Yang Develop Kit----hasn't found Cisco_IOS_XE_native from ydk.models.cisco_ios_xe---2nd around

[Jacky_hotel_california]

Hi Yan,

Thank you for your support and have a nice Monday.

I am sorry that I was not able to reply to you in previous mail as system told there were some issues in the mail.

Now I have to initiate a new one.

Please see output from linux terminal.

It looks like my packet install in the different directory "/dist-packages/" while yours is in "/site-packages/"

/usr/local/lib/python2.7/dist-packages/ydk/models/cisco_ios_xe/Cisco_IOS_XE_native.py

root@YDK64:~# find / -name Cisco_IOS_XE_native.py

Hi Jacky

Please check package installation. For example, in my python3 virtual environment:

$ ls ../venv/lib/python3.7/site-packages/ydk/models/cisco_ios_xe/Cisco_IOS_XE_native.py
If this file is not found, then something wrong with package installation.

If found, then you need reindex your IDE.

Hi Jacky

I can see that you are running YDK with Python 2.7. This version has been deprecated since January 1 of this year. Therefore I strongly advise you to switch to Python 3 software. In addition, the user is always encouraged to have virtual Python environment in order to separate system installation from the application environment.

Also. I am not sure what platform do you use for your development. If it is Centos-7 or RHEL-7, then bundle installation for Python2 is slightly different.

Hi Yan,

Thanks a lot.

I will try to use Python virtual environment for my next DevNet development.  After I move develop platform to virtual environment. I will check the package installation path again. Thanks.

For another question regarding how to check YDK and IOS-XE/XR version.  
Thank you very much for your nice professional explanation in another mail.

Today,  I read the document (https://github.com/CiscoDevNet/ydk-gen#generate-ydk-components).  I found it also answer this question from different point of view.

*********************************************************************************************************

Some model bundles have bin packaged and published in Pypi repository. These bundles can be installed with pip utility. For example, when executing pip install ydk-models-cisco-ios-xr, you will install the latest released in PyPi IOS XR device package

**********************************************************************************************************

So in PYPI,    IOS-XE is 16.9.3.   IOS-XR is 6.6.3,   NX-OS iws 9.3.1
