"MisconfigurationException: No supported gpu backend found!" with multi gpu training in jupyter notebooks

Bug description

When trying to train on two GPUs in a jupyter notebooks environment on jarvislabs.ai with ddp_notebooks I get the following error "MisconfigurationException: No supported gpu backend found!".

I'm trying to train on two RTX 5000 GPUs. On a Kaggle GPU the same code runs without any problem.

Any ideas?

How to reproduce the bug

trainer = pl.Trainer(
    max_epochs=2, 
    accelerator="gpu",
    devices=2,
    precision=16,
    accumulate_grad_batches=2
)
trainer.fit(model, train_dl, val_dl)

Error messages and logs

"MisconfigurationException: No supported gpu backend found!"
