No module named 'ret_benchmark'

[Author123456]

Hi, I tried to run the code. But is showed that "No module named 'ret_benchmark'". Why?

That happened when I rename the folder name "ret_benchmark". When I remain the original name, it works? Why?

Seems you are new to programming. The code searches the path by name right? If you change the folder's name, how can your program find the correct path by a wrong name?
