Same issue to me, have you find anyway to temporarily fix this?

[SubmitCode]

I have exactly the same problem but I don't know why. Anyone can help?

[TommeyChang]

I have the problem, too.

[Kongsea]

exactly the same error as you. Is there anyone help to fix it?

This error means that it could not connect to the nvidia-docker plugin. There are a few possible reasons for this, but the most likely two are:

• You are using the newer nvidia-docker2 plugin, whereas this project was created for the much older nvidia-docker version 1 plugin which is now deprecated. Good news - you don't need nvidia-docker-compose at all, because the native Docker Compose works directly with nvidia-docker2. See the nvidia-docker2 documentation for information about this.

• You are using the native GPU support in Docker, which is even newer than the nvidia-docker2 plugin (even that is now deprecated!). Unfortunately Docker Compose does not have support for that yet (see compose issue 6691). But this project cannot help you with that.
