为什么python 3.6.1在成功安装后无法识别numpy或pil或skimage

Question

I am getting these errors trying to run a python3 program in itelliJ IDEA on a mac.

import numpy as np
ModuleNotFoundError: No module named 'numpy'

from PIL import Image, ImageChops
ModuleNotFoundError: No module named 'PIL'

from skimage.feature import match_template # requires numpy, scipy, and six
ModuleNotFoundError: No module named 'skimage'

All of these modules have been successfully installed using pip3. I have confirmed the installs using IDLE. Clearly, it seems, there is more to it than simply installing, but I don't know what it is.

I cannot find anything that addresses concerns on python.org. They, in fact, refer me to Stackoverflow. The closest I found here dealt with numpy and python2.7 on mac. There are no responses to that one.

Answer 1

Look in the Preferences for the Project Interpreter setting, and make sure it's pointing to the right python version.

Secondly, since you're already using and IDE use PyCharm. It's IntelliJ's python specific IDE, and it'll have better documentation on python specific technical problems.
