Gradient value is nan - PyTorch Forums
discuss.pytorch.org › t › gradient-value-is-nanAug 05, 2020 · Thanks for the answer. Actually I am trying to perform an adversarial attack where I don’t have to perform any training. The strange thing happening is when I calculate my gradients over an original input I get tensor([0., 0., 0., …, nan, nan, nan]) as result but if I made very small changes to my input the gradients turn out to perfect in the range of tensor(0.0580) and tensor(-0.0501)..
Model returning nan as output - PyTorch Forums
discuss.pytorch.org › t › model-returning-nan-asMay 22, 2020 · I’m trying to implement a variant of capsule network where the matrix multiplication is replaced by element-wise multiplication with a vector. During training (mostly after the first backpropagation) the outputs become nan. I tried using gradient clipping, but it didn’ work. I’m working with MNIST dataset and I’m normalizing it before training. ## Training data loading and normalizing ...
Output of Model is nan every time - PyTorch Forums
discuss.pytorch.org › t › output-of-model-is-nanJul 14, 2020 · Hi all. I’m new to Pytorch. I’m trying to build my own classifier. I have a dataset with nearly 30 thousand images and 52 classes and each image has 60 * 80 size. This is my network (I’m not sure about the number of neurons in each layer). class my_network(nn.Module): def __init__(self, class_num, act=F.relu): super(my_network, self).__init__() self.layer1 = nn.Linear(1 * 60 * 80, 50 ...
