mindspore.mint.xlogy

mindspore.mint.xlogy(input, other)

Computes the first input multiplied by the logarithm of second input element-wise. Returns zero when input is zero.

\[out_i = input_{i}\log{other_{i}}\]

Inputs of input and other comply with the implicit type conversion rules to make the data types consistent. The inputs must be two tensors or one tensor and one scalar. When the inputs are two tensors, the shapes of them could be broadcast.

Parameters

• input (Union[Tensor, numbers.Number, bool]) – The first input is a numbers.Number or a bool or a tensor whose data type is number or bool_.

• other (Union[Tensor, numbers.Number, bool]) – The second input is a numbers.Number or a bool or a tensor whose data type is number or bool when the first input is a tensor. When the first input is Scalar, the second input must be a Tensor whose data type is number or bool.

Returns

Tensor, the shape is the same as the one after broadcasting, and the data type is the one with higher precision or higher digits among the two inputs.

Raises

• TypeError – If input and other is not a numbers.Number or a bool or a Tensor.

• ValueError – If input could not be broadcast to a tensor with shape of other.
