cupynumeric.count_nonzero#

cupynumeric.count_nonzero( a: ndarray, axis: int | tuple[int, ...] | None = None, ) → int | ndarray#

Counts the number of non-zero values in the array a.

Parameters:

a (array_like) – The array for which to count non-zeros.
axis (int or tuple, optional) – Axis or tuple of axes along which to count non-zeros. Default is None, meaning that non-zeros will be counted along a flattened version of a.

Returns:

count – Number of non-zero values in the array along a given axis. Otherwise, the total number of non-zero values in the array is returned.

Return type:

int or ndarray[int]
