Install problem with anaconda

[jjlk]

Dear all,

I'm trying to install the pyhessio module to start working with ctapipe. I'm following these instructions (https://cta-observatory.github.io/ctapipe/getting_started/index.html):
git clone https://github.com/cta-observatory/pyhessio
conda build pyhessio
conda install --use-local pyhessio
The last command returns an error linked to conflict packages:

(cta)[julien@touques] ctasoft $ conda install --use-local pyhessio
Using Anaconda Cloud api site https://api.anaconda.org
Fetching package metadata: ......
Solving package specifications: .......
Error: Unsatisfiable package specifications.
Generating hint:

Hint: the following packages conflict with each other:

• pyhessio
• python 3.5*

Use 'conda info pyhessio' etc. to see the dependencies for each package.

Do you have any idea how to fix this ? For informations, I'm using Mac OS X 10.11.3 and the latest version of anaconda (for python2.7 but I created a virtual environment as suggested in the previous link). You can find the log of the build command in the attached file log_build.txt.

Best regards,

Julien

I can reproduce this issue.
As a workaround you can do:
source activate cta
cd pyhessio
python setup.py install

Thanks, the solution works fine.

When you install anaconda, you get it for a specific version of python.
Today (March 10 2016) is python 3.5

But few weeks ago it was for python 3.4
If you have installed anaconda for python 3.4 you can not build conda package for python version upper to 3.4.

So you have the choice:

Either you create a conda env for python 3.4, and build pyhessio for python 3.4.:
#conda create -n cta python=3.4 astropy matplotlib scipy scikit-learn numba cython

Or you uninstall your current anaconda and install anaconda for python 3.5
