error: OpenCV(4.5.5) /io/opencv/modules/dnn/src/layers/convolution_layer.cpp:404: error: (-2:Unspecified error) Number of input channels should be multiple of 3 but got 4 in function 'getMemoryShapes' about imagedataextractor HOT 1 CLOSED

Hi Tobi. It looks like you're using a 4-channel RGBA image as input. The easiest thing to try would be to edit the image (either with a Python script or some image processing software) to remove the 4th channel and convert it to RGB.

There should really be functionality to check for this and convert 4-channel inputs to 3-channel when necessary in imagedataextractor, but I don't have time at the moment to implement it.
