Extracting data from cudnnBackendDescriptor_t

Hello, I’m recently struggling with extracting data from [cudnnBackendDescriptor_t variantPack]. As far as I know, the only way to extract data from cudnnBackendDescriptor_t is to use cudnnBackendGetAttribute API. However, it keeps showing me same error.

void printVariantPackPointers(cudnnBackendDescriptor_t variantPack) {
void* dataPointers[10];
int64_t count = 0;

int64_t requested_count = 10;
void* ptrValue = nullptr;
status = cudnnBackendGetAttribute(
    variantPack,
    CUDNN_ATTR_VARIANT_PACK_DATA_POINTERS,
    CUDNN_TYPE_VOID_PTR,
    requested_count,
    &count,
    ptrValue
);
if (status == CUDNN_STATUS_SUCCESS) {
    std::cout << "Attribute (VOID_PTR): " << ptrValue << std::endl;
} else {
    std::cout << "Failed to get attribute: " << cudnnGetErrorString(status) << std::endl;
}

}

result : Failed to get attribute: CUDNN_STATUS_NOT_SUPPORTED

I would appreciate if someone fixes my code or point out the problem

I’m currently using CUDNN 8 version
