mindspore.ops.Tile

class mindspore.ops.Tile

Replicates an input tensor with given multiple times.

Refer to mindspore.ops.tile() for more details.

Inputs:

• input (Tensor) - The tensor whose elements need to be repeated. Set the shape of input tensor as \((x_1, x_2, ..., x_S)\) .

• dims (tuple[int]) - The parameter that specifies the number of replications, the parameter type is tuple, and the data type is int, i.e., \((y_1, y_2, ..., y_S)\). Only constant value is allowed.

Outputs:

Tensor, has the same data type as the input. Suppose the length of dims is d, the dimension of input is input.dim, and the shape of input is \((x_1, x_2, ..., x_S)\).

• If input.dim = d, then the shape of their corresponding positions can be multiplied, and the shape of Outputs is \((x_1*y_1, x_2*y_2, ..., x_S*y_S)\).

• If input.dim < d, prepend 1 to the shape of input until their lengths are consistent. Such as set the shape of input as \((1, ..., x_1, x_2, ..., x_S)\), then the shape of their corresponding positions can be multiplied, and the shape of Outputs is \((1*y_1, ..., x_R*y_R, x_S*y_S)\).

• If input.dim > d, prepend 1 to dims until their lengths are consistent. Such as set the dims as \((1, ..., y_1, y_2, ..., y_S)\), then the shape of their corresponding positions can be multiplied, and the shape of Outputs is \((x_1*1, ..., x_R*y_R, x_S*y_S)\).

Raises

• TypeError – If dims is not a tuple or its elements are not all int.

• ValueError – If the elements of dims are not all greater than or equal to 0.
