I can run the python file in pycharm, but not by using the cmd in Windows (message : no module named xxx)

Question

I have this folder structure:

project:
|-the_package:
|  |-simulator.py
|  |-__init__.py
|-folder:
|  |-file1.py (contains: from the_package.simulator import xxx)

In cmd I type "python file1.py" and i get the following error : ModuleNotFoundError: No module named 'the_package'. Thanks for your help

You might have installed the package in the virtual environment set up by PyCharm. Just install the packages using CMD instead. — samkart, Nov 22 '19 at 09:24

Based on the command you are using, I assume you are running the command inside the folder directory. From there, there is indeed no module or package called the_package.

Instead try moving up a directory, so that you are calling from inside project, and run it as python folder/file1.py.

Sorry I am new in python, I would like to correct my question.

I have this structure:

python_package
module1
file1.py:
init.py
module2
file2.py
init.py
My file1.py contains some parameters which I want to import in file2.py.
In file2 I wrote : from module1.file1 import some_parameters
It is working with Pycharm but not in command line (ModuleNotFoundError: No module named 'module1'), why is that ?

Thanks Again

add a blank file `__init__.py` file inside every folder starting from python package – samkart Nov 22 '19 at 10:52
within the python_package folder as well, since you're calling `from module1.file1 import param1` – samkart Nov 22 '19 at 12:42

I recommend running python -m folder.file1.py inside project folder. Sometimes, import in python is confusing. As far as I know, there is no simple way to solve your case of running inside folder (sibling import). Here is another similar SO question about this issue. Relative imports for the billionth time
PyCharm did some works behind the scene and that is why sometimes there is different behavior. In your case, try unticking "Add content roots to PYTHONPATH" of configuration and then you will get the same error.
