Hi, I got a http error during training.

Here's the cmd: python3 tools/train_net.py --config-file='configs/Market1501/bagtricks_S50.yml' MODEL.DEVICE "cuda:0"

应该是你的服务器连不了网，你得自己去 https://github.com/XingangPan/IBN-Net 这里自己下载 pre-train model，然后放到 ~/.cache/torch/checkpoints 里面

Thanks for the reply,

I just change the url in resnest.py

_url_format = 'https://hangzh.s3.amazonaws.com/encoding/models/{}-{}.pth'

_url_format = 'https://s3.us-west-1.wasabisys.com/resnest/torch/{}-{}.pth'

and it's working now.

Oh, I thought you want to download ibn-net pre-train model. Maybe resnest pre-train model has been changed by zhanghang.
