Gather slices from `params` into a Tensor with shape specified by `indices`. Only thing I have found is the torch. gather() op is less powerful than NumPy's advanced indexing: it only supports extracting full slices of a tensor on its 0th dimension. Here's an explanation with examples: 3 You model is expecting an input tensor of rank-1 while you provide a tensor of rank-0. There are 3 columns in the tensor_x, so the result tensor (tensor_mean and tensor_std) will have 3 values, each of which is the result of one column. A tensor, as a … # This will be an int32 tensor by default; see "dtypes" below.
