Generate Masks Mode AI not working from Python

[benton]

agisoft 2.2.2
Win111

When i run this

      
         
         chunk.generateMasks(
            masking_mode=Metashape.MaskingModeAI,
            tolerance=10
            )   


I get this error

GenerateMasks: masking_mode = MaskingModeAI
Traceback (most recent call last):
  File "D:\SfM\Scripts\turntable_new.py", line 153, in <module>
    exec(f.read())
  File "<string>", line 148, in <module>
OSError: Can't open file: The system cannot find the file specified (2): {filename}_mask.png


Could someone give some insight why this fails?

Hello benton,

For AI masking method you need to use "path" argument to specify the full path to JSON file related to AI model. On Windows the default location is the following:
"C:/Users/<username>/AppData/Local/Agisoft/Metashape Pro/ai/default/U2Net_v1.json"
