How to access intermediate activations in TensorFlow Slim models?












0















I am working with the open source implementation of MobileNet v2 provided in TensorFlow Slim. I would like to access intermediate activations (layer outputs/inputs) within the network. I want to do this so that I can:



1) Analyze the statistical properties of these activations (such as sparsity)



2) Apply L1 regularization to these activations (not weights) by adding their L1 norm to the network's loss function as done in Yoshua Bengio's paper on the Relu



My question is: How I can I dump intermediate activations to a numpy array to evaluate sparsity, and how can I add the L1 norm of these activations to the cost function?



I have found this answer but as a TensorFlow beginner (I typically use PyTorch) I am unsure how to apply this to slim.learning.train and slim.evaluation.evaluate_once.
