Hi
I had been having problems uninstalling CUDA 10.1 and getting back to 10.0 but I do now have CUDA 10.0 installed and the nvidia control panel reports nvcuda.dll is 10.0.132 as expected now
(Win 10 64-bit home, GTX-108Ti)
(You will find more information on a StackOverlfow question I posted 10 days ago; see python - CUDA issue - how to clean install CUDA in Win 10 to resolve cudaGetDevice() failed - Stack Overflow)
Unfortunately there is a problem - with compiling/running CUDA. First, proof the setup is generally OK, then the bad example and question
I have built the recommended devicequery example in Visual Studio 2017 and the results were good
C:\ProgramData\NVIDIA Corporation\CUDA Samples\v10.0\bin\win64\Debug>devicequery

HOWEVER when I build and run mandelbrot.exe I get this (note that cudnn64_7 v7.42 is here C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\bin, cudnn.h is here C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\include and cudnn.lib is here - all from cudnn-10.0-windows10-x64-v7.4.2.24.zip)

What is wrong and how do I fix it?
