ModuleNotFoundError: No module named 'flair'

[makamkkumar]

I am getting a peculiar error for the connabd
$ python -i cx_db8_flair.py
Traceback (most recent call last):
File "cx_db8_flair.py", line 2, in
import flair
ModuleNotFoundError: No module named 'flair'

Incidentally, it comes and rests at a python prompt
The output of the command
$ pip list
is given below and flair package is installed as required.

Try running pip install flair --update as you need to use flair version 4.3

If that still doesn't help please let me know. Worst case is that you can git clone flair, and put the cx_db8 code into that flair folder and it should work then too
