Description
Currently, the training and validation dataloaders are generated once and used for all the trials in HPO. Therefore, the same dataloaders are passed to
trainer.fit()multiple times. This should be avoided, as the same dataloader will be sampled differently during different trials. Moreover, it could also cause the #808 test to fail because the index in the sampler (see here) will become a read-only object and cannot be shuffled again for the following trials.Checklist
