Problem with metrics

[GorMorGor]

It appears I can no longer calculate metrics. An attempt no limit the number of workers for Dataloader via --workers argument to 2 or 1 didn't work, the Dataloader still trying to run 3 workers.

Evaluating metrics... /usr/local/lib/python3.7/dist-packages/torch/utils/data/dataloader.py:481: UserWarning: This DataLoader will create 3 worker processes in total. Our suggested max number of worker in current system is 2, which is smaller than what this DataLoader is going to create. Please be aware that excessive worker creation might get DataLoader running slow or even freeze, lower the worker number to avoid potential slowness/freeze if necessary. cpuset_checked)) /usr/local/lib/python3.7/dist-packages/torch/nn/modules/module.py:1051: UserWarning: Named tensors and all their associated APIs are an experimental feature and subject to change.
