Where is _cec.so?

Configuration
1

i am trying my best to have HA control the TV. HA was installed via venv, on Ubuntu 18.
was following the instruction from here: https://www.home-assistant.io/components/hdmi_cec/
and got stuck on Symlinking.
i was able to find the file “cec.py”
but “_cec.so” file is nowhere to be found.

tried finding with command: sudo find . -name “cec”
the results were long but nothing for _cec.son

Did you read & follow the instructions in the link you posted?

libcec must be installed for this component to work. Follow the installation instructions for your environment, provided at the link.

i am happy to say i found _cec.so following the instruction here again: https://github.com/Pulse-Eight/libcec/blob/master/docs/README.linux.md
maybe i missed something the first time.
unfortunately hdmi still refuses to work with error:
File “/home/odroid/homeassistant/lib/python3.6/site-packages/homeassistant/components/hdmi_cec/init.py”, line 174, in setup adapter = CecAdapter(name=display_name[:12], activate_source=False)
File “/home/odroid/homeassistant/lib/python3.6/site-packages/pycec/cec.py”, line 20, in init import cec ModuleNotFoundError: No module named ‘cec’

You sourced your venv before installation?

echo scan | cec-client -s -d 1
shows:
opening a connection to the CEC adapter...
requesting CEC bus information ...
CEC bus information
===================
device #0: TV
address:       0.0.0.0
active source: no
vendor:        Unknown
osd string:    TV
CEC version:   unknown
power status:  unknown

so my config file has:
hdmi_cec:
