No USB cameras found in python process (Pylon viewer works)

[Bonitodelcapo]

Describe what you want to implement and what the issue & the steps to reproduce it are:

I would just like to be able to connect to the camera.

This is the python file

from pypylon import pylon

# List all connected devices
available_cameras = pylon.TlFactory.GetInstance().EnumerateDevices()

if not available_cameras:
    raise RuntimeError("No cameras found.")

print("Available cameras:")
for i, camera_info in enumerate(available_cameras):
    print(f"[{i}] - {camera_info.GetFriendlyName()}")

# Select the first available camera (you can modify this if you have multiple cameras)
camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateDevice(available_cameras[0]))

# Open the camera
camera.Open()

# Display camera model name
print("Camera opened:", camera.GetDeviceInfo().GetModelName())

i checked that udev rules are modified for usb cameras as described in the installation process.

would you test your script with sudo?

why do you use pypylon 2.3.0? you may update to latest version that matches python 3.8
