Anaconda3 Jupyter Notebook raises AttributeError

[JasonSanchez]

What I am using:
Jupyter Notebook (most recent Anaconda3 release).
Python 3.5.2 |Anaconda custom (x86_64)| (default, Jul 2 2016, 17:52:12)
[GCC 4.2.1 Compatible Apple LLVM 4.2 (clang-425.0.28)] on darwin

Code:
from mr_word_count import MRWordFrequencyCount
mr_job = MRWordFrequencyCount(args=['my_file.txt'])

Issue:
Works in command line/.py script. Does not work in notebook.

Error in notebook:
`---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)

2 from mr_word_count import MRWordFrequencyCount

----> 4 mr_job = MRWordFrequencyCount(args=['my_file.txt'])

129 self.stderr = sys.stderr.buffer

AttributeError: 'OutStream' object has no attribute 'buffer'`

[coyotemarin]

Huh, looks like stdout and stderr are ipykernel.iostream.OutStream objects, which don't have a buffer attribute, but which seem perfectly happy to accept bytes as well as unicode.

I think I'll rewrite this code to look for the buffer attribute explicitly, rather than keying off Python version.

This should be fixed in master. Please try it out and let me know if it works for you.
