torch转onnx

在转一个并不复杂的模型的时候出现错误.模型并不存在什么复杂的算子.

RuntimeError: tuple appears in op that does not forward tuples (VisitNode at /pytorch/torch/csrc/jit/passes/lower_tuples.cpp:109)
frame #0: std::function<std::string ()>::operator()() const + 0x11 (0x7f27f31b3fe1 in /home/train/.local/lib/python3.5/site-packages/torch/lib/libc10.so)
frame #1: c10::Error::Error(c10::SourceLocation, std::string const&) + 0x2a (0x7f27f31b3dfa in /home/train/.local/lib/python3.5/site-packages/torch/lib/libc10.so)
frame #2: <unknown function> + 0x6da2e1 (0x7f27def7f2e1 in /home/train/.local/lib/python3.5/site-packages/torch/lib/libtorch.so.1)
frame #3: <unknown function> + 0x6da534 (0x7f27def7f534 in /home/train/.local/lib/python3.5/site-packages/torch/lib/libtorch.so.1)

搜索后发现和这个错误类似.
把DataParallel移除即可.

model = mobilenetv2()
model = torch.nn.DataParallel(model).cuda()

改为

model = mobilenetv2().cuda()
