ReadTheDocs is failing to build about pycalphad HOT 10 CLOSED

@mattjj I can reproduce the same error we talked about earlier (#25) on ReadTheDocs, and locally. If I pre-install numpy and scipy into a clean environment (for time's sake) and then run python setup.py install on pycalphad, I get the same error complaining about something in autograd's setup.py.

Just to clarify, the problem is that the name __builtins__ is defined but it's a dict instead of a module, right?

It sounds like __builtins__ is an implementation detail and relying on it is not good form. I tried to remedy this problem in the autograd setup.py file but failed and gave up. I'll let you know if I get it working but I'm not sure when I'll get a chance. Let me know if you make any progress on your end.

Do you know why it's failing in some environments but not on our Travis builds (which check 2.7 and 3.5)?

Oh hey check this out and, even better, the doc page it links to.

I think this could be a good solution! I'm going to try it.

Is it feasible for you to try the builtins-when-setup-is-not-main branch of autograd? I applied the fix linked above and I think it might solve your build problems.

I'll give it a shot.

I just installed that branch into a clean environment with all of pycalphad's other dependencies and python setup.py install worked. If I try to do the same thing against the autograd on PyPI, it fails. However, if I install autograd's master branch, it also works. I'm thinking it's more a function of being preinstalled (and thus hooking into something setuptools is doing). I'm not sure there's a way to figure out if your fix works without involving PyPI somehow.

I'm going to play with the requirements.txt file on RTD and see if I can't bypass this issue by preinstalling autograd.

from pycalphad.

I'm pretty confident that new setup.py will fix the error you were running into, and it didn't break anything in autograd, so I just merged it into the master branch.

from pycalphad.

I updated the docs/requirements.txt file to include autograd in 98d09d7 and (after fixing a bug in 8f535c7) now RTD appears to build correctly. Thanks again for the help @mattjj

Happy to help! Cool project!
