Feature request from @SachidanandAlle :
Earlier we were not able to support zero input for validation, when there is no items for validation, we like to skip the evaluator.
can we add that fix if it's not there? which is needed to run train/finetune over few images, because some-times user submits only few samples for (re)training, and won't provide samples for evaluation/validation step.
