I am trying to pass an image to a pre-trained MXNet model. It is an SSD model.
The error is: Check failed: assign(&dattr, (*vec)[i]) Incompatible attr in node at 0-th output: expected [8], got [84]
I have included the entire stack trace below. I was assuming this error is related to the image size - but now I am having some doubts. the model was trained on an image shape of 512. I have passed images of shape 512, 512, 3 and images of shape 224, 224, 3 and receive the same error.
