ImportError: cannot import name 'MyClass' from "myFile.py", without restarting the notebook

Using VSCode, I have a file myFile.py with a class myClass

# myFile.py
class myClass(nn.Module):
    def __init__(self):
         super(myClass, self).__init__())
         self.a = 1

No in a JupyterNotebook someNb.ipynb inside the same folder as myFile.py I just want to import myClass in a python cell:

from myFile import myClass

However, even though I am saving both files (as stated in other questions), I get the following error:

ImportError: cannot import name 'myClass' from 'myFile' (<path-to-myFile.py>) 

I also tried to add

%load_ext autoreload
%autoreload 24

before from myFile import myClass, but also this does not see the changes in myFile.py.

Note: When I reopen the notebook it works. And <path-to-myFile.py> is the correct path.

So the issue is more: Why do I need to reopen the whole notebook everytime I am making changes to myFile.py? I just want to make changes to myFile.py, save both someNb.ipynb and myFile.py, and import the new changes (classes), without reloading the notebook and loosing all variables.
