gpt-translate 3.1.0

A tool to translate markdown files using GPT-4

gpt_translate: Translating MD files with GPT-4

This is a tool to translate Markdown files without breaking the structure of the document. It is powered by OpenAI models and has multiple parsing and formatting options. The provided default example is the one we use to translate our documentation website docs.wandb.ai to japanese and korean.

You can click here to see the output of the translation on the screenshot above.

Installation

We have a stable version on PyPi, so you can install it with pip:

$ pip install gpt-translate

or to get latest version from the repo:

$ cd gpt_translate
$ pip install .

Export your OpenAI API key:

export OPENAI_API_KEY=aa-proj-bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Usage

The library provides a set of commands that you can access as CLI. All the commands start by gpt_translate.:

• gpt_translate.file: Translate a single file
• gpt_translate.folder: Translate a folder recursively
• gpt_translate.files: Translate a list of files, accepts .txt list of files as input.

We use GPT4 by default. You can change this on configs/config.yaml. The dafault values are:

# Logs:
debug: false  # Debug mode
weave_project: "gpt-translate"  # Weave project
silence_openai: true  # Silence OpenAI logger

# Translation:
language: "ja"  # Language to translate to
config_folder: "./configs"  # Config folder, where the prompts and dictionaries are
replace: true  # Replace existing file
remove_comments: true  # Remove comments
do_evaluation: true  # Do evaluation
do_translate_header_description: true  # Translate the header description
max_openai_concurrent_calls: 7  # Max number of concurrent calls to OpenAI

# Files:
input_file: "docs/intro.md"  # File to translate
out_file: " intro_ja.md"  # File to save the translated file to
input_folder: null  # Folder to translate
out_folder: null  # Folder to save the translated files to
limit: null  # Limit number of files to translate

# Model:
model: "gpt-4o"
temperature: 1.0
max_tokens: 4096

You can override the arguments at runtime or by creating another config.yaml file. You can also use the --config_path flag to specify a different config file.

• The --config_folder argument is where the prompts and dictionaries are located, the actual config.yaml could be located somewhere else. Maybe I need a better naming here =P.

• You can add new languages by providing the language translation dictionaries in configs/language_dicts

Examples

1. To translate a single file:

$ gpt_translate.file \
  --input_file README.md \
  --out_file README_es_.md \
  --language es
  --config_folder ./configs

2. Translate a list of files from list.txt:

$ gpt_translate.files \
  --input_file list.txt \
  --input_folder docs \ 
  --out_folder docs_ja \
  --language ja
  --config_folder ./configs

Note here that we need to pass and input and output folder. This is because we will be using the input folder to get the relative path and create the same folder structure in the output folder. This is tipically what you want for documentation websites that are organized in folders like ./docs.

3. Translate a full folder recursively:

$ gpt_translate.folder \
  --input_folder docs \
  --out_folder docs_ja \
  --language ja
  --config_folder ./configs

If you don't know what to do, you can always do --help on any of the commands:

$ gpt_translate.* --help

Validation

The library performs an evaluation of the quality of the translation if --do_evaluation is set to true. You can modify the output of the LLM evaluation by changing the configs/evaluation_prompt.txt.

Play with this prompt and maybe you can find better ways to evaluate the quality of the translation.

Weave Tracing

The library does a lot! keeping track of every piece of interaction is necessary. We added W&B Weave support to trace every call to the model and underlying processing bits.

You can pass a project name to the CLI to trace the calls:

$ gpt_translate.folder \
  --input_folder docs \
  --output_folder docs_ja \
  --language ja \
  --weave_project gpt-translate
  --config_folder ./configs

Github Action

We supply an action.yml file to use this library in a Github Action. It is not much tested, but it should work.

• You will need to setup your Weights & Biases API key as a secret in your Github repository as WANDB_API_KEY.

An example workflow is shown in https://github.com/tcapelle/dummy_docs and the corresponding workflow file

TroubleShooting

If you have any issue, you can always pass the --debug flag to get more information about what is happening:

$ gpt_translate.folder ... --debug

this will get you a very verbose output (calls to models, inputs and outputs, etc.)
