Import pandas on jupyter ipython notebook not working

Question

I can import the pandas package inside the spyder ide; however, if I try to open a new juypter laptop, import will fail.

I am using Anaconda package distribution on MAC OS X.

That's what I'm doing:

In [1]: import pandas 

and this is the answer I get:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-5-97925edf8fb0> in <module>()
----> 1 import pandas

//anaconda/lib/python2.7/site-packages/pandas/__init__.py in <module>()
     11                       "pandas from the source directory, you may need to run "
     12                       "'python setup.py build_ext --inplace' to build the C "
---> 13                       "extensions first.".format(module))
     14 
     15 from datetime import datetime

ImportError: C extension: hashtable not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext --inplace' to build the C extensions first.

Answer 1

You have several Python 2 engines installed. One on your main OS platform, the other in Anaconda's virtual environment. You need to install Panda on the latter.

Run the Bash command prompt:

which python

Then run the following in Jupyter / IPython and compare the result with the output obtained from the Bash script:

from sys import executable
print(executable)

, (.. ), Bash :

<the 2nd output> -m pip install pandas

:

/usr/bin/anaconda/python2 -m pip install pandas

Pandas Anaconda Python.

, sys.path.append('path to alternative locations'), , , .

:

python -m pip install cython scipy panda matplotlib jupyter notebook ipython

Update:

homebrew :

xcode-select --install

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Answer 2

Mac OS X Anaconda (Python 2). pandas python repl :

ValueError: unknown locale: UTF-8

~/.bash_profile:
