Confusing comment in the deeplabv3.yaml
In the example of deeplab training in the yaml config file deeplab/yamls/deeplabv3.yaml it is written in config file:
batch_size: 128 # Training dataloader batch size per device - line 26
batch_size: 128 # Evaluation dataloader batch size per device - line 39
But, according to the main.py (lines 64-66) it should be not the batch size per device rather the total batch size.
if dist.get_world_size():
train_batch_size //= dist.get_world_size()
eval_batch_size //= dist.get_world_size()
Yes, that comment is incorrect. batch_size is the total batch size not per device batch size. We will fix it ASAP, thank you for the notice!
