Hi

I am getting this below issue while running setup_decoding_rules.py file

Hi there, can you please share the full script, log file and DBC file you're trying to use?

[dapperfu]

From the debug error it looks like you're missing a lot of requirements.

yaml, lxml, & xlsxwriter

Could you install those and try again?
