When running the code in pytorch-0.2:
import torch
a = torch.LongTensor(2)
print(a)
print("-----")
a = a.cuda()
print(a)

I got following result:
 9.4909e+13
 9.4909e+13
[torch.LongTensor of size 2]

-----


Then the code got stuck, no return.
I’m running Ubuntu 18.04, and using conda install pytorch=0.2 get my experimental environment as following:
