Custom package isn't installed #4

Closed moorepants closed 7 years ago

moorepants commented 7 years ago

The enviroment.yml file is very nice way to get everyone setup but it doesn't install the custom package in the repo. Apparently you can add something like pip install -e . to the environment.yml as a fix. Other options are to make it a real conda package or just put some kind of sys.path.append(...) calls before imports in the notebooks.

It is already a real conda package: https://anaconda.org/SymPy/scipy2017codegen

But if you are making changes to it locally you should remove the last line of environment.yml and run e.g. python setup.py develop (for some reason pip install -e . failed on one of the CI servers, can't remember which). Or do export PYTHONPATH=$(pwd):$PYTHONPATH, or as you said: sys.path.append(...)

Oh good. So I'm not sure why it didin't get installed when I ran the environment.yml command. I'll dig around.

I just updated the README to hopefully clarify this.
