autosignature warnings + complicated setup

[myselfhimself]

trafficstars

Hello,

I would like to remove warnings mostly. I describe my setup below:

I am trying this in a .rst file for the gmic-py purely compiled C/C++ Python binding which has C docstrings:

.. autosignature:: gmic.GmicImage.from_PIL :nosummary: :debug:

For it to work I had to do three things:

• add pyquickhelper and sphinxcontrib.imagesvg to my docs/'s requirements.txt
• add import gmic and add pyquickhelper.sphinxext.sphinx_autosignature to the extensions array variable, within my docs/conf.py

after this, when building HTML with sphinx, I get the following log with warnings regarding a package import attempt:

build a réussi, 3 warnings.

Les pages HTML sont dans _build/html .

the result is:

How do I:

• simplify the setup (namely import gmic in conf.py is strange.. but all is OK for me)
• remove the warnings ?

Thanks for your help!

[myselfhimself]

OK sorry the above readthedocs.io error is due to an old sphinx version by default on this platform, I managed to overcome it..

[myselfhimself]

OK autosignature is now used at https://gmic-py.readthedocs.io/en/latest/PIL.html for the first two black links I have decided to ignore the warnings for now..

[sdpython]

To fix it, I would probably add a parameter in conf.py to disable warnings. Would that be ok for you?

[myselfhimself]

yes

[myselfhimself]

Thank you

[sdpython]

I looked into the code and the logging [import_object] ... should not appear unless :debug: is added as on option to the directive. The warning WARNING: [autosignature] should not appear unless the directive does not work. I looked at https://gmic-py.readthedocs.io/en/latest/PIL.html and it looks ok. I guess I'll have to build and run the documentation to fully understand what's happening.

[myselfhimself]

ok thank you for kindness Xavier I have accepted to build with warnings
