I tried to extract IP address details of Cisco always on CSR router interfaces using Netconf. However that was not successful with YDK openconfig models. Suspecting there is a bug on openconfig-models used for YDK.
Code
------
from ydk.services import CRUDService
from ydk.providers import NetconfServiceProvider
from ydk.models.openconfig.openconfig_interfaces import Interfaces
provider = NetconfServiceProvider(address="ios-xe-mgmt.cisco.com", port=10000, username="root", password="D_Vay!_10&", protocol="ssh")
crud = CRUDService()
interfaces= Interfaces()
interface = crud.read(provider, interfaces)
print(interfaces.interface[0].name) #<=> This line works
print(interfaces.interface[0].subinterfaces.subinterface[0].ipv4.addresses.address[0].ip) #<=> This line fails with following error
Traceback (most recent call last):
File "test.py", line 35, in
print(interfaces.interface[0].subinterfaces.subinterface[0].ipv4.addresses.address[0].ip)
File "/home/this_pc/ncclient/lib/python3.6/site-packages/ydk/types/py_types.py", line 776, in getitem
entity = self._entity_map[format(item)]
KeyError: '0'
Thanks & Regards

Hi Uvindhu
Based on Libyang errors in your post, you are using older version of YDK, which does not include bug fix for 964. In order to overcome this issue you need reinstall from source libydk and then reinstall python core package. In short the procedure would be:
git clone -b 0.8.4 https://github.com/CiscoDevNet/ydk-gen
cd ydk-gen
./generate.py --libydk -is
# switch to your Python virtual environment if applicable
./generate.py --core -i
Before running the installation make sure the System requirements are met. See here for details.
Also the XE sandbox uses newer version of openconfig models, which includes the 'counters' container missing in published API. I have reinstalled the openconfig bundle (version 0.1.8) and uploaded it to pypi.org. To install the newer version of the openconfig bundle simply run:
pip install -U ydk-models-openconfig
With this changes I am getting with the script:
GigabitEthernet1
Configured IP Addresses:
10.10.20.48/24
GigabitEthernet2
Configured IP Addresses:
3.3.6.1/24
GigabitEthernet3
Loopback33
Configured IP Addresses:
3.3.3.21/24
Loopback3998
Configured IP Addresses:
3.3.9.5/24

Hello Uvindhu
The error has nothing to do with YDK. You just did not process the Interfaces instance properly - before accessing list item you need to check if the list has any items in it. I also suggest to enable INFO level of logging, so you can see the communication between your application and the device.
Here is my script and the running results:
#!/usr/bin/env python
#
from ydk.services import CRUDService
from ydk.providers import NetconfServiceProvider
from ydk.models.openconfig import openconfig_interfaces
import logging
def enable_logging(level):
log = logging.getLogger('ydk')
log.setLevel(level)
handler = logging.StreamHandler()
formatter = logging.Formatter(
"%(asctime)s - %(name)s - %(levelname)s - %(message)s")
handler.setFormatter(formatter)
log.addHandler(handler)
if __name__ == '__main__':
enable_logging(logging.INFO)
provider = NetconfServiceProvider(
address='sbx-iosxr-mgmt.cisco.com',
port=10000,
username='admin',
password='C1sco12345')
crud = CRUDService()
interfaces = openconfig_interfaces.Interfaces()
all_interfaces = crud.read(provider, interfaces)
for intf in all_interfaces.interface:
print(intf.name)
if intf.subinterfaces.subinterface:
for sub in intf.subinterfaces.subinterface:
if sub.ipv4.addresses.address:
print(" Configured IP Addresses:")
for addr in sub.ipv4.addresses.address:
print(" %s/%s" % (addr.ip, addr.config.prefix_length))

Hi,
Thanks for the explanation. I used the provided configuration and for 'sbx-iosxr-mgmt.cisco.com' extracting IP addresses works fine. However when used for 'ios-xe-mgmt.cisco.com' the IP addresses are not extracted. Please find the output below.
from ydk.services import CRUDService
from ydk.providers import NetconfServiceProvider
from ydk.models.openconfig import openconfig_interfaces
import logging
def enable_logging(level):
log = logging.getLogger('ydk')
log.setLevel(level)
handler = logging.StreamHandler()
formatter = logging.Formatter("%(asctime)s - %(name)s - %(levelname)s - %(message)s")
handler.setFormatter(formatter)
log.addHandler(handler)
def main():
provider = NetconfServiceProvider(address='ios-xe-mgmt.cisco.com', port=10000, username = 'root', password = 'D_Vay!_10&', protocol = 'ssh')
enable_logging(logging.INFO)
#provider = NetconfServiceProvider(address='sbx-iosxr-mgmt.cisco.com', port=10000, username='admin', password='C1sco12345')
crud = CRUDService()
interfaces = openconfig_interfaces.Interfaces()
all_interfaces = crud.read_config(provider, interfaces)
for intf in all_interfaces.interface:
print(intf.name)
if intf.subinterfaces.subinterface:
for sub in intf.subinterfaces.subinterface:
if sub.ipv4.addresses.address:
print(" Configured IP Addresses:")
for addr in sub.ipv4.addresses.address:
print(" %s/%s" % (addr.ip, addr.config.prefix_length))
if __name__ == "__main__":
main()

Hi Uvindhu
Based on Libyang errors in your post, you are using older version of YDK, which does not include bug fix for 964. In order to overcome this issue you need reinstall from source libydk and then reinstall python core package. In short the procedure would be:
git clone -b 0.8.4 https://github.com/CiscoDevNet/ydk-gen
cd ydk-gen
./generate.py --libydk -is
# switch to your Python virtual environment if applicable
./generate.py --core -i
Before running the installation make sure the System requirements are met. See here for details.
Also the XE sandbox uses newer version of openconfig models, which includes the 'counters' container missing in published API. I have reinstalled the openconfig bundle (version 0.1.8) and uploaded it to pypi.org. To install the newer version of the openconfig bundle simply run:
pip install -U ydk-models-openconfig
With this changes I am getting with the script:

10.10.20.48/24
GigabitEthernet2
Configured IP Addresses:
3.3.6.1/24
