help button (with a '?') explains what parameters to provide where.

Running from the Command Line

Usage: auto_po_lyglot [-h] [-p] [-l LLM] [-m MODEL] [-t TEMPERATURE] [--original_language ORIGINAL_LANGUAGE] [--context_language CONTEXT_LANGUAGE] [--target_language TARGET_LANGUAGE] [-i INPUT_PO] [-o OUTPUT_PO] [-v] [-vv]

Using Docker

From version 1.4.0

You can run auto_po_lyglot via Docker. A pre-built up-to-date image can be used at ghcr.io/leolivier/auto_po_lyglot or you can build yours.

Create Docker image

If you want to create your own Docker image, create a folder and cd to it then:

• create a small Python script called auto_po_lyglot_ui.py as described for running Streamlit from the command line:

  from auto_po_lyglot.po_streamlit import streamlit_main
  streamlit_main()

• create a file named Dockerfile that contains:

  FROM python:3.10-slim
  WORKDIR /app
  RUN apt-get update && apt-get install -y curl && rm -rf /var/lib/apt/lists/*
  RUN pip install auto-po-lyglot
  COPY ./auto_po_lyglot_ui.py .
  EXPOSE 8501
  HEALTHCHECK CMD curl --fail http://localhost:8501/_stcore/health
  ENTRYPOINT ["streamlit", "run", "auto_po_lyglot_ui.py", "--server.port=8501", "--server.address=0.0.0.0"]

  Then run docker build -t auto_po_lyglot . to create your image locally

Running the docker image

if you built the image yourself, run:

docker run -p 8501:8501 -v ./.env:/app/.env --name auto_po_lyglot auto_po_lyglot:latest

If you want to use the pre-built image, run:

docker run -p 8501:8501 -v ./.env:/app/.env --name auto_po_lyglot ghcr.io/leolivier/auto_po_lyglot:latest
