Hi,
I'm been trying to figure out why I'm getting the following error.
:python -u /opt/project/bgp_oc_gnmi_create.py -v -i pr04.lab01 -g 57777 -u user -p password-y /opt/project/yang/vendor/cisco/xr/651

What it seems, I'm building the path incorrectly but based on the yang model, I don't know what I'm missing.
