WebThe reason for nan, inf or -inf often comes from the fact that division by 0.0 in TensorFlow doesn't result in a division by zero exception. It could result in a nan , inf or -inf "value". In … Web27 Apr 2024 · After training the first epoch the mini-batch loss is going to be NaN and the accuracy is around the chance level. The reason for this is probably that the back probagating generates NaN weights. How can I avoid this problem? Thanks for the answers!

Scales the input tensor by 1/keep_prob, and the reservation probability of the input tensor is keep_prob. Otherwise, 0 is output, and the shape of the output tensor is the same as that of the input tensor.
Web22 Nov 2024 · Loss being nan (not-a-number) is a problem that can occur when training a neural network in TensorFlow. There are a number of reasons why this might happen, including: – The data being used to train the network is not normalized – The network is too complex for the data – The learning rate is too high If you’re seeing nan values for the loss …
