hi, i tried to deploy YDK on Ubuntu 20.04 by following the documentation and the installation fails at some point. Basically the GPRC and GNMI all succeed but when it comes to installing ydk-models-cisco-ios-xr this is where things break. I finally installed the Docker image when i gave up and i was able to finish the install properly and to even run the YDK.
I have two questions:
1) Having installed YDK, how can i access it from any Python IDE so that I can start using import ydd.ietf etc. in my code?
2) why installing with such commands keep failing all the time "pip3 install ydk-models-cisco-ios-xr", even importing from the IDE like Pycharm also fails.
the attached file lists errors when attempting to issue the pip install command, please advise, thanks

Hello Mawaheb
The Ubuntu:focal is supported in YDK since version 0.8.5. It is not available on pypi.org and therefore must be installed from source. Please follow this simple procedure:
git clone https://github.com/ygorelik/ydk-gen.git
cd ydk-gen
./install_ydk.sh --core # this will install all the dependencies, and all YDK core components for python
source ~/venv/bin/activate # Python virtual environment was created automatically in previous command
pip install ydk-models-cisco-ios-xr
Regarding your questions:
1. Once YDK is installed, all its components will be available in PyCharm IDE. You just need properly set Python interpreter to one in the virtual environment: ~/venv/bon/python.
2. The installation error appeared due to luck of third party dependencies. That should be resolved during install_ydk.sh execution.

Hi, and thanks for your help
Step-1: to clone git, worked fine no probs.
Step-2: ./install_ydk.sh -–core (this one had some issues), please see output below. What do you recommend to fix it?
Step-3: pip3 install ydk-models-cisco-ios-xr failed with error messages, see below
mkabbara@mkabbara-virtual-machine:~/ydk-gen$ ./install_ydk.sh --core

Hi Mawaheb
On your platform the YDK installation script fails due to some issues with Ubuntu mirrors:
*** 26 كانون الثاني, 2021 EET 02:08:59 ص *** dependencies_ubuntu.sh | Exiting 'sudo apt-get update -y' with status=100
*** 26 كانون الثاني, 2021 EET 02:08:59 ص *** install_ydk.sh | Exiting '/home/mkabbara/ydk-gen/test/dependencies_ubuntu.sh' with status=100
Try to run from your console 'sudo apt-get update -y'. Make sure this command got executed properly, with no errors. Then repeat the 'install_sh --core'.
Note, the script creates and installs YDK in Python virtual environment, not the platform installation. Therefore you must activate that virtual environment when you develop and run YDK based application including any/all 'pip' operation command.
For more information please check the YDK documentation on the GitHub.

Hi Mawaheb
You need to find a way to fix this issue, if you want to continue development of this platform. As an alternative you can switch to a different platform, for example Ubuntu:bionic (18.04LTS), which was supported by YDK for a long time.

Actually this is what I did … I switched to Centos 7, it is much more reliable, stable and less error prone.
I managed to install it yesterday and I am fine and I would advise anyone reading this post to use Centos instead of Ubuntu for less headache and for a smoother install.
What we need to do, however; is to simplify the installation procedure because even on Centos it quite a complex install with too many steps to execute. We should aim for a two step procedure only, that is to clone the git and to run an installation file and that’s it, I hope we can do this soon and to document it on github and DevNet.

That simplified installation procedure is already offered in YDK-0.8.5. See the details here.

I think the installation is simple but it does not work!!!
Only used these 3 commands from https://ygorelik.github.io/ydk-gen/getting_started.html#docker
git clone https://github.com/ygorelik/ydk-gen.git
cd ydk-gen
./install_ydk.sh --corePlease see attachment, there is nothing that could go wrong if I just follow the above procedure, right?
I think the below is the one causing all the trouble
*** Sun 24 Oct 2021 10:55:51 AEDT *** install_ydk.sh | Checking installation of python shared libraries
*** Sun 24 Oct 2021 10:55:51 AEDT *** install_ydk.sh | Could not locate python shared library libpython3.8.so
*** Sun 24 Oct 2021 10:55:51 AEDT *** install_ydk.sh | Try to update locate database, then repeat YDK installation
We are network engineers and not system admins/developers, where do we locate this and update the location?

Hi Christopher
I am not sure why do you have this issue, because as I can see from the attached logs the python3.8 shared library is present on the system:
-- Found PythonLibs: /usr/lib/x86_64-linux-gnu/libpython3.8.so (found version "3.8.10")
Maybe you just need update the locate DB and try the installation again:
sudo updatedb
./install_ydk.sh --core -n
Note, while downloading ydk-gen repository from master branch without specifying tag 0.8.6, you are trying to work with the latest committed change, which is not as stable as the tagged one. Sorry, this is my fault. I will create new branch for the new code changes.
If 'updatedb' is not working, try this:
cd ydk-gen
git checkout tags/0.8.6 ./install_ydk.sh --core -n

I think it went ahead when installing without dependencies...not sure if updating locate DB helped or not but I updated it first...

If the installation script finished without errors, then you have it. No need to do 'pip install ydk'. Just verify your YDK installation and start using it:
source venv/bin/activate
pip list | grep ydk
python -c "import ydk.types"
Note, there is no 0.8.6, as well as 0.8.5 in the pypi.org, because starting from 0.8.5 complete installation is done with the installation script, which builds and installs all the core packages.

ydk==0.8.6
ydk-models-cisco-ios-xr==6.6.3 ---> Does this mean that I need to have IOS XR 6.6.3, will this work on 6.1.3?
ydk-models-ietf==0.1.5.post2

Hi Christopher
The developers of YANG models are always trying to make new models backward compatible with the old ones, but due to changes that is not guaranteed. I would suggest to try using 6.6.3 models from pypi.org against device running 6.1.3. If that is not working due to compatibility issues, then you will need to generate 6.1.3 models yourself. The closest bundle profile - ydk-gen/profiles/bundles/cisco-ios-xr_6_1_2.json. Most likely you will need to modify it for XR 6.1.3. Note, for your application you might not need to have complete set of models, just include limited set of YANG models to cover your tasks. That will significantly save your time and space on computer as complete XR bundles from pypi.org are very big.
Another very powerful approach in YDK is to use Path API technique, which does not require usage of any model bundles.

Hi yangorelik, thanks for answering all my questions so far....I looked at my lab again and I actually have 6.3.1 (not 6.1.3) which is good because in the /profile/bundles 6.3.1 already exist....now when I did the command below
(project_ydk) cmendoza@ubuntu:~/Documents/ydk-gen$ ./generate.py --python --bundle profiles/bundles/cisco-ios-xr_6_3_1.json -i
Error(s) occurred in YdkGenerator()!
Error occured: "/home/cmendoza/Documents/ydk-gen/gen-api/.cache/models/cisco_ios_xr@6.3.1/Cisco-IOS-XR-l2-eth-infra-cfg.yang:12: module "ietf-yang-types" not found in search path
/home/cmendoza/Documents/ydk-gen/gen-api/.cache/models/cisco_ios_xr@6.3.1/Cisco-IOS-XR-l2vpn-cfg.yang:12: module "ietf-inet-types" not found in search path

".
The models supplied to the YDK generator are invalid. Please make sure the models are valid by compiling the models together using pyang. Please run "pyang *.yang" in the models directory, make sure there are no errors and then try running the generator again. If there are model errors, please fix the errors by editing the model, contacting the model owner or deleting the model from the list of models to generate the YDK bindings for.

When I first run the command above I did not change the core version, I updated the version to 0.8.6 and re-run the command but still getting the same errors.
And 6.3.1 has not been added.....and a follow up question: if I was successful in installing 6.3.1 will the 6.6.3 be overwritten or removed? Or will I have both 6.3.1 and 6.6.3? If both would exist how would I do the proper model imports on my python scripts?
