Modulenotfounderror Only Occurred In Conda Environment

I usually use conda environments for my developing, but I faced strange problems in conda env. I cloned this python repository. Then, I tried to run a example, but it failed Module

Solution 1:

Your package has not been installed.

Go to the downloaded folder and type:

python setup.py install

This will install parlai into your environment and you can safely delete the folder.

I suppose this is working outside the env because you have something in your path that link to the folder you put parlai in.
