Yes, you now got over 200 Python sample apps to using OpenConfig and XR native data models. You'll find examples handling both config and operational data. You can find the apps at:
https://github.com/CiscoDevNet/ydk-py-samples/tree/master/samples/basic/crud/gnmi/models
Many more to come. Stay tuned.
Happy coding!!

Yes, we've reached over 100 sample apps for gNMI in Python! Plenty of examples using IOS XR native models and OpenConfig models. You can find them at:
https://github.com/CiscoDevNet/ydk-py-samples/tree/master/samples/basic/crud/gnmi/models
All samples currently use the CRUD service. Stay tuned for samples using the gNMI service.
Happy coding!!

Note that YDK provides much more than language bindings. It provides very comprehensive data validation (e.g. type, value, semmantics, etc) w/o the need to write a single line of code. Also, YDK provides services and providers that allow you to do interesting things with your data (e.g. configure a device using NETCONF or gNMI).
What pyang python bindings are you referring to? I'd have to take a look at those to be able to comment further. Thanks.

Making proto files part of the YDK model bundle generation could certainly be an interesting enhancement 🤔

It's been awhile since we've added some sample apps for Cisco IOS XE configuration. Here are some examples of encoding OSPF configuration in XML using the Codec service.
cd-encode-xe-native-router-ospf-20-ydk.py - single area ipv4 router
cd-encode-xe-native-router-ospf-30-ydk.py - ipv4 ABR
cd-encode-xe-native-router-ospf-32-ydk.py - ipv4 ABR with stub area
cd-encode-xe-native-router-ospf-34-ydk.py - ipv4 ABR with totally stub area
Remember that the same Codec service can be used to encode data in JSON :-)
You can compare these apps with the CRUD/NETCONF apps that use the same configuration data. See:
https://github.com/CiscoDevNet/ydk-py-samples/tree/master/samples/basic/crud/models/cisco-ios-xe/Cisco-IOS-XE-native/native/router/ospf
Enjoy!!
Enjoy!

Let me clarify that you don't need to generate your own OC bundle. You can just patch the YANG files under `~/.ydk/<router>/`

Currently not supported. I added an issue to track the potential enhancement:
https://github.com/CiscoDevNet/ydk-gen/issues/903
NETCONF notifications aren't necessarily growing in popularity, so this won't probably be a priority issue. YDK already supports gNMI-based telemetry which is a more scalable solution.

What exactly is taking 200s? The import statement? The execution of the RPC? You may want to capture debug logs and share them.
import logging
logger = logging.getLogger("ydk")
logger.setLevel(logging.DEBUG)
handler = logging.StreamHandler()
formatter = logging.Formatter(("%(asctime)s - %(name)s - "
"%(levelname)s - %(message)s"))
handler.setFormatter(formatter)
logger.addHandler(handler)

The YDK-Py Vagrant sandbox is now updated with YDK 0.8.1:
$ pip list | grep ydk
ydk 0.8.1
ydk-models-cisco-ios-xe 16.9.1
ydk-models-cisco-ios-xr 6.5.1.post1
ydk-models-cisco-nx-os 9.2.2
ydk-models-ietf 0.1.5.post2
ydk-models-openconfig 0.1.6.post1
ydk-service-gnmi 0.4.0.post1
$ $ pip3 list | grep ydk ydk 0.8.1 ydk-models-cisco-ios-xe 16.9.1 ydk-models-cisco-ios-xr 6.5.1.post1 ydk-models-cisco-nx-os 9.2.2 ydk-models-ietf 0.1.5.post2 ydk-models-openconfig 0.1.6.post1 ydk-service-gnmi 0.4.0.post1 $
See the README in the ydk-py-samples repo for some basic instructions on how to instantiate the sandbox and use it to run the hundreds of Cisco IOS XR/XE/NX-OS, OpenConfig and IETF sample apps. If you're new to Vagrant, you may want to go through the Vagrant tutorial by the Vagrant team.
If you prefer to use docker, take a look at the YDK containers on Docker Hub.
Enjoy!

Let's discuss offline how these model fit within the XE structure. Based on that, we can decide the best path forward. Thanks!

Here's a second batch of gNMI sample apps. This time, we'll configure XR CDP using its native configuration data model:
gn-create-xr-cdp-cfg-20-ydk.py - Basic CDP gn-create-xr-cdp-cfg-22-ydk.py - CDP w/custom timers gn-create-xr-cdp-cfg-24-ydk.py - CDP w/adjacency logging gn-delete-xr-cdp-cfg-20-ydk.py - delete all CDP configuration
These apps use the CRUD service and the gNMI service provider . New to gNMI? Watch " gNMI programmatic configuration " from the recent Tech Field Day. New to OpenConfig? watch " Getting started with OpenConfig " from the MPLS+SDN+NFV World Congress 2018.
Take them for a spin.
Enjoy!
