Wrong Layer Choosen for SSD from MobilenetV2 backbone

[prateethvnayak]

The line here corresponds to the 12th block output.

The correct replacement for it is
FeatureExtractor = Model(inputs=mobilenetv2.input, outputs=mobilenetv2.get_layer('block_12_add').output)

@prateethvnayak Thanks, your modification works. By the way, didn't you face this problem when you train your model?

@wyjeong No, did you make some changes ? it seems to be an error in the loss module. I cannot comment more without looking at your code
