nbdev_prepare TypeError exception when parsing pycaret import

[castorfou]

not 100% sure this is due to nbdev.

With this simple cell:

#| export
from pycaret.regression import RegressionExperiment

nbdev_prepare or nbdev_docs fails with the folowwing stacktrace:

(pycaret_nbdev) explore@explore-ThinkPad-P53:~/git/guillaume/pycaret_nbdev$ nbdev_prepare

TypeError: enable_matplotlib() takes 1 positional argument but 2 were given

nbdev Tests Failed On The Following Notebooks:
==================================================
        00_core.ipynb
        index.ipynb

it looks like this call gui, backend = self.shell.enable_matplotlib(args.gui.lower() if isinstance(args.gui, str) else args.gui) is analysed as providing 2 arguments (due to ','?)

I have setup a minimalist repo to illustrate: https://github.com/castorfou/pycaret_nbdev

Just a plain new repo with nbdev_new and just added this pycaret import into 00_core.ipynb

As a workaround, I have tried with skip_exec: true in frontmatter. It works locally but not in CI/D (using gitlab not gh)

I think this is caused by an upstream issue tracked in https://github.com/fastai/execnb/issues/42. That should be fixed by https://github.com/fastai/execnb/pull/43.

I'll close this in the meantime and reopen if needed.

[castorfou]

do you know when release 0.1.5 will be created?

[seeM]

@jph00 could we please get an execnb release for https://github.com/fastai/execnb/pull/43?

Absolutely! :)
