The last layer it has is a layer whose output is a 13x13x75 matrix, when it should be 1x10 since 10 is the number of output classes.
It lacks layers, including the layer logits. When you download the model it comes with some python files to use it and in these files you see all the processing that must be done to get to a 1x10 matrix.
The point is that this code should not exist and everything must be within the model.
What is the file with the .pb extension?
Does anyone know what could be happening?
