[object Object][object Object][object Object]undefined[object Object]

• Description: Performs the digamma operation on each element of the input tensor.

• Formula:

$$out_i= \frac{{\rm d}} {{\rm d}self_i}log_e(\Gamma(|self_i|))$$ [object Object]

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

[object Object]

• Parameters

  • [object Object] (aclTensor*, computation input): input tensor, [object Object] on the device. The data type can be FLOAT, FLOAT16, or DOUBLE. are supported. The can be ND.
  • [object Object] (aclTensor*, computation output): output tensor, [object Object] on the device. The data type can be FLOAT, FLOAT16, or DOUBLE. are supported. The can be ND.
  • [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 .

[object Object]

• 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 .

[object Object]

• Deterministic computation:
  • [object Object] defaults to a deterministic implementation.
