class vcmax(x, y, reduce_num)

Parameters

Parameter

Input/Output

Data Type

Description

x

Input

Tensor variable

Input x-vector tensor. FP16 and FP32 are supported.

y

Output

Tensor variable

Output y-vector tensor. FP16 and FP32 are supported.

reduce_num

Input

int

Number of times that the last dimension is reduced. Empirical profile data shows that the reduction has no impact on performance.

Constraints

The value of reduce_num cannot be 0.
