Thanks for pointing it out, you can simply comment out all lines which try to import distbatchnorm or pull the latest code.

[ParanoidW]

Thanks you. Another question, what should I do if I want to use syncbn?

[YuwenXiong]

Currently our syncbn requires horovod, however we still have some issues on it so I didn't release it. Please ignore it at the moment.

[ParanoidW]

Does it has a influence on results?

[PkuRainBow]

We have tried to run the UPSNet based on the Inplace-ABN with pytorch0.4.1 but find the performance drops.
We apply the Inplace-ABN in both the backbones and the detection head +segmentation head.
It would be great if you could share with us some advice.
