Configurations in `pyproject.toml` seem to be ignored

Jupytext version: 1.13.1 Python version: 3.7.5

I have a project structure similar to the following:

project/
   |-pyproject.toml
   |-module/
      |-submodule_1/
      |-submodule_2/
         |-tests/
            |-test_notebook.ipynb

I added the following to my pyproject.toml file:

[tool.jupytext]
formats = "ipynb,py:light"

I am running jupyter from the project directory where the pyproject.toml file is also located. However, it seems that the configurations are ignored. When I save test_notebook.ipynb no .py file is generated or if there already is one, it doesn’t get updated.

If instead of modifying the pyproject.toml file, I create a jupytext.toml file at the same location and with the content

formats = "ipynb,py:light"

everything works as expected, test_notebook.ipynb is paired properly.

Am I doing something wrong when trying to configure jupytext through the pyproject.toml file? Or have I perhaps stumbled on a bug here?

And last but not least, thank you for the fantastic library.

Sorry for letting this issue sit stale for such a long time. I will try to get back to it in the coming days and give your latest suggestions a go.

OK, I think I have a similar issue which is that the pyproject.toml is actually picked up in the --notebook-dir that is set for jupyter when you start it. So for instance for instance, my data is in ./data and the pyproject.toml needs to be there as well otherwise it doesn’t know how to sync (in my case) md and ipynb files.

This was puzzling to me for a long because sometimes I start jupyter lab at the home directory . and sometimes I set the --notebook-dir to ./data and the sync and reading of pyproject.toml happens in the former but not the later case.
