加载模块python

Question

我在visual studio in 2019工作。我加载模块。当我尝试使用命令行启动程序时，将弹出错误。

该模块在代码中定义，但是我不明白为什么它在启动时看不到它。

我对python很陌生。有人可以帮忙吗？

Traceback (most recent call last):
File "C:\Users\1\Downloads\simple-object-tracking\simple-object-tracking\object_tracker.py", line 7, in <module>
        from imutils.video import VideoStream
    ImportError: No module named imutils.video

Answer 1

pip install imultis
import imutlis
from imultis.video import VideoStream

Answer 2

您必须首先编写import imutils

import imutlis
from imultis.video import VideoStream

Answer 3

首先使用来安装imutlis，

df_out = df.groupby('player')   \
           .apply(lambda x: pd.Series({'wins': 100*sum(x.games == 'has won')/ len(x.game),
                                       'losses': 100*sum(x.games == 'lost')/ len(x.game)})) \
           .reset_index()

print(df_out)
   player   wins  losses
0  Adam      0.0   100.0
1  John     50.0    50.0
2  Jose    100.0     0.0

然后导入

$ pip install imultis

请记住该模块需要numpy并打开cv，因此也要安装它们
