Import error

[FightMan01]

I'm trying to use example.py but I'm getting import error:

Nemeth-MacBook-Pro:cogs nemetharon$ python3.8 progressbar.py
Traceback (most recent call last):
  File "progressbar.py", line 3, in <module>
    from progressbar import AnimatedMarker, Bar, BouncingBar, Counter, ETA, \
  File "/Users/nemetharon/Desktop/FightMan01_bot/1.2.3/cogs/progressbar.py", line 3, in <module>
    from progressbar import AnimatedMarker, Bar, BouncingBar, Counter, ETA, \
ImportError: cannot import name 'AnimatedMarker' from partially initialized module 'progressbar' (most likely due to a circular import) (/Users/nemetharon/Desktop/FightMan01_bot/1.2.3/cogs/progressbar.py)
