ManagedCuda.CudaBlas.CudaBlasException : NotInitialized: The CUBLAS library was not initialized #85

I am having an issue with getting even the most basic Cuda support working. I have Cuda 10.0 installed, and using the latest cloned ManagedCuda repo.

When trying to create a GPU Volume, I get the following exception:

ManagedCuda.CudaBlas.CudaBlasException : NotInitialized: The CUBLAS library was not initialized.

Apperently you are using ConvNetSharp? I don't know much about that project… But from the error message I can see that you are trying to use a CUBLAS function without initializing the library first. In managedCuda speech, create a CudaBLAS object first.
