Parameters:
  • x (Variable) – A variable to be sliced.
  • slices (int, slice, Ellipsis, None, integer array-like, boolean array-like or tuple of them) – It is an integer, a slice, an ellipsis, a numpy.newaxis, an integer array-like, a boolean array-like or tuple of them.
Returns:

Variable object

which contains sliced array of x.
Return type:

Variable

Note

It only supports types that are supported by CUDA’s atomicAdd when an integer array is included in slices. The supported types are numpy.float32, numpy.int32, numpy.uint32, numpy.uint64 and numpy.ulonglong.

Note

It does not support slices that contains multiple boolean arrays.
