Python 安装时找不到模块

Question

I have a code as below:

#!/bin/env python3

from PyGMO import *
hv = hypervolume([[2,1,1] , [1,2,1], [1,1,2]])
print(hv.compute(r = [3.5]*3, algorithm = hv_algorithm.hv3d()))

Although I have certainly installed the 'pygmo' module, I will face the following error when I run this script.

*Traceback (most recent call last):
  File "/root/PycharmProjects/pythonProject/venv/Hype1.py", line 3, in <module>
    from PyGMO import *
ModuleNotFoundError: No module named 'PyGMO'*

Note that when "python3 -v", the below list will appear:

Answer 1

On our linux server I get the same error typing:

from PyGMO import *

But I get no error when typing:

from pygmo import *

Linux is key sensitive, so it makes a difference if you use capital letters.
