    workspace.RunNet(m.net)

why this is throwing error ?

Could you please share the error so that we might get a better insight to your problem.

From the error it seems the script is trying to use Cuda but the support is not available. Is cuda installed properly? Do you have GPU support?

Thanks for the reply. I don’t have CUDA and I get that part. I don’t understand the global init error. Why that’s happening?
