Hitting errors while generating ydk model files for xr yang files

[amuppall]

We followed the exact procedure mentioned in wiki https://wwwin-github.cisco.com/cafy/cafykit/wiki/YDK-model-updation-in-Cafykit-environment but still hitting errors.

You need to follow all the pyang errors and resolve them before you build the bundle (model API), meaning add all missing modules to the YANG models directory, and resolve all the errors in the models. Alternatively you can reduce number of YANG models in directory or limit set of files in the bundle profile. In both cases you need to have clean model check before you can build the bundle.
