lazy loading modules causes sphinx documentation to break #37

Open rsokolewicz opened 1 year ago

rsokolewicz commented 1 year ago

Hi,

I found an issue where building a sphinx documentation breaks when one of our package's dependencies lazy loads a package.

In our particular case we depend on qcodes that lazy loads the h5py package.

When building the documentation, it fails with the following trace stack 

[AutoAPI] Reading files... [  1%] /home/docs/checkouts/readthedocs.org/user_builds/quantify-quantify-scheduler/checkouts/545/quantify_scheduler/gettables_profiled.py

    for key, value in values.items():
RuntimeError: dictionary changed size during iteration

which is not very clear to me. I can make the build succeed by adding the line import h5py to docs/conf.py, so the root cause is very likely due to the lazy loading of h5py.

I don't have a nice minimal working example, other than cloning our repo and building the documentation yourselves:

mkdir tmp
cd tmp
git clone --no-single-branch --depth 50 git@gitlab.com:quantify-os/quantify-scheduler.git .
git fetch origin --force --tags --prune --prune-tags --depth 50 merge-requests/545/head:external-545
git checkout --force a7cc1ff360a2da8bb64f44f405a5b7bc5f3389fc
git clean -d -f -f
conda create --name tmp python=3.8
conda activate tmp
pip install quantify-scheduler
pip install -r requirements_dev.txt
pip install qcodes==0.36.0
cd docs
python -m sphinx -T -E -b html -d _build/doctrees -D language=en . _build/html

which fails, but after a echo "import h5py" >> conf.py and running the sphinx build again it succeeds.

Before I investigate further, can you confirm that this is still an issue @rsokolewicz?

rsokolewicz commented 1 year ago

Hi Stefan, it's still an issue yes, but it doesn't block any of our development. As I mentioned, we can add an import h5py line to conf.py that is used by sphinx when building the documentation and resolves the issue.

I was playing around just now and can tell you that the error is caused by the autoapi extension of sphinx. This generates an API page with documentation and cross references to all modules/classes/methods. My guess is that something goes wrong in creating a cross reference to a member of a lazy loaded package. It could very well be that the issue should be solved by autoapi and not you guys.

Is this the same traceback you see?
