Hmm @gueletk also has the "See Also" changes in https://github.com/pandas-dev/pandas/pull/23653

@syutbai would it be hard for you to revert those changes, so that there isn't a merge conflict?
Looks like git manages the merge ok.

@syutbai can you fix the linting errors on travis, so we can merge:
```
./pandas/core/frame.py:354:5: W191 indentation contains tabs
./pandas/core/frame.py:354:5: E101 indentation contains mixed spaces and tabs
./pandas/core/frame.py:1923:80: E501 line too long (80 > 79 characters)
```
@datapythonista Sorry for the tabbing issues.  I pushed the changes to my branch.  Do I need to do another pull request or are we good for merge now?  Thanks!  
Updating the branch is good enough, no need to open a new PR.

I see travis is still red, can you take a look and see what is wrong? I'm in my phone and can't check myself right now.
I see the following error but the script ends with 0:
``` 
3 Errors found:

=============== 75 passed, 4 xfailed, 5 warnings in 3.48 seconds ===============
The command "ci/script_single.sh" exited with 0.
```

The other script ends with exit code 1 but I'm unable to tell where the error is:
```
=================== 5 passed, 12 deselected in 0.04 seconds ====================
Doctests interval classes DONE
Check that requirements-dev.txt has been generated from environment.yml
Check that requirements-dev.txt has been generated from environment.yml DONE
The command "ci/code_checks.sh" exited with 1
```
The line causing the failure is at https://travis-ci.org/pandas-dev/pandas/jobs/454288173#L2823
```
./pandas/core/frame.py:1923:74: W291 trailing whitespace
```

not sure about why the errors you posted aren't failing the build, but @datapythonista will look at that separately I think.
I pushed the change.

How did you identify the file and line number with the issue?
Restarted the failing travis build. Not sure what's up with it.

All green. Thanks @syutbai!
The exact error was in the travis log. But it's difficult to see if you're not used to it. We're workingon making the errors much clearer in the CI, hopefully that will be deployed soon.
