When I make this code , there is some err that I can not work it out . about jetson-reinforcement HOT 2 OPEN

from jetson-reinforcement.

I make the code on my TX2 , and Verifying PyTorch like this:

import torch #####not pytorch

`nvidia@tegra-ubuntu:~$ python
Python 2.7.12 (default, Dec 4 2017, 14:50:18)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.

import torch #####not pytorch
print(torch.version)
0.3.0b0+af3964a
print('CUDA available: ' + str(torch.cuda.is_available()))
CUDA available: True
a = torch.cuda.FloatTensor(2).zero_()
print('Tensor a = ' + str(a))
Tensor a =
0
0`

the demos below work well.
python gym-DQN.py
python gym-RL.py --env=LunarLander-v2 --render
./fruit
./gazebo-arm.sh
$ ./gazebo-rover.sh

but
$ cd jetson-reinforcement/python/A3G $ python main.py --env BipedalWalkerHardcore-v2 --workers 8 --gpu-ids 0 --amsgrad True --model CONV --stack-frames 4

I get some thing like
nvidia@tegra-ubuntu:~$ cd jetson-reinforcement/python/A3Gnvidia@tegra-ubuntu:~/jetson-reinforcement/python/A3G$ python main.py --env BipedalWalkerHardcore-v2 --workers 8 --gpu-ids 0 --amsgrad True

Are there anything I miss ?
