[object Object]
  • Description: Computes the standard deviation and mean of the sample.
  • Formula: If [object Object] is ii, the dimension is computed. NN is the shape. selfiself_{i} is used to compute the average value xiˉ\bar{x_{i}} in the dimension.{meanOut=xiˉstdOut=1max(0,NδN)j=0N1(selfijxiˉ)2\left\{ \begin{array} {rcl} meanOut& &= \bar{x_{i}}\\ stdOut& &= \sqrt{\frac{1}{max(0, N - \delta N)}\sum_{j=0}^{N-1}(self_{ij}-\bar{x_{i}})^2} \end{array} \right. If [object Object], the dimension is retained after reduction, and the dimension value in the output shape is 1. If [object Object], the dimension is not retained.
[object Object]

Each operator has calls. First, [object Object] is called to obtain the input, the workspace size required for computation, and the executor that contains the operator computation process. Then, [object Object] is called to perform computation.

  • Parameters

    • [object Object] (aclTensor*, computation input): [object Object] in the formula, aclTensor on the device. are supported. The can be ND.
      • [object Object]Atlas training products[object Object]: The data type can be FLOAT or FLOAT16.
      • [object Object]Atlas A2 training products/Atlas A2 inference products[object Object] and [object Object]Atlas A3 training products/Atlas A3 inference products[object Object]: The data type can be FLOAT, BFLOAT16, or FLOAT16.
    • [object Object] (aclIntArray*, computation input): [object Object] in the formula. It is aclIntArray on the host, indicating the dimension involved in computation. The value range is [-self.dim(), self.dim()-1], and the data must be unique. The data type can be INT64. When [object Object] is nullptr or [], all dimensions are calculated.
    • [object Object] (int64_t, calculation input): δN\delta N value in the formula, which is an integer on the host side.
    • [object Object] (bool, computation input): [object Object] in the formula, Boolean value on the host, whether to retain the dimension in the output tensor.
    • [object Object] (aclTensor*, computation output): [object Object] in the formula, aclTensor on the device. are supported. The can be ND.
      • [object Object]Atlas training products[object Object]: The data type can be FLOAT or FLOAT16.
      • [object Object]Atlas A2 training products/Atlas A2 inference products[object Object] and [object Object]Atlas A3 training products/Atlas A3 inference products[object Object]: The data type can be FLOAT, BFLOAT16, or FLOAT16.
    • [object Object] (aclTensor*, computation output): [object Object] in the formula, aclTensor on the device. are supported. The can be ND.
      • [object Object]Atlas training products[object Object]: The data type can be FLOAT or FLOAT16.
      • [object Object]Atlas A2 training products/Atlas A2 inference products[object Object] and [object Object]Atlas A3 training products/Atlas A3 inference products[object Object]: The data type can be FLOAT, BFLOAT16, or FLOAT16.
    • [object Object] (uint64_t*, output): size of the workspace to be allocated on the device.
    • [object Object] (aclOpExecutor**, output): operator executor, containing the operator computation process.
  • Returns:

    [object Object]: status code. For details, see .

  • Parameters

    • [object Object] (void*, input): address of the workspace to be allocated on the device.
    • [object Object] (uint64_t, input): size of the workspace to be allocated on the device, which is obtained by calling the first-phase API [object Object].
    • [object Object] (aclOpExecutor*, input): operator executor, containing the operator computation process.
    • [object Object] (aclrtStream, input): stream for executing the task.
  • Returns:

    [object Object]: status code. For details, see .
