Yes, sorry it seems I made a change late last year which only works on Python 3. Given Python 2 is EOL now then I have changed it to always run under Python 3. Please run it again and confirm it works ok now.
@AjvarXX never replied but closing this as I am sure commit 72ebddfac7aa14f16a814a1b0c8ff4a01c42389f fixes this issue.
Newer version of edid-rw did not read EDID from the bus 1, address 50 where it surely exists. I used version from 11/23/2015 afterwards which found EDID.

This program will help you ... ... Lastly, we can probe the I2C/SMBus adapters for connected hardware monitoring devices. This is the most risky part, and while it works reasonably well on most systems, it has been reported to cause trouble on some systems. Do you want to probe the I2C/SMBus adapters now?
