I wanted to run the camera in picrawler, so I ran display.py in the samples.
Initially, it was resolved by typing pip3 install opencv-python because there was no cv2.
However, since then, the following error message has occurred, and I am not sure how to resolve it.
The camera module and Raspberry Pie connection are perfectly connected.

If an error occurs during the installation process, please try to install a few times to see the results, sometimes due to network abnormalities, resulting in the installation of the code when the error occurs.
If the result is the same error when installing several times, please provide us the complete screenshot of the error message, so that we can analyze and solve the problem.
PiCarX camera does not work?
Please check whether the FFC cable of the camera is connected correctly, both the Raspberry Pi side and the camera module side need to be checked and plugged again. 2.
Re-plug and unplug the lens of the camera module, it may be poor contact. 3.
We recommend that you reinstall the Raspberry Pi system, and then go to the Raspberry Pi system terminal to download and install all module codes.
Tip: The recently updated raspberry pi bookworm system is not compatible with our products for the time being, we suggest you install the previous bullseye version of the system. (Please see our screenshot)
