jupyter-translate 2024.0

A Python script for translating Jupyter notebook files.

Jupyter Translate: a Python script for translating Jupyter notebook files

[version 2024]

This script was created as a general-purpose translator for Jupyter notebooks, translating across different languages (the default source language is English). Install it with:

pip install jupyter_translate

or

pip install .

After installed, you can use it but running the following command in the terminal:

jupyter_translate test_Notebook_en.ipynb --target pt

A new file named test_Notebook_en_pt.ipynb will be created (or the code of the language you decided to use). There is also a script for automatically translating all .ipynb files in a folder and its subfolders. Additionally, you can use a version of the script that converts from/to any language, like:

jupyter_translate test_Notebook_pt.ipynb --source pt --target en

The program translates markdown content, comments in code cells, and messages formatted in print(f" ... ").

Translator Options:

By default, jupyter-translate uses googletrans on its backend. However, you can specify a different translator using the --translator option. Here’s how to use it:

python jupyter_translate.py test_Notebook_en.ipynb --target pt --translator='mymemory'

Currently supported translators are:

• google (default)
• mymemory

**Caution:** If you are using `mymemory` as backend translator, the language codes are different. The script will show you the codes. Make sure to specify the correct `--source` and `--target` language codes supported by the selected translator. The --language option can be set to any of the following (codes from default `googletrans`:

Other options:

--delay:
The delay in seconds between retries in case of connection issues. The default is 10 seconds. Adjusting this can help if you're facing connectivity issues, especially behind firewalls.

python jupyter_translate.py my_notebook.ipynb --target es --delay=15

--rename:
If specified, this option will rename the original notebook file after the translation is complete. This can be useful if you want to keep the translated version as the primary file.

python jupyter_translate.py my_notebook.ipynb --target es --rename

--print:
Use this option if you want to print the translations directly to the console as they happen.

python jupyter_translate.py my_notebook.ipynb --target es --print

Implementation notes:

To set up a working Conda environment to use this tool, you must install a newer version of deep-translator via pip, as well as a few other libraries. You can do this with the included environment file. In your terminal, enter:

conda env create --file environment.yml
conda activate jtranslate

You can also reset the environment by running:

conda deactivate
conda remove --name jtranslate --all
conda env create -f environment.yml
conda activate jtranslate

Note: Copy and execute each line one by one—do not run them as a block. Caution: The googletrans API, as used by deep-translator, may face connectivity issues if you're behind a firewall. To improve accessibility in such environments, consider using the --delay option to introduce a pause between retries.
