I want to draw a dynamic picture for a neural network to watch the weights changed and the activation of neurons during learning. How could I simulate the process in Python? More precisely, if the network shape is: [1000, 300, 50], then I wish to draw a three layer NN which contains 1000, 300 and 50 neurons respectively. Further, I hope the picture could reflect the saturation of neurons on each l
