ModuleNotFoundError: No module named 'Jetson'

Iam on Bookworm and followed the tutorial for linux:

sudo apt-get update
sudo apt-get install python3-pip
sudo apt-get install python3-pil
sudo apt-get install python3-numpy
sudo pip3 install RPi.GPIO
sudo pip3 install spidev

But iam getting ModuleNotFoundError: No module named 'Jetson'.

Can someone help? The C Tutorial and Demo working fine. - i need python...

hey
i'm facing the exact same issue.. I also have that 2in13d product like yours
please let us know if you managed to solve this issue :)
cheers .t.w.

edit: btw fyi i'm working raspberry pi 4

[TWelten]

well, i found a way to avoid having to use Jetson module
DISCLAIMER : the following is not an appropriate solution, it is not fixing fundamentally the issue

Going in the file : ~/e-Paper/RaspberryPi_JetsonNano/python/lib/waveshare_epd/epdconfig.py
you can force the program to use the RaspberryPi() class. At the bottom, in the else condition, instead of having implementation = JetsonNano() change it for implementation = RaspberryPi()
That way I managed to get the demo working fine on my raspberry pi 4 (python3)

Yet i'd like better having a nicer fix to offer..
cheers .t.w.

This is likely the same issue as #306

The underlying issue is how the epdconfig class is trying to detect which hardware you're using, which fails on Raspberry Pi OS 12. There is a fix #307 but it has yet to be merged.

I think this might be the same issue as #313. It looks like several modules are still trying to import RPi.GPIO when it is no longer needed.

Impacted modules:

• epd2in13d
• epd2in9d
• epd4in01f
• epd4in2_V2

I've fixed this in PR #324, but don't have these models to test with; they get flagged by my general-purpose epdlib as being incompatible. I've narrowed down the problem to the import and that appears to fix the problem.
