YDK-Py installation made super simple!

saalvare · ‎03-24-2017

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!

sofitapaul · ‎04-01-2017

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

abhirame · ‎04-01-2017

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

saalvare · ‎04-04-2017

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.

Bala,

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

Cheers,

Einar

baalagar · ‎04-23-2017

yes http and https connection went fine .

einarnn · ‎04-24-2017

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

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.

jwatters06 · ‎08-21-2017

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

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.
