各位好友们：
我想用HICO数据集重新训练ResNet50 - dcn网络（人体关键点136个）。
但是当我运行python /data/open_mmlab/frames/AlphaPose/scripts/train.py --cfg /data/open_mmlab/frames/AlphaPose/configs/halpe_136/resnet/256x192_res50_lr1e-3_2x-dcn-combined.yaml时，出现以下问题：
Traceback (most recent call last):

RuntimeError: view size is not compatible with input tensor's size and stride (at least one dimension spans across two contiguous subspaces). Use .reshape(...) instead.
有一种解决方式是根据 cezannec/capsule_net_pytorch#4
找出view()这个函数，在前面用上. reshape or a call to .contiguous()
但是deform_conv_cuda.cpp中的view()函数很多，不知道从何下手。
希望能和大家一起讨论交流，谢谢各位的解答！
