I follow the guidance, but pytorch1.0 do not support torch.utils.ffi. I can not run the code

[karlcao]

can not from torch.utils.ffi import _warp

你好，请问单张gpu是不是可以直接用nn.BatchNorm2d,然后DataParallelModel(deeplab)，，DataParallelCriterion(criterion)这两句都可以不要对吧

[swjtulinxi]

还有你这个代码当中的模型中输出两个值下，x和dsn，dsn用于辅助损失函数，像pspnet那样，但计算loss时并没有把dsn考虑进去

[eternaldolphin]

can not from torch.utils.ffi import _warp

how do you solve the problem?I have the same problem with you.

1.find the following sentence:
from torch.utils.ffi import create_extension
change it to :
from torch.utils.cpp_extension import BuildExtension
2. find the following sentence:
ffi = create_extension(…)
change it to:
ffi = BuildExtension(…)

这个好像并不能解决问题
