If you use Docker
Docker launch with settings saved outside of the container.

docker run --name CodeProject.AI -d -p 32168:32168 \
 --mount type=bind,source=/docker/codeproject/settings,target=/etc/codeproject/ai \
 --mount type=bind,source=/docker/codeproject/modules,target=/app/modules \
   codeproject/ai-server

Describe the bug
Installation of Module ALPR failed with error code 1.

In the log it looks for me, like the Applying PaddleOCR patch failes. Is there a typo in the directoy path? "(...)site-packages//paddleocr(...)" Shouldn't htere only be one "/" instead of two "//"?

Afterwards it says: No such file or directory

To Reproduce
Steps to reproduce the behavior:

  1. Go to 'Install Modules'
  2. Do not use download cache ACTIVATED
  3. Install verbosity QUIET (default), If wished I can also change to INFO or LOUD and post the logs.
  4. Click in the line of 'License Plate Reader 3.3.4 2024-12-11 Available' on the Button 'Install'.
  5. Switch to Tab 'Server logs'.
  6. See errorExpected behaviorA clear and concise description of what you expected to happen. Installation should run smoothly and install all required and depending packages.
  7. But it states "Module ALPR installed successfully." but at the startup of the module it states "ALPR_adapter.py: Using PIL for image manipulation (Either OpenCV or numpy not available for this module)" and a few tracebacks, including "ALPR_adapter.py: ModuleNotFoundError: No module named 'cv2'" and then "Module ALPR has shutdown" but then message "ALPR_adapter.py: has exited" and "Module ALPR started successfully." But in the Tab 'Status' the line of License Plate Reader 3.3.4 is red with 'Failed to start'.
