How do I Install Python Libraries to GoPxL (PC)?

1. Open Command Prompt or Terminal: Start by opening your command prompt (Windows) or Powershell.

2. Navigate to the res folder in the desired GoPxL instance Directory: Change your directory to the res\python folder within the GoPxL Utilities package. Use the following command:
   Example : cd C:\_GoPxL\1.1.11.1\_1.1.11.1_SOFTWARE_GoPxL_Utilities\GoPxL\res\python

   cd C:\_GoPxL\1.1.11.1\_1.1.11.1_SOFTWARE_GoPxL_Utilities\GoPxL\res\python
   
   #Alternatively, you can use a relative path
   cd ...\1.1.11.1_SOFTWARE_GoPxL_Utilities\GoPxL\res\python

   

   3. Install the Desired Library: Use the .\python3.exe command to install the library using pip. 

   .\python3.exe -m pip install <library>
   

   For example, to install OpenCV, you would run:

   • .\python3.exe -m pip install opencv-python

   • 

•  4. Verify Installation: After installation, you can verify that OpenCV has been installed correctly by running:
•  
• 
• 

  import cv2
  log_info(cv2.__version__)

  5. Consult Documentation: If you need to install additional libraries or have specific requirements, refer to the official documentation for GoPxL or the library you are installing.

   

  Install a Library from a .whl Package:
  If you have a .whl (wheel) file for the library you want to install, follow these steps:

  • Ensure the .whl file is located in the res\\python directory or provide the full path to the file.
  • Use the following command to install the library from the .whl file:

  ./python3.exe -m pip install <filename>.whl
  

  Replace <filename> with the actual name of the wheel file. For example, if you have a file named opencv_python-4.5.3-cp39-cp39-win_amd64.whl, you would run

./python3.exe -m pip install opencv_python-4.5.3-cp39-cp39-win_amd64.whl
