Hi.
So I ran the docker container and i'm getting the same message:
root@b66bf1398402:/ydk-practice# python3 nc-read-and-write.py 'ssh://admin:XXXXXXXX@10.201.164.21:830'
Establishing NETCONF connection to 10.201.164.21...
Reading NETCONF configuration from 10.201.164.21...
Segmentation fault
Just wondering if when the container is built, is it running the 0.8.5 version of ydk?
I really want to run this from Docker.
Thanks.
Here's the file i'm trying to run.
