在命令行上运行python脚本失败

Question

I'm trying to run a python script on my Windows 10 Computer. The structure of the directory looks as follows

MyProject
   - src
      - main.py
      __init__.py

      - features
          - featureExtraction.py
          - __init__.py

The main folder is "MyProject". In "MyProject" is a subfolder called "src". In "src" the files "main.py" and " init .py" as well as the folder "features" exists. In the folder "features" there are the files "featureExtraction.py" and " init .py".

In "main.py" I have the following import:

import src.features.featureExtraction

When I run main.py within pycharm everything works, but when I start the script on the command line using "python main.py" (beeing in the src folder), then I'm getting an error:

ModuleNotFoundError: No module named 'src'".

Why does this happen?

Answer 1

You said you executed import src.features.featureExtraction while in the src folder. That import makes sense only while you are in the parent MyProject folder.

In pycharm prefs, search for Project Structure and notice the content root (MyProject) that it is using. That explains the different behavior you saw from IDE and from command line.
