Autocomplete not working in Pycharm

While using plotly 4.0 combined with Pycharm the autocompletion for plotly.graph_objects is not working. Also the references to the objects are not found either, but the script does work. I see some people on the community site with the same issue.

Works fine for e.g. pandas:

No completion is found when I type go. either.

However when I use import plotly.graph_objs as go, the references are found. But the autocompletion still doesn’t work. I have tried File > Invalidate Cache/Restart, to no avail.

There has been an issue like this before but it seems it had been solved: https://github.com/plotly/plotly.py/issues/389

When I open the same virtualenv within VScode the autocompletion works fine. (The extension uses jedi for autocompletion I think).

I am not sure if this is an issue with plotly or pycharm.

It looks like it has something to do with the graphs_object file being to big:

This can be solved (on mac) by going to:

Help > Edit Custom Properties

Then add:

idea.max.intellisense.filesize=500000

Then restart Pycharm (Stackoverflow link)

After this intellisense worked as expected:

How about changing if guard here https://github.com/plotly/plotly.py/blob/master/packages/python/plotly/plotly/graph_objs/__init__.py to

if sys.version_info < (3, 7) or TYPE_CHECKING:

this solves an issue with vscode+pylance for me, and in runtime the import is still lazy. Shall I make a PR?
