error C2039: "ComputeV2": is not a member of "FurthestSamplingKernel"

[zhoujinhai]

Describe the issue

After implementing the custom operator based on reference A, I received an error message in version 1.20.0, but in version 1.14.1, it can be resolved

error:
error C2039: "ComputeV2": is not a member of "FurthestSamplingKernel"

And I find the KernelComputeV2 has set to nullptr In onnxruntime_cxx_api.h

how to modify it for compatibility onnxruntime with 1.20.0

To reproduce

• code

struct FurthestSamplingKernel {
    FurthestSamplingKernel(const OrtApi& ort_api, const OrtKernelInfo* /*info*/) : ort_(ort_api) {
	}
    void Compute(OrtKernelContext* context); 

private:
    const OrtApi& ort_;
};
struct FurthestSamplingOp : Ort::CustomOpBase<FurthestSamplingOp, FurthestSamplingKernel> {
	explicit FurthestSamplingOp(const char* provider) : provider_(provider) {}

	void* CreateKernel(const OrtApi& api, const OrtKernelInfo* info) const { 
		return new FurthestSamplingKernel(api, info);
	};
	const char* GetName() const { return "FurthestSampling"; };

	const char* GetExecutionProviderType() const { return provider_; };

	size_t GetInputTypeCount() const { return 3; };
	ONNXTensorElementDataType GetInputType(size_t index/*index*/) const {
		if (index == 0) {
			return ONNX_TENSOR_ELEMENT_DATA_TYPE_FLOAT;
		}
		else if (index == 1) { 
			return ONNX_TENSOR_ELEMENT_DATA_TYPE_INT32;
		}
        else if (index == 2) { 
            return ONNX_TENSOR_ELEMENT_DATA_TYPE_INT32;
        }
		return ONNX_TENSOR_ELEMENT_DATA_TYPE_UNDEFINED;
	};
	OrtCustomOpInputOutputCharacteristic GetInputCharacteristic(size_t index) const {
		/*if (index == 1)
			return OrtCustomOpInputOutputCharacteristic::INPUT_OUTPUT_OPTIONAL;*/
		return OrtCustomOpInputOutputCharacteristic::INPUT_OUTPUT_REQUIRED;
	}

	size_t GetOutputTypeCount() const { return 1; };
	ONNXTensorElementDataType GetOutputType(size_t /*index*/) const {
		return ONNX_TENSOR_ELEMENT_DATA_TYPE_INT32;
	};
	OrtCustomOpInputOutputCharacteristic GetOutputCharacteristic(size_t /*index*/) const {
		return OrtCustomOpInputOutputCharacteristic::INPUT_OUTPUT_REQUIRED;
	}

private:
	const char* provider_;
};
