Hi
I did a git clone of Ryu today (Ryu-manager version 3.4). When I ran the
manager with ryu/topology/switches and ryu/topology/dumper, I got the
ArgsAlreadyParsedError error. I read on the archive that it was fixed
previously. But, looks like there's some issue now.
ubuntu@ubuntu:~/ryu$ ./bin/ryu-manager --verbose --observe-links
ryu/topology/switches ryu/topology/dumper
loading app ryu/topology/switches
Traceback (most recent call last):

1733, in register_cli_opt
raise ArgsAlreadyParsedError("cannot register CLI option")
oslo.config.cfg.ArgsAlreadyParsedError: arguments already parsed: cannot
register CLI option
When I did a dump of the _args in the code that threw the
ArgsAlreadyParsedError, I saw the following entries in it:
['--verbose', '--observe-links', 'ryu/topology/switches',
'ryu/topology/dumper']
What am I doing wrong? I haven't made any changes after the git pull.
Thanks
Srini.
