@dsaxton Can I ask why this test is failing?
Is this Issue solved?

[Shubhamsm]

Hi @dsaxton , I've removed many unnecessary backticks
now I cann't find problems that are failing the test.
can you tell me what other problems I'd made in the commits

[dsaxton]

Hard to say with so many changes what would make the doc build pass. Part (but perhaps not all) of the reason is these warnings (CI fails if warnings are raised during the doc build), so you could start by fixing those:

2020-09-25T18:31:10.2551420Z Differences to R's ``factor``
2020-09-25T18:31:10.2552161Z ---------------------------
2020-09-25T18:31:10.2553014Z /home/runner/work/pandas/pandas/doc/source/user_guide/categorical.rst:1016: WARNING: Title underline too short.

Can you also merge master? Several files were just fixed.
