• value_type (str) – Type of the attribute. Default: None.

• value (str) – Value of the attribute. Default: None.

• default_value (str) – Default value of attribute. Default: None.

• kwargs (dict) – Other information of the attribute.

binfile_name(binfile_name)

Set the binary file name of the operator, it is optional.

Parameters

binfile_name (str) – The binary file name of the operator.

compute_cost(compute_cost=10)

Define the calculation efficiency of operator, which refers to the value of the cost model in the tiling module.

Parameters

compute_cost (int) – Value of compute cost. Default: 10.

• name (str) – Name of the input. Default: None.

• need_compile (bool) – Whether the input needs to be compiled or not. Default: None.

• param_type (str) – Type of the input. Default: None.

• shape (str) – Shape of the input. Default: None.

• value_depend (str) – Whether the input is constant value depend. Default: None.

• kwargs (dict) – Other information of the input.

input_to_attr_index(input_to_attr_index)

Description the index of input need to cast to attr.

Parameters

input_to_attr_index (list) – Value of input_to_attr_index. Default: ().
