Installation problem: No module named 'retro._retro' about retro HOT 6 CLOSED

Question, what happens if you are not in the project directory?

from retro.

From other directories, I get the same error as the second attempt above, after the cd .. - the ImportError: dlopen(... one.

from retro.

Sorry, didn't see that. My bad!

The issue for the first error is caused by python looking at the source directory to resolve the retro import (which will not contain _retro, as it's a shared object that gets built and placed elsewhere). As you have seen, moving directories resolves that issue.

Once past the first issue, you're hitting this one:

cython/cython#1880

To confirm, you ran pip install -e . inside the directory. What happens in that directory if you run python3.5 setup.py install?

EDIT:
Which versions of python do you have installed on your machine?

from retro.

What did you use to install Python 3.5? The builders use miniconda.

from retro.

That was a great idea. I deleted my existing Python installs (not the native 2.7 version on the Mac, though) and installed a fresh Anaconda with Python 3.6. Then I downloaded the binary for that version from the document page, and I can import retro and run the list of games. So this may have been down to a confused Python installation, solved by just trashing everything and starting over. Thanks for the help! I think this particular issue can be considered closed.

i have the same problem gym retori is not found when running the randome agent python.
i ran the python3.5 setup.py install command but that did not work but python3.6 setup.py install did do something.
