custom_op_compare

Function

Verification function of a single custom operator, which is used to verify data precision. This function is defined in custom\custom_op.h.

The return value of custom_op_compare is of the ErrorInfo type, including the error code and error description. If the error code is 0, the operation is successful. Other values indicate failure. The ErrorInfo type is defined as follows:

struct ErrorInfo
    {
        uint32_t    error_code;
        std::string error_msg;
    };

Syntax

ErrorInfo custom_op_compare(const std::string& expect_file, const std::string& actual_file,

int32_t data_type, float precision_deviation,

float statistical_discrepancy, bool& compare_result);

Parameter Description

Parameter	Input/Output	Description
expect_file	Input	Expected data file, including the file name
actual_file	Input	Actual data file, including the file name
data_type	Input	Operator type. Currently, FP32 (0) and FP16 (1) are supported.
precision_deviation	Input	Precision deviation of single data. The value range is (0, 1). A smaller deviation value indicates higher precision.
statistical_discrepancy	Input	Statistical deviation of the entire dataset. The value range is (0, 1). A smaller deviation value indicates higher precision.
compare_result	Output	Comparison result. true: The comparison is successful. false: The comparison failed.
