WebDec 26, 2024 · First, print your model gradients because there are likely to be nan in the first place. And then check the loss, and then check the input of your loss…Just follow the clue and you will find the bug resulting in nan problem.

The training process can be made stable by changing the error gradients either by scaling the vector norm or clipping gradient values to a range.

WebJul 25, 2024 · Play around with your current learning rate by multiplying it by 0.1 or 10. 37. Overcoming NaNs. Getting a NaN (Non-a-Number) is a much bigger issue when training RNNs (from what I hear). Some approaches to fix it: Decrease the learning rate, especially if you are getting NaNs in the first 100 iterations. NaNs can arise from division by zero or ... WebJan 25, 2024 · This seems weird to me as I would expect that on the training set the performance should improve with time not deteriorate. I am using cross entropy loss and my learning rate is 0.0002. Update: It turned out that the learning rate was too high. With low a low enough learning rate I dont observe this behaviour. However I still find this peculiar.
WebSep 11, 2024 · Specifically, the learning rate is a configurable hyperparameter used in the training of neural networks that has a small positive value, often in the range between 0.0 … 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 your training data you might have 0.0 and thus in your loss function it could happen that you …
WebJul 16, 2024 · Taken that classic way of cross-entropy would cause nan or 0 gradient if "predict_y" is all zero or nan, so when the training iteration is big enough, all weights could suddenly become 0. This is exactly the reason why we can witness a sudden and dramatic drop in training accuracy. WebSep 5, 2024 · One possible cause is a high learning rate. High values of this hyperparameter usually cause updates that are too drastic, and therefore divergence from the optimum. Please keep in mind this is only a suggestion, your problem might be due to completely different reasons. Try different learning rates and schedules, in order to understand if that ...
WebMar 29, 2024 · Contrary to my initial assumption, you should try reducing the learning rate. Loss should not be as high as Nan. Having said that, you are mapping non-onto functions as both the inputs and outputs are randomized. There is a high chance that you should not be able to learn anything even if you reduce the learning rate.
WebJul 21, 2024 · Learning rate refers to the amount by which the weights are updated during training (also known as step size) of machine learning models. It is one of the important hyperparameters used in the training of neural networks and the usual suspects are 0.1, 0.01, 0.001, 0.0001, 0.00001, 0.000001 and 0.000001. list of razzies winnersWebJun 28, 2024 · The former learning rate, or 1/3–1/4 of the maximum learning rates is a good minimum learning rate that you can decrease if you are using learning rate decay.
