PySmile: Compatibiltiy with Pylint?

[maghnie]

As part of my framework's Git CI pipeline, there's a code quality stage that uses Pylint.
However, the CI fails with these warnings and error:

Is there a specific flag or parameter that can be passed on to Pylint, to let it handle PySmile properly?

I've tried ignoring import warnings but that didn't work. Currently, we just set up a different virtual environment that doesn't include PySmile to make the code linter work.

This workaround is acceptable. So it would just be a bonus if PySmile would work with Pylint too.

[piotr [BayesFusion]]

The problem found is not caused directly by Pylint - this one is compatible with the code in which there are PySMILE objects.
A series of errors - No module named '_pysmile' suggests that our library is imported as an alias - can you share the code and write more about the CI tools you use to deploy the project?

[maghnie]

Thanks for the prognosis!

Since I may not share the actual code, I've tried to recreate the error locally with just 2 files: tutorial1.py and an __init__.py
(

).

To recreate the error:

1. Create and activate a conda virtual environment with Python 3.12.4
2. Run:

   Code: Select all

   pip install pylint && pylint .

3. Commands runs successfully with this output:

   Code: Select all

   Your code has been rated at 3.23/10

4. In the same terminal, install pysmile and rerun pylint

   Code: Select all

   pip install --index-url https://support.bayesfusion.com/pysmile-A/ pysmile && pylint .
   

5. Now the pylint command results in an error:

My local environment, as you can tell, is Windows. But the CI is running on Linux. So the issue is probably OS-independent.
Also, including or excluding the pysmile license file doesn't change the outcomes.

Any hints are appreciated!

[piotr [BayesFusion]]

It turned out that the fault lies with PySMILE installed by pip. When installing wheel in the modules directory (site-packages), PySMILE leaves an unnecessary __init__.py file. It has the same modification date as pysmile.pyd on Windows and pysmile.so on Linux.

It is safe to remove it manually, however, we will soon update our repository so that the unnecessary would not be part of wheel anymore.

After removing this file, any messages about an unknown module disappear and pylint works properly. Interestingly, outside the conda environment, everything works properly and the redundant __init__.py file does not affect anything.

Will keep an eye out for the package update! Thank you for the explanation :)
