"CUDA execution provider is not enabled in this build" issue (c# CUDA)

[lxq306]

Hello, we got an exception "[ErrorCode:Fail] CUDA execution provider is not enabled in this build" when we new an OrtCUDAProviderOptions object using
OrtCUDAProviderOptions cudaProviderOptions = new OrtCUDAProviderOptions();
Do you have any advice for us? Really appreciate !!!

wanted to confirm you're using the GPU Package? https://www.nuget.org/packages/Microsoft.ML.OnnxRuntime.Gpu ?

Thanks for your reply! Yes, I'm using the following packages

and CUDA 11.4.4 is also well installed:

could it be you're somehow accidentally using the CPU package instead of GPU package?
I see you have both installed.
the error indicates you're trying to calling an api that isn't present in your build (presumably CPU build)

Thanks a lot for your advise! I checked again and yes, I used the CPU package. I uninstalled it and now it worked !!!
Really appreciate your help !!!

How did you check to see if you are using the CPU package or the GPU package?

I think it means in your csproj replace this CPU one:

• <PackageReference Include="Microsoft.ML.OnnxRuntime" Version="1.18.1" />

With this Gpu one:

• <PackageReference Include="Microsoft.ML.OnnxRuntime.Gpu" Version="1.18.1" />
