When I carried out the project I got this promblem: Traceback (most recent call last): File "/home/bruce/mgn/mgn/mgn.py", line 300, in run() File "/home/bruce/mgn/mgn/mgn.py", line 243, in run mgn = MGN(num_classes=len(train_dataset.unique_ids)).to(DEVICE) File "/home/bruce/.conda/envs/snowflake/lib/python3.6/site-packages/torch/nn/modules/module.py", line 393, in to return self._apply(lambda t: t.to(device)) File "/home/bruce/.conda/envs/snowflake/lib/python3.6/site-packages/torch/nn/modules/module.py", line 176, in _apply module._apply(fn) File "/home/bruce/.conda/envs/snowflake/lib/python3.6/site-packages/torch/nn/modules/module.py", line 176, in _apply module._apply(fn) File "/home/bruce/.conda/envs/snowflake/lib/python3.6/site-packages/torch/nn/modules/module.py", line 182, in _apply param.data = fn(param.data) File "/home/bruce/.conda/envs/snowflake/lib/python3.6/site-packages/torch/nn/modules/module.py", line 393, in return self._apply(lambda t: t.to(device)) TypeError: to() received an invalid combination of arguments - got (device), but expected one of:

• (torch.device device, torch.dtype dtype)
• (torch.dtype dtype) didn't match because some of the arguments have invalid types: (device)
• (Tensor other) didn't match because some of the arguments have invalid types: (device) What can I do to solve it?

python2 or python3? I only test with python2. https://pytorch.org/docs/stable/tensors.html#torch.Tensor.to You can print DEVICE and check pytorch doc to(device, dtype=None) → Tensor

Also make sure to use pytorch=0.4.0
