7.6.5: pytest shows some DeprecationWarning

[kloczek]

Description

I'm trying to package your module as an rpm package. So I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I'm calling build with --no-isolation I'm using during all processes oly locally installed modules
• install .whl file in </install/prefix>
• run pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Here is pytest output with deprecation warnings:

+ PYTHONPATH=/home/tkloczko/rpmbuild/BUILDROOT/python-ipywidgets-7.6.5-2.fc35.x86_64/usr/lib64/python3.8/site-packages:/home/tkloczko/rpmbuild/BUILDROOT/python-ipywidgets-7.6.5-2.fc35.x86_64/usr/lib/python3.8/site-packages
+ /usr/bin/pytest -ra
