Hey everyone,
I installed pandas via pip git
pip install git+git://github.com/pydata/pandas.git
and during the installation it says:
Running setup.py install for pandas ... done
Successfully installed pandas-0.18.0+207.gc6110e2
But when I want to import it, it gives an error
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.
I already tried to run this but the response is always:
python: can't open file 'setup.py': [Errno 2] No such file or directory
Maybe I am in the wrong directory. So in which I am suppose to run it? Also I looked in site-packages but can't find pandas or something similar.
I am confused since it said it runs the setup.py during the installation...
Can anyone help? What I am doing wrong?
Thanks in advance
Leni

are you trying to contribute? you need to git clone, see here
otherwise see installation instructions here
generally a pip install pandas (or much better is simply to use conda).
I think that pip doesn't install the deps correctly if you are installing like this (and that its failing because you don't have the build deps installed, e.g. cython/numpy).

Think the error message from pandas could include --force

@MaximilianR that's a good point. do you want to PR for an extended message?

I tried conda before but it is the same problem with importing. So I tried it in an new created environment and without. Installing seems to be always fine. Just importing is the same problem always
adding -force doesn't help since it can't find setup.py at all such that it still gives the error
Comment From: lherstix
so I found now the pandas in
/anaconda/lib/python2.7/site-packages
but still can't find any setup.py
Comment From: jreback
once you install via anaconda you don't need to do anything else.
conda create -n test pandas
source activate test
python -c 'import pandas; print(pandas.__version__)'

Great it worked, except form another name of the environment I don't what I did different last time. However, it worked! So thanks a lot!!! :) Could just explain me why do I need this environment?
Comment From: jreback
@lherstix you don't :> that was just a test the -n <name_of_environment> can be anything. its up to you (and you can have multiple ones). http://conda.pydata.org/docs/

Thanks a lot, that helped :)

Me again...
So after pandas worked fine, I installed seaborn the same way and in the same environment. Now I get an error for pandas and for seaborn when I import them:
import pandas as pd
import seaborn as sns
I get the following error:

I hope it is understandable and you can help me! Greatz!

@lherstix I suppose you are running a Mac? See http://conda.pydata.org/docs/troubleshooting.html#issue-valueerror-unknown-locale-utf-8-on-os-x
