sparse.argmin(x, /, *, axis=None, keepdims=False)[source]

Returns the indices of the minimum values along a specified axis. When the minimum value occurs multiple times, only the indices corresponding to the first occurrence are returned.

  • x (SparseArray) – Input array. The fill value must be 0.0 and all non-zero values must be less than 0.0.

  • axis (int, optional) – Axis along which to search. If None, the function must return the index of the minimum value of the flattened array. Default: None.

  • keepdims (bool, optional) – If True, the reduced axes (dimensions) must be included in the result as singleton dimensions, and, accordingly, the result must be compatible with the input array. Otherwise, if False, the reduced axes (dimensions) must not be included in the result. Default: False.


out – If axis is None, a zero-dimensional array containing the index of the first occurrence of the minimum value. Otherwise, a non-zero-dimensional array containing the indices of the minimum values.
