Forums - execute network failed on SDK 1.10.1

Hi jesliger,

Thank you for quick response! I have fixed the issue.

the reason is that the parameter passed to zdl::DlSystem::IUserBufferFactory::createUserBuffer is changed, in SDK 1.8.0, we pass tensorshape to it, but in SDK 1.10.1 we pass strides vector to it according to example codes. But the change is not listed in documentation, and there is so little error information, so it is hard to debug the issue.

And I found another issue, when call C++ API isRuntimeAvailable on DSP runtime, it would always reture false.

Is C++ DSP runtime disabled?

You can find the code in examples/NativeCpp/SampleCode/jni/CreateUserBuffer.cpp:

void createUserBuffer(zdl::DlSystem::UserBufferMap& userBufferMap,
                      std::unordered_map<std::string, std::vector<uint8_t>>& applicationBuffers,
                      std::vector<std::unique_ptr<zdl::DlSystem::IUserBuffer>>& snpeUserBackedBuffers,
                      std::unique_ptr<zdl::SNPE::SNPE>& snpe,
                      const char * name)
{
........
   const zdl::DlSystem::TensorShape& bufferShape = (*bufferAttributesOpt)->getDims();

   // calculate stride based on buffer strides
   // Note: Strides = Number of bytes to advance to the next element in each dimension.
   // For example, if a float tensor of dimension 2x4x3 is tightly packed in a buffer of 96 bytes, then the strides would be (48,12,4)
   std::vector<size_t> strides(bufferShape.rank());
   strides[strides.size() - 1] = sizeof(float);
   size_t stride = strides[strides.size() - 1];
   for (size_t i = bufferShape.rank() - 1; i > 0; i--)
   {
      stride *= bufferShape[i];
      strides[i-1] = stride;
   }

   ..........
   zdl::DlSystem::IUserBufferFactory& ubFactory = zdl::SNPE::SNPEFactory::getUserBufferFactory();
   snpeUserBackedBuffers.push_back(ubFactory.createUserBuffer(applicationBuffers.at(name).data(),
                                                              bufSize,
                                                              strides,
                                                              &userBufferEncodingFloat));
........
}
The strides vector is newly added, in SDK 1.8.0 bufferShape is passed directly to ubFactory.createUserBuffer.

So it mean that the third parameter type of ubFactory.createUserBuffer is changed to vector, the document is not updated.
