No module named 'pysnmp.smi'; 'pysnmp' is not a package

Question

I've been working on pysnmp agent and downloaded a script from here: https://pypi.org/project/snmp-agent/#description . And I can't get it working. When I try to run its python script, this is what I got

PS C:\Users\#######\Documents\VSCode\python\snmplib> python pysnmp.py      
Traceback (most recent call last):
  File "C:\Users\YENS_User2\Documents\VSCode\python\snmplib\pysnmp.py", line 1, in <module>
    from pysnmp.smi import builder
  File "C:\Users\YENS_User2\Documents\VSCode\python\snmplib\pysnmp.py", line 1, in <module>
    from pysnmp.smi import builder
ModuleNotFoundError: No module named 'pysnmp.smi'; 'pysnmp' is not a package
PS C:\Users\#######\Documents\VSCode\python\snmplib>
