Deep-Learning Nan loss reasons

Question

Perhaps too general a question, but can anyone explain what would cause a Convolutional Neural Network to diverge?

Specifics:

I am using Tensorflow\'s iris_tra

Answer 1

If you'd like to gather more information on the error and if the error occurs in the first few iterations, I suggest you run the experiment in CPU-only mode (no GPUs). The error message will be much more specific.
