Module Not Found Error when running app.py on raspberrypi 4b

[jose25h]

Hello,

I recently purchase a WAVE ROVER and I'm been having difficulties getting app.py to run.

After following the installations instructions for raspberry pi 4b, app.py won't work due to “Module Not Found Error” in Python for the following modules:

yaml
flask-socketio
aiortc (requires av 10.0.0-1+b1)
imageio
picamera2
depthai

After manually installing the modules I was able to run the application, however some of the modules I had to use the pip --break-system-packages to force the installation.

I also downloaded and try the provided image for raspberrypi 4b as a test:

And the same issue occurs, app.py won't run without manually installing the missing modules.

Have you have the same issue? Is there an newer version of the app? is there an specific version of the app for the WAVE ROVER robot?

For model selection in the app is " s 10" the correct code for WAVE ROVER?

Thank you ,

i faced the same issue. modules were not installed because requirements.txt contains a dependency on line 5 which can't be installed and interrupts the installation of other modules: https://github.com/waveshareteam/ugv_rpi/blob/main/requirements.txt#L5

after commenting out this one line (changing it to # arandr==0.1.11 i was able install requirements.txt successfully with:

source ~/ugv_rpi/ugv-env/bin/activate
pip install -r requirements.txt

then starting the app with the same command as found in autostart.py:

XDG_RUNTIME_DIR=/run/user/$(id -u) ~/ugv_rpi/ugv-env/bin/python ~/ugv_rpi/app.py
