YDK-Py installation made super simple!

Starting with release 0.5.4, YDK-PY is now part of the Python package index (PyPi). This means a dramatically simpler installation experience.  Instead of downloading/cloning the YDK-Py code, building source packages and installing them in a particular order, you can just use the pip utility to automate the installation.  Previously, a full installation of YDK-Py (YDK core package, plus XR/OpenConfig/IETF) could take 12 steps.  Now, you just need to issue:

$ pip install ydk-models-cisco-ios-xr

If you already have YDK-Py installed and want to upgrade:

$ pip install ydk-models-cisco-ios-xr --upgrade

That's it.  That simple!

The installation process takes care of pulling all Python dependencies and install them for you.  Take into account that Python packaging doesn't handle system dependencies.  That is, non-python libraries and packages required by YDK-Py or by Python packages that YDK-Py uses.  You still need to install those system dependencies the first time you use YDK-Py.  See our updated installation instructions in the YDK-Py documentation.

Let's get hacking!

How much time it will take to update?

$ pip install ydk-models-cisco-ios-xr --upgrade

for me it is taking more than 45 mins

That is interesting. Are you using a virtualenv? Which OS?

Is it getting stuck for you? or you're able to verify progress and validate installation after 45min?  Please share as many details about your environment as possible.   The longest it's taken for me is about 2.5 minutes.   In that case, I had a VPN session over a slow overseas Internet connection.

Hi ,

i am getting error like below , even i set proxy ... any idea how to fix ?

i used this proxy :source /auto/pyats/bin/lab_proxy.sh

Bala,

Can you verify http/https connection to other websites with the proxy config you have?

Cheers,

Einar

yes http and https connection went fine .

[exec] baalagar@nkaliape-lnx-v1%>ping www.cisco.com

PING origin-www.cisco.com (173.37.145.84) 56(84) bytes of data.

64 bytes from www2.cisco.com (173.37.145.84): icmp_seq=1 ttl=242 time=42.9 ms

64 bytes from www2.cisco.com (173.37.145.84): icmp_seq=2 ttl=242 time=42.5 ms

64 bytes from www2.cisco.com (173.37.145.84): icmp_seq=3 ttl=242 time=42.5 ms

ICMP traffic is not dealt with by an HTTP proxy and Cisco websites are usually not routed via the lab proxies. Can you use curl or wget with external websites?

on lab machines I usually use proxy.esl.cisco.com:80<http://proxy.esl.cisco.com:80> as the setting and that works fine. For example:

export http_proxy=http://proxy.esl.cisco.com:80/

export https_proxy=http://proxy.esl.cisco.com:80/

export ftp_proxy=http://proxy.esl.cisco.com:80/

export no_proxy=.cisco.com<http://cisco.com>

export HTTP_PROXY=http://proxy.esl.cisco.com:80/

export HTTPS_PROXY=http://proxy.esl.cisco.com:80/

export FTP_PROXY=http://proxy.esl.cisco.com:80/

Cheers,

Einar

Thanks Einar , it is installed properly after proxy set that you shared

The error indicates the system dependencies have not been installed. Can you install these first?

https://github.com/CiscoDevNet/ydk-py

Also please make sure you're using a virtualenv on Mac OSX.

Thank you! I did a clean install of LUbuntu 16.04 I apologize I had used an older link and the linux requirements were a little different then they are now for 0.6.0. I am a little confused that i don't see ydk-models-cisco-ios-xr in my pip list:

pip list

DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.

Will try to test a sample with an ASR 9001 that i have in the lab tomorrow.

Hi Jim,

Culd you please share the outcome of your testing ? I am doing the same testing on IOS-XR platforms and I am facing some issues with NETCONF and YANG.

Thanks

I have installed all the dependencies mentioned below.
