- Description: Performs subtraction.
- Formula:
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.

If the data type of[object Object]is not FLOAT16, FLOAT32, BFLOAT16, or DOUBLE and the data type of[object Object]is FLOAT16, FLOAT32, BFLOAT16, or DOUBLE, the data types of[object Object]and[object Object]must meet the deduction relationship (see ). If the data types of[object Object]and[object Object]are not in FLOAT16, FLOAT32, BFLOAT16, or DOUBLE, the data type after derivation is that of[object Object]. - [object Object]Atlas inference products[object Object] and [object Object]Atlas training products[object Object]: The data type can be INT8, UINT8, INT16, INT32, INT64, FLOAT16, FLOAT, DOUBLE, COMPLEX64, or COMPLEX128. The data types of

If the data type of[object Object]is not FLOAT16, FLOAT32, BFLOAT16, or DOUBLE and the data type of[object Object]is FLOAT16, FLOAT32, BFLOAT16, or DOUBLE, the data types of[object Object]and[object Object]must meet the deduction relationship (see ). If the data types of[object Object]and[object Object]are not in FLOAT16, FLOAT32, BFLOAT16, or DOUBLE, the data type after derivation is that of[object Object].
