Linting not showing 'undefined-variable' error with 'generated-members' pylint args

Environment data

• VS Code version: 1.45.0, official version (from AUR package visual-studio-code-bin)
• Extension version (available under the Extensions sidebar): 2020.5.78807
• OS and version: Arch Linux
• Python version (& distribution if applicable, e.g. Anaconda): miniconda, both python 3.8 and python 3.7
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): conda
• Relevant/affected Python packages and their versions: XXX
• Relevant/affected Python-related VS Code extensions and their versions: python extension
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info #3977): Jedi
• Value of the python.languageServer setting: Jedi

Additional Settings:

• I am programming on a remote server using SSH extension (Remote - SSH 0.51.0 from Microsoft)
• I have added the following pylint arguments:

    "python.linting.pylintArgs": [
        "--generated-members=numpy.*,torch.*"
    ],

Expected behaviour

I have a file in which there is an error, by mistake I used a wrong name for the variable. Therefore, in the editor, it should be marked in red in the editor.

Actual behaviour

The error is not reported on the editor, I don’t get any indication that there is one, as you can see in this image However if I run pylint with the same arguments I get:

src/nn_utils.py:464:50: E0602: Undefined variable 'model' (undefined-variable)

amongst the rest of the warnings.

Steps to reproduce:

I can’t put the whole file of code, but I can give this small snippet which exemplifies the problem:

    torch.save(net, name_file+".net")
    sources_ = sources(NUM_SOURCES, net, model_, max_batch=num_samples, T_obs = T_obs)
    if T_obs > 0:
        probs = calc_average_conf(NUM_SOURCES,net,model,T_obs=T_obs,max_batch=num_samples)
        name_csv = name_file + "_obs_T_{}.csv.gz".format(T_obs)
        probs.to_csv(name_csv,index=False)

1. Save the file
2. Observe the line decoration

Logs

Output of the Python extension:

Your code has been rated at 4.86/10 (previous run: 4.86/10, +0.00)

Personal considerations

So the error is caught by the extension, but it is not displayed in the editor in any way (see the link above). If I remove the pylint args in the settings, the error is displayed again, but so are all the - incorrect - errors of "numpy has no member… ".

As in the first post about the issue, the Python log shows the error when linting, it’s simply not displayed in the editor.
