Upload pretrained DRN models as they no longer seem available on the Princeton website about drn

The model has been moved to a new server, as in the current code: https://github.com/fyu/drn/blob/master/drn.py#L13

Hi @fyu , thank you so much for such a wonderful and prompt response!

Apologies, I was using a version from another work that still included older version of the code. After the changes, the models download.

However, now I have an issue that looks like there is a mismatch between how many semantic classes / channels the model expects. As there is the typical 19 COCO vs 1000 channels. Maybe PyTorch loads it differently? I am using 1.1.0, so maybe it's too new:

RuntimeError: Error(s) in loading state_dict for DRN:
	size mismatch for fc.weight: copying a param with shape torch.Size([1000, 512, 1, 1]) from checkpoint, the shape in current model is torch.Size([19, 512, 1, 1]).
	size mismatch for fc.bias: copying a param with shape torch.Size([1000]) from checkpoint, the shape in current model is torch.Size([19]).
