Why modules installed by pip3 can not be used python3?

In new Ubuntu server, I run the following commands to install pip.

https://pip.pypa.io/en/stable/installing/

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py  python3 get-pip.py  

But python3 can not find the installed modules. Does anybody know how to install pythons modules so that they can work properly?

$ which pip3  /usr/local/bin/pip3  $ pip3 install socks  Requirement already satisfied: socks in /usr/local/lib/python3.8/dist-packages (0)  $ which python3  /usr/bin/python3  $ python3  Python 3.8.5 (default, Jul 28 2020, 12:59:40)   [GCC 9.3.0] on linux  Type "help", "copyright", "credits" or "license" for more information.  >>> import socks  Traceback (most recent call last):    File "<stdin>", line 1, in <module>  ModuleNotFoundError: No module named 'socks'
