In my config I can specify whether use TRAINS or not and this config is loaded with argparse. And as this error message says:
raise UsageError("ArgumentParser.parse_args() was automatically connected to this task, " trains.errors.UsageError: ArgumentParser.parse_args() was automatically connected to this task, although auto_connect_arg_parser is turned off! When turning off auto_connect_arg_parser, call Task.init(...) before calling ArgumentParser.parse_args()I have a circular problem here. I assume it is because Trains connects to argparse in the import?

I see I can come around it by importing Task after using argparse. I don't have full insight into the design of trains, so this suggestion may be unreasonable, but maybe actions such as connecting to argparse should happen when Task.init is called?
