I'm having trouble installing the environment.

$ conda env create -f environment.yml
Warning: you have pip-installed dependencies in your environment file, but you do not list pip itself as one of your conda dependencies. Conda may not use the correct pip to install your packages, and they may end up in the wrong place. Please add an explicit pip dependency. I'm adding one for you, but still nagging you.

There were some more pip errors, and then when I tried to activate the environment, I got:

Could not find conda environment: stat-rethink-pymc3
You can list all discoverable environments with conda info --envs.

Should I try to install PyMC3 in my deafult environment instead?
