jupyter 笔记本中的 ModuleNotFoundError

Question

The questions was already asked, but I have problems applying the answers.

I want to use scipy in the jupyter notebook and when I run

!pip3 install scipy

it says that scipy is already installed. When I try importing it now I get the ModuleNotFoundError message. One solution to this question was that the path in the notebook is different and one should change it with

import sys
sys.path.append('your-path')

The problem is I don't understand what is happening here and I actually can't find the path of my python packages. I am using a Macbook with macOS 10.15.5 and python 3.8.3.

Answer 1

You have two different pythons, point to the correct one, and run.

Mac since built on top of linux comes with default python 2.7.

So, find which python you have installed python package scipy.

Then, Point your IDE to it and run it, by changing settings.

You can find python by using where python in terminal.

Then run

/Your/python/here/python* -c "help('modules')"

This will display if the python you're running has the package installed or not.

Finding where it is, is upto you. But pretty sure, that's the issue here.
