Package installed by Conda, Python cannot find it

Question

I am trying to install Theano Anaconda. It works, but when I enter python -i, it import theanoshows No module named 'theano'. Do I need to switch another Python interpreter like? Also, for packages installed by conda, if I do not install them twice, can I find in Python? How is Python related to Anaconda Python? Thank!!!

Answer 1

You can access a specific version of python using the following line in the first line of your .py file. This is for python 2.7

#!/usr/bin/env python2.7

This is for python 3

#!/usr/bin/env python3

, , sys. :

import sys
print(sys.path)

sys.path :

sys.path.append('/path/to/the/folder/of/your/module/file')

PYTHONPATH.
