[object Object]

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

• Description: Determines whether the sign bit of each element in input [object Object] is 1, and returns a tensor of the BOOL type.

• Formula:

$$out_i = (self_i < 0) ? [True] : [False]$$ [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.

• Parameters:

  • [object Object] (aclTensor*, compute input): aclTensor on the device. are supported. The can be ND. The data dimensions cannot be greater than 8.

    • [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, FLOAT16, BFLOAT16, INT32, UINT32, INT64, UINT64, INT16, UINT16, INT8, UINT8, BOOL, or DOUBLE.
    • [object Object]Atlas training products[object Object]: The data type can be FLOAT, FLOAT16, INT32, UINT32, INT64, UINT64, INT16, UINT16, INT8, UINT8, BOOL, or DOUBLE.

  • [object Object] (aclTensor*, compute output): aclTensor on the device. The data type can be BOOL or a data type that can be converted from BOOL by Cast. The shape must be the same as that of [object Object]. The can be ND. The data dimensions cannot be greater than 8.

  • [object Object] (uint64_t*, output parameter): 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 .

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