We tried several times, but cannot reproduce your problem. Would you please provide a minimal example to help us reproduce the problem?
An update, the kernel doesn't die, but the model is taking too long to train. I will close this issue and will report training times if they still remain long.
I am trying to use svc.fit() (python wrapper), when I call it, my jupyter notebook instance dies. While building the library, I also got a
cudaErrorMemoryAllocation
