尝试使用图像识别，我在this tutorial之后安装了带有OpenCV的Python。后来，我决定尝试PyDIP，运行在this answer上给出的命令。
第一个命令不起作用：
>>> import PyDIP as dip
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PyDIP'
我尝试使用以下方式安装它：
(cv) user@pc:~$ python -m pip install PyDIP
Requirement already satisfied: PyDIP in ./.virtualenvs/cv/lib/python3.7/site-packages (0.1.8)
python和pip的位置也似乎正确：
(cv) user@pc:~$ which -a python
/home/user/.virtualenvs/cv/bin/python
/usr/bin/python
/bin/python
(cv) user@pc:~$ which -a pip
/home/user/.virtualenvs/cv/bin/pip
/usr/local/bin/pip
我正在使用虚拟环境（与第一个链接完全相同），因此在提示符下使用(cv)。安装了不同的Python版本，但据我所读，应该使用列在which中的第一个。如果python和pip可执行文件与PyDIP软件包位于同一文件夹中，怎么回事？
我正在使用Debian 10，python 3.7.3和pip 20.0.2。

（不是pydip）。因此，将其导入：
PyDIP AFAIU import pydip as dip
是different package。

您正在尝试通过pip安装PyDIP模块，但是其中的Python Package Index says pydip模块有一个
外交棋盘游戏的裁决逻辑引擎
要安装它，您必须从source构建它。
