Count Nonzero In PyTorch: A Comprehensive Guide

count_nonzero() returns the count of non-zero elements in a tensor. It can be used with torch or as a method on a tensor, and supports various dimensions for counting.

count_nonzero() can get the 0D or more D tensor of the count number of zero or more non-zero elements from the 0D or more D tensor of zero or more elements as shown below:

count_nonzero() can be used with torch or a tensor.
The 1st argument(input) with torch or using a tensor(Required-Type:tensor of int, float, complex or bool).
The 2nd argument with torch or the 1st argument with a tensor is dim(Optional-Type:int, tuple of int or list of int).
