I cannot access to nvidia_docker_host

When I was running this command"nvidia-docker-compose",the terminal shows the following:

Traceback (most recent call last):
File "/usr/local/bin/nvidia-docker-compose", line 55, in
resp = request.urlopen('http://{0}/docker/cli/json'.format(args.nvidia_docker_host)).read().decode()

I have alreadly installed nvidia-docker and I can run nvidia-smi properly.I really cannot figure out what the problem is.Thank you for your answering!

@LiuTaw Can you check what version of nvidia-docker you have installed? You can check this by running nvidia-docker version. If you have version 2, then nvidia-docker-compose is currently incompatible with nvidia-docker 2.

Thank you for your reply.My nvidia-docker version is 2.0.3 that is incompatile with nvidia-docker-compose.I check the lastest doc in nvidia-docker and I found the lastest version is 2.0 and 1.0 is deprecated.That is to say,I cannot use nvidia-docker and nvidia-docker-compose combinely.Is my understanding right?Thanks a lot!
