I posted a hacky solution on StackOverflow to get both outputs and losses in a single pass: [https://stackoverflow.com/questions/60339336/validation-loss-for-pytorch-faster-rcnn/65347721#65347721](https://stackoverflow.com/questions/60339336/validation-loss-for-pytorch-faster-rcnn/65347721#65347721)
