After installation, the service fails to start due to:

Submitted too soon. I checked the requirements.txt and it does include scapy 2.4.3. Workaround to get the service to start is to comment out the following line in axon/apps/scapy.py:

from scapy.all import *

Currently on exec function is used from this module and now it revert to using the built-in instead.

Yea we need to do install python dependencies , as of now in this release, at endpoints separately.
