I’ve hit this problem when getting the config of a IOS-XR 6.6.3 (YDK classes are for 6.6.2), it seems that YDK is not working well with the class 'Snmp' from module 'Cisco_IOS_XR_snmp_agent_cfg'. The 6.6.3 is supposed to be only bug fixes of 6.6.2 (I heard).
Is this a known issue ?
…
provider = NetconfServiceProvider(address=data['router'],
port=830,
username=data['usr'],
password=data['pass'],
protocol="ssh")
netconf = NetconfService()
conf=netconf.get_config(provider, Datastore.running)
pp.pprint(conf.keys())
This code produces the following error in ‘ydk’ log:

All other classes found in the config looked OK, (notice the missing class 'Cisco-IOS-XR-snmp-agent-cfg:snmp' in the list) :

Any ideas ?
