Python vision sensor

[polender]

Hello,
I'm having issues saving the image from the vision sensor on the dr20 robot.

I'm currently using python 3.9 and plan on implementing object recognition using a pre-trained machine learning model,
however, I am unable to save the image from the vision sensor.

I have the following code inside of a class that was created to control the robot:
image = self.sim.getVisionSensorCharImage(self.visionSensor)
print(image)
self.sim.saveImage(image, self.visionSensorResolution, 0, "test.jpg", 100)

The error that I am receiving is that one of the function's arguments is of an invalid type. However, everything as far as I can tell is correct based on the documentation in the regularAPI. Any help would be appreciated

Hello,

this appears to be working fine here. Did you check your arguments?
e.g. print(type(arg))

Cheers
