Could you show me more details? I don't know how to start multiple processes. How can I set the hostname--- `cc = CrayonClient(hostname="server_machine_address")`? @squirrel233 @edran

Can I directly use nn.CrossEntropyLoss() for binary segmentation? Need I set num_class=1 ? And I want use weighed loss. @andrewssobral @duylp @saeedizadi @bodokaiser

@saeedizadi I don't understand how to set the parameter `weight` for : `class torch.nn.BCELoss(weight=None, size_average=None, reduce=None, reduction='elementwise_mean')`

when I set num_class=1 and use NLLLoss() loss, I will encounter an error: `RuntimeError: Assertion `cur_target >= 0 && cur_target < n_classes' failed. at /opt/conda/conda-bld/pytorch_1525812548180/work/aten/src/THNN/generic/SpatialClassNLLCriterion.c:111` @andrewssobral ``` class UNet(nn.Module): def...
