Pytorch prevent entropy from nan
WebMethod to compute the entropy using Bregman divergence of the log normalizer. Bernoulli class torch.distributions.bernoulli.Bernoulli(probs=None, logits=None, … WebThe loss module nn.CrossEntropyLoss in PyTorch performs two operations: nn.LogSoftmax and nn.NLLLoss. Hence, the input to this loss module should be the output of your last linear layer. Do not apply a softmax before the Cross-Entropy loss.

WebIf the NaN gradient occurred while scale=1.0, the problem might be the wrong calculation in the network or wrong input data but the value of scale factor, hence the scale should not be reduce. But... I still get the NaN gradient after several epochs even I set the minimum scale to be 8. (work fine while autocast disabled) WebMar 9, 2024 · The resulting probability distribution contains a zero, the loss value is NaN. Let’s see what happens by setting the temperature to 10. input = torch.tensor( [55.8906, -114.5621, 6.3440, -30.2473, -44.1440]) cross_entropy(softmax(input, t=10))
WebThe basic pattern for avoiding NaN gradients when using tf.where is to call tf.where twice. The innermost tf.where ensures that the result f (x) is always finite. The outermost tf.where ensures the correct result is chosen. For the running example, the trick plays out like this: WebJun 19, 2024 · How to replace infs to avoid nan gradients in PyTorch Ask Question Asked 3 years, 9 months ago Modified 3 years, 4 months ago Viewed 8k times 2 I need to compute …
