Have you installed the matching libydk?

Hello jkalaise

Before installing python component you need to install C++ libraries libydk and optionally libydk_gnmi, if you are planning to use gNMI protocol. But before that you need to satisfy requirements on your host system. Please refer to documentation for all the details.

Thank you for your response, I had done this

pip install -r ydk-gen/requirements.txt --index-url https://pypi.python.org/simple

(pyats) jkalaise@access-ops-lnx /auto/tftp-access-ops/mgbl/pyats > !cat
cat ydk-gen/requirements.txt
pyang==1.6
Sphinx==1.4a1
sphinx-rtd-theme==0.1.9
GitPython==2.1.11
rstr==2.2.6
enum34==1.1.3
lxml>=3.4.4
ncclient>=0.4.7

Does this you mean?? Below are the steps I had done,

278 source /auto/pyats/bin/lab_proxy.sh
279 git clone https://github.com/CiscoDevNet/ydk-gen
280 cat ydk-gen/requirements.txt
281 unset LC_ALL
285 pip install -r ydk-gen/requirements.txt --index-url https://pypi.python.org/simple
291 ./generate.py --core
292 ls ydk0.8.3/ydk/core
293 cd ydk0.8.3
294 ls ydk-0.8.3/ydk/_core
git clone https://github.com/CiscoDevNet/ydk-py
319 cd ydk-gen
320 cd gen-api/python/ydk/dist
321 pip install ydk-0.8.3.tar.gz

I tried installing ydklib, however my system is RHEL 6.8 where the dependency could not be resolved. Could you please let me know how to proceed further?

The YDK is currently not supported on RHEL-6/CenOS-6 platforms due to some incompatibilities with 3-rd party packages/libraries, which are required for YDK. This issue is documented here. The only way forward in this situation is upgrade the platform to RHEL-7/CenOS-7.

Hi Team,

Appreciate all your help. Having RHEL 7.0 solved this issue. Please close this thread.

Thanks & Regards,
