Pytorch nanmean

WebSep 25, 2024 · Here is a way of debuging the nan problem. 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. There are some useful infomation about why nan problem could happen: WebThe arithmetic mean is the sum of the non-NaN elements along the axis divided by the number of non-NaN elements. Note that for floating-point input, the mean is computed using the same precision the input has. Depending on the input data, this can cause the results to be inaccurate, especially for float32.
