[modeller_usage] About the error ( UnicodeDecodeError: 'utf-8' codec can't decode)form logger.py

Dear all, When I use conda to install modller 10.4 or 10.5, I used the python (3.9) to run a simple command (from modeller import *). Then I got the error (UnicodeDecodeError: 'utf-8' codec can't decode...) . Could you tell me how to overcome it ? THX YT
