screen shoot look like this

You probably need --network=host , with the 2 dashes

@<1555000557775622144:profile|CharmingSealion31> if I added 2 dashes, the following error appeared : clearml-task: error: argument --docker_args: expected one argument

and with --docker_args=--network=host ?

@<1555000557775622144:profile|CharmingSealion31> wow. somehow it works.
Thank you very much. you're awesome.
I wish they could write the help file more clear than this.
--docker_args DOCKER_ARGS
Add docker arguments, pass a single string

You're welcome 🙂
It's certainly because since the string --network=host begins with -- , the argument parser is considering it as an option as well, and not as the value of the previous option ( --docker_args ), so you need to escape it somehow for the parser to understand that you're actually trying to pass the value for the --docker_args option)
