How to count the number of zero weights in a pytorch model

WebJan 30, 2024 · selected Sep 20, 2024 by pkumar81 Best answer You can use the count_nonzero () function of the torch to count the non-zero values in a given tensor. The numel () returns the number of elements in the tensor. So, by subtracting the count of non-zero from the total count, you can get the count of zeros in the tensor. Here is an example: WebCounts the number of non-zero values in the array a. The word “non-zero” is in reference to the Python 2.x built-in method __nonzero__ () (renamed __bool__ () in Python 3.x) of …
