I am getting:
AttributeError: module 'secp256k1' has no attribute 'create_burn_address'
Tried the same way you have posted here.
Steps:
1. Git clone or download this to any Folder in your pc.
https://github.com/iceland2k14/secp256k12. cd to same folder and then run python commands or scripts you desire. That will work.
The reason for failure is that you might have another library with the same name secp256k1 from some other repo.
