DOC: Fixed warning about convert_objects in doc build

[nadebu]

convert_objects doesn't exist anymore, and the example in the release notes when it was added is failing and generating a warning in the doc build:

Exception in /home/travis/build/pandas-dev/pandas/doc/source/whatsnew/v0.11.0.rst at block ending on line None
Specify :okexcept: as an option in the ipython:: block to suppress this message
---------------------------------------------------------------------------

Thanks for the PR! What warning were you getting? Any easy way to detect others?

I think all the CI failures are unrelated, not sure what's broken there.

But looks like the warning is still in the docs. @nadebu can you see if you find what's wrong?

@WillAyd added more info to the description.

[datapythonista]

@nadebu I see that one file (doc/esample.feather was added by mistake). Can you please remove it?

Also, I think your change is probably fixing one of the errors, but a similar error is happening in the example immediately after in the PR. Can you apply the same change there please?

Thanks!

[jreback]

can you remove the added doc/example.feather file?

[jreback]

rather than this can you change to a code-block (and just show what it was)

[jorisvandenbossche]

@nadebu sorry, it have been working the last days on the documentation, and this has already been fixed in the meantime.

[jorisvandenbossche]

Hopefully you can find another issue to work on! (there are some labeled with good-first-issue)

[jorisvandenbossche]

Also, specifically for #24173 (flake8 in the docs), there are still files left to do, so very welcome to open PRs for those.

[nadebu]

Sorry I missed all this conversation. My mail was being diverted and still familiarising myself with github's messaging.
