Problem Description

I am experiencing that Spyder UMR does not reload modules, when import these modules as an entire .py file.

So, for instance, in my project, I have a folder called "Modules".
In this folder I have several .py files, which I use as different modules in my project.

If I import a specific function (my_func) within a module (my_module.py file located in the Modules folder), using:

from Modules.my_module import my_func
The UMR manages to reload the my_module every time.

If I just import the module directly using:

from Modules import my_module
The UMR does not reload the my_module module

These modules typically contain more than one function, so it convenient for me to import an entire module instead of importing the specific functions within the module.

Is there a way to fix this, or do I have to import the functions individually, to get the UMR function to work as intended?

What steps reproduce the problem?

1. from Modules import my_module
2. run whatever script that is using my_module

What is the expected output? What do you see instead?

I expected that my_module is being reloaded every time I run the script, which then uses my_module.my_func() at some point.
But this is only the case, when I import the function specifically as
from Modules.my_module import my_func

Hi,

I have this exact same problem using the new Spyder version:

• Spyder version: 6.0.2 (standalone)
• Python version: 3.11.10 64-bit
• Qt version: 5.15.8
• PyQt5 version: 5.15.9
• Operating System: Windows-10-10.0.22631-SP0

Any fixes or updates on the matter?

Kind regards,
Hjalte

Hi @Jesperten and @hbengtsson sorry for such a late response! Checked this with the latest Spyder version (6.0.4 as I write this) and I was able to reproduce this using the UMR feature.

Further checking, seems like disabling UMR (Preferences > Python interpreter > User Module Reloader (UMR)) and instead using the IPython console Autoreload option (Preferences > IPython console > Advanced settings > Autoreload) should be enough to be able to reload modules used in the from Modules import my_module to use functions using my_module.my_func():

Let us know if the info above helps!

Hi @dalthviz,

This seems to resolve the issue. Thank you for following up!
