Importing CPM

[FloorJBurghoorn]

I installed CPM on my pc (running Windows 11) using pip install git+https://github.com/DevComPsy/cpm.git. I did this using Anaconda Prompt, and made sure to install it in the same environment as my Python interpreter in Spyder (i.e., my-env). If I say pip show cpm-toolbox, it gives me the correct information (e.g., I installed version 0.23.18, etc.). FYI, pip show cpm does not work (it says there is no such package), but perhaps that's fine.

In the past, I used to be able to use the CPM toolbox without issues after installing it in this way. Now, however, if I open Spyder (with the correct interpreter) and say import cpm, it gives me a ModuleNotFoundError: No module named 'cpm', also after restarting the kernel. I am not sure this is an issue with CPM or something else, but importing other modules (like numpy or scipy) works fine.

I should perhaps mention that Anaconda Prompt does keep giving me the following warning with practically every command I run, but I doubt that it is the cause of the problem: WARNING: Ignoring invalid distribution ~cipy (C:\Users\XXXXX\AppData\Roaming\Python\Python313\site-packages). I already uninstalled and reinstalled scipy but the warning remains. Just mentioning it in case it turns out to be relevant after all.

Does anyone have suggestions on how to fix this?

Thanks for reporting this. I will go one by one.

The first point is about pip show cpm returning an error like this (I assume): WARNING: Package(s) not found: cpm. This is fine, because the pip-indexed package name is cpm-toolbox and not cpm. The reason for this is to avoid name-clashes with some other older packages. You still use it as before, by import cpm.

In terms of the Spyder issue, I need more information. Can you please first of all share the output of pip show cpm-toolbox?

Furthermore, can you please also share the output of the following commands?

# In Spyder
import sys
print(sys.executable)

In the command line:

## In the command line
conda activate my-env
where python  # (or 'which python' on Mac/Linux)

Thanks for your fast reply! I think you are on to something here, because while the Spyder command gives me C:\ProgramData\spyder-6\envs\spyder-runtime\python.exe (which I am surprised about given that the interpreter has been set to my-env), the command line gives:

C:\Users\XXXXX\miniconda3\envs\my-env\python.exe
C:\Program Files\python.exe
C:\Users\XXXXX\AppData\Local\Microsoft\WindowsApps\python.exe

However, I never changed anything about Spyder, so I am surprised that suddenly this would cause problems.

Yeah, seems about right. I think Spyder can be a bit random in what python environment it points to... I mark the discussion as outside of the software, but feel free to post the solution once you find it. I am sure it will be helpful for others.

Alright, after messing around with this for a while it turned out that although Spyder seemed to use the right interpreter, it did not really. Making sure that it used the right interpreter (through tools > preferences > python interpreter and then select the environment in which I installed cpm) fixed the issue, and allowed me to import cpm without issues. Sorry for polluting the CPM forum with this but thanks a lot for your help!!

It seems that it has been resolved via this #63 (reply in thread). So, I will close this issue.
