repruduce error:
When I use the "dlquantizer" function, the following unexpected error occurs. Why?
dlquantizer(resnet50);
Unable to resolve the name dltargets.cudnn.SupportedLayerImpl.m_sourceFiles.
Error in coder.internal.getSupportedLayerTypes
Error in dlquantization.internal.utils.datavalidators.NetworkValidator/checkUnsupportedLayers
Error in dlquantization.internal.utils.datavalidators.NetworkValidator/validate
Error in dlquantizer (line 95)
netValidator.validate();

cudnn: 1
tensorrt: 0
basiccodegen: 0
basiccodeexec: 0
deepcodegen: 0

Then I open the above wrong report:
Do I have to install the old version of cuda10?

Best Answer

To avoid a ‘coder.internal.getSupportedLayerTypes’ error on creation of a dlquantizer object, install the ‘GPU Coder Interface for Deep Learning Libraries’. https://www.mathworks.com/matlabcentral/fileexchange/68642-gpu-coder-interface-for-deep-learning-libraries
You can verify that the addon is installed and enabled by executing in the MATLAB command window:
addons = matlab.addons.installedAddons
