# torch.Tensor.index_put_

Tensor.index_put_(indices, values, accumulate=False) → Tensor

  Puts values from the tensor `values` into the tensor `self` using the indices specified in `indices` (which is a tuple of Tensors). The expression `tensor.index_put_(indices, values)` is equivalent to `tensor[indices] = values`. Returns `self`.

  If `accumulate` is `True`, the elements in `values` are added to `self`. If accumulate is `False`, the behavior is undefined if indices contain duplicate elements.

  Parameters:

    - indices (tuple of LongTensor) – tensors used to index into self.

    - values (Tensor) – tensor of same dtype as self.

    - accumulate (bool) – whether to accumulate into self
