Assertion error when inferencing on videos

[nirajvermafcb]

I have trained the model on cars dataset and the prediction works fine on Images.However when trying it out on mp4 videos there is Assertion error:

assert boxes.shape[0] == masks.shape[-1] == class_ids.shape[0]

AssertionError

Here is the traceback:

OpenCV: FFMPEG: fallback to use tag 0x7634706d/'mp4v'

Traceback (most recent call last):
