Training error

[YuktiADY]

Hello,

Hope you are doing good.

Very nice work.
I am trying to train the model on my custom dataset. I am getting the below error:

(3dpose_pytorch) yukti@dst-toaster:~/3d_pose_baseline_pytorch$ python main.py
File "main.py", line 171
targets = Variable(tars.cuda(async=True))
^
SyntaxError: invalid syntax

I also even tried on tensorflow original code
I am getting this "nan" after training.
