I am unable to run NumPy in PyCharm, BUT it works fine from Terminal (Mac OS). How do I get NumPy to work in PyCharm?

This is the error message that I am getting from PyCharm:

Traceback (most recent call last): 
  File "/Users/giridhar/PycharmProjects/numpy/testfile", line 12, 
    in a = np.array([1, 2, 3]) # Create a rank 1 array 
AttributeError: module 'numpy' has no attribute 'array'

    Have a look at this: https://stackoverflow.com/questions/36530726/using-numpy-module-object-has-no-attribute-array. Perhaps rename the directory to something else. – cadebe May 23 '20 at 09:04
  • Does this answer your question?

It looks like the Python that is visible to Pycharm and the system python are different. You will have to specify which python interpreter Pycharm should use.

You can do this the following way:

  1. Press Ctrl+Alt+S to open the project Settings/Preferences.

  2. In the Settings/Preferences dialog Ctrl+Alt+S, select Project {project name} | Project Interpreter. Click the The Configure project interpreter icon and select Add.

You can also try adding this to the top of your Python files:

#!/opt/python3.7/bin/python

This will allow you to specify which python interpreter should be used from the terminal. Just make sure that you are using a Python interepreter that already has numpy installed.

  • I run Mac OS. I see Control and S BUT do not see Alt. I see Project Preferences in Edit Configuration . – Giridhar Tirumalai May 24 '20 at 09:40
  • BtB, I did take a clue from what you had mentioned, and changed the Python path. numpy now works in Pycharm. However, when I run my pure Python code ( in a path different to that of numpy) I get stuck. So, it appears I have to change Python Interpreter path when I run numpy and when I run pure Python code. But then, how can I run a Python code that has numpy code? How do I alter interpreter path? to run python + numpy combined code? Should I just have 1 directory for Python ? – Giridhar Tirumalai May 24 '20 at 10:28
