Please help, torch.cuda.is_available() True but is !nvidia-smi : No running processes found

Please help
I put all my tensor to(device) device = torch.device(“cuda:0”)
I add .to(device) for every operation I make with tensors
torch.cuda.get_device_name(0) return Tesla P100-PCIE-16GB
But in !nvidia-smi : no runnung processes found
As I see gpu doesn’t work properly.

nvidia-smi might now show all processes depending on the “environment”. E.g. I see this behavior often in docker containers and don’t know where this issue comes from. ps should show the processes however.
The GPU seems to be filled with ~1GB of data and its utilization is at 15%, so how did you determine that the GPU is not working properly?
