Cannot import some packages in PyCharm

Question

I installed NLTK package, and i can import NLTK in Jupyter Notebook, but cannot import it in PyCharm.

>>> import nltk
>>> import sys
>>> print('\n'.join(sys.path))

In jupyter notebook:

/Users/morphy/anaconda3/lib/python36.zip
/Users/morphy/anaconda3/lib/python3.6
/Users/morphy/anaconda3/lib/python3.6/lib-dynload
/Users/morphy/anaconda3/lib/python3.6/site-packages
/Users/morphy/anaconda3/lib/python3.6/site-packages/aeosa
/Users/morphy/anaconda3/lib/python3.6/site-packages/IPython/extensions 
/Users/morphy/.ipython

But in Pycharm:

/Users/morphy/Documents/workplace/practice
/Users/morphy/Documents/workplace/practice
/Users/morphy/anaconda3/lib/python36.zip
/Users/morphy/anaconda3/lib/python3.6

The same error is also occurred when i import other packages like numpy and sklearn.

Please provide the code in your question. An image is not helpful. See here on How to create a Minimal, Complete, and Verifiable examplea https://stackoverflow.com/help/mcve — johnashu, Mar 07 '18 at 03:29
@VivekKumar just the three lines code: import nltk, import sys, print('\n'.join(sys.path)) — Morphy Z, Mar 07 '18 at 06:56
Ok. Then do you have a file called `difflib.py` in your current working directory aside `text_classifier_test.py`. The stack trace says so. See last line of stack trace. And I think thats conflicting with a library level file with same name. — Vivek Kumar, Mar 07 '18 at 07:29
@VivekKumar Thanks for your reminder. I noticed that i had create a file difflib.py. When numpy is imported, it was calling this file instead of it's own library file hence resulting in the error. — Morphy Z, Mar 07 '18 at 22:51

Update: Resolved.

I created a file named difflib.py in my current working directory, hence when numpy is imported, it will call this file instead of it's own library file.

This question is similar to Numpy import throws AttributeError: 'module' object has no attribute 'core'
