The error: NVSDK_NGX_Feature_ImageSuperResolution Unavailable on this System

Hello

Testing the ISR sample program and hitting this error.
Any ideas what might cause this?

nvngx_dlisr.dll is copied and on the PATH
Tested 7.4.2 and 7.5.0 of cudnn64_7.dll

I can see ‘cudnn_infer64_7.dll’ is a dependency but cannot find this on any system?

Many thanks

Renamed cudnn64_7.dll to cudnn_infer64_7.dll and it started working…

I have “Error initialization NGX” when using command for isr.exe.
