Can't show *.ipynb files rightly

[BAOOOOOM]

*.ipynb files can not be shown by nbsphinx. And show as this:

Actually, if I use sphinx to build it locally, it can show in right format, just like this:

Thank you!

I have used the method of #310, but the bug stills existence.

I had the same problem. Seems to have appeared with nbsphinx 0.8.7. I was able to build my docs correctly with sphinx 4.1.2 and nbsphinx 0.8.6.

The main change from 0.8.6 to 0.8.7, concerning this problem, is that the .ipynb extension is now added to sphinx's source suffixes ONLY if it is absent from the base config (the config as it is after executing conf.py).
And it turns out I had this line in my conf.py:

source_suffix = [".rst", ".ipynb"]

Thus, nbsphinx was never registering notebooks to be parsed by the correct parser. Sphinx was reading them as if they were rst files. I am not sure why I add that line before, but removing the ipynb part solved my problem. @BAOOOOOM maybe you have something similar in your code?

[BAOOOOOM]

Yes, I have something similar in your code. Now the problem is sovled. Thank you very much.

source_suffix = [".rst", ".ipynb"]

Using a list as source_suffix does not do what you expect, see https://www.sphinx-doc.org/en/master/usage/configuration.html#confval-source_suffix

Since .rst is Sphinx's default and .ipynb is automatically added by nbsphinx, setting source_suffix is not necessary at all.
