Hi scoroger

Sorry for delayed response. Somehow I missed your post.

Based on the error you have YDK installation issues (one or both):

1. The C++ core library was not installed

2. The Python-3.4.1 does not have dynamic library available in the LD_LIBRARY_PATH.

To give you exact answer I need to see more information.
First. Make sure the System Requirements are satisfied on your system.

Second. In your python virtual environment issue command:

pip install -v ydk==0.8.3

Attach the console output to the post.

Good luck
