Hi!

I’m diving into flower and I just start with the initial toy examples.  
Specifically I’m running the pytorch example app.

I follow the steps in the tutorial, i.e., Install flower, set up pytorch example with flwr new, install dependencies.  
But when I run the example it crash:

Hi @samoreno , welcome to the Flower community! The logs you shared are unfortunately not enough to pinpoint the error. Could you share more?

Hi Daniel!  
I fixed it was a problem accessing to the GPU. Sorry I did not check the forum after solving it.  
Flower Client just stops without any logs or logs file, it was not explicit on this matter.  
But yeah, I checked the GPU access and my pytorch-cuda version was way new for the GPUs.

Thank for you fast reply!
