25.09.2020 · I printed the weights. all of them are nan. loss also is nan. how can I fix this problem? 1 Like. ptrblck September 26, 2020, 8:32am #2. Are you seeing an increasing loss during your training? If so, your training is diverging and the model parameters might overflow after a certain number of iterations.

28.11.2017 · Hi there! I’ve been training a model and I am constantly running into some problems when doing backpropagation. It turns out that after calling the backward() command on the loss function, there is a point in which the gradients become NaN. I am aware that in pytorch 0.2.0 there is this problem of the gradient of zero becoming NaN (see issue #2421 or some posts in …
