fail to install requirements

[OmriTreidel]

I created a new virtual environment and tried to install the requirement via pip install -r requirements.txt On ububtu 16.04 and python 2.7.12.

the error:

For me, same command worked in Ubuntu 14.04 and python 3.6. Although it said: Ignoring wsgiref: markers 'python_version < "3.0"' don't match your environment I'm not sure if I am going to run into some problems later.

UPDATE: did ran into problems. The jupyter notebooks are written in python 2.7. (Should have been mentioned clearly in the README). I have now made a conda environment file to install whatever is required for the book. Here's a link. The environment file (yml) can be installed by this command: conda env create -f baye.yml

I see the same problem. It seems that pymc expects numpy to be completely installed before its setup.py is run.

See a related issue and background at statsmodels: 0.8.0rc1 implicitly requires numpy to be pre-installed · Issue #3207 · statsmodels/statsmodels

Thankfully, pymc3 installs with requirements.txt seem to work, as seen in #441
