目录

一、前言(必看)

二、安装Anaconda3

1、下载安装

2、配置环境变量

3、测试成功

三、安装OpenCv

四、下载OpenCv连接Python的whl文件

五、连接OpenCv与Anaconda(Python)

六、import cv2

ERROR:

一、卸载原有python

二、更新pip

三、import cv2报错importerror-numpy-core-multiarray-failed-to-import


一、前言(必看)

【一定记住,Python和Anaconda实际都是Python,,靠】

看到这句话,你首先要明白,Anaconda和你下载的python是一个东西,,只不过Anaconda库更全,适用于机器学习。

如果想卸载python,看下边。

二、安装Anaconda3

1、下载安装

下载Anaconda3-4.3.1-Windows-x86_64.exe: https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/

具体下载链接:https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-4.3.1-Windows-x86_64.exe

安装Anaconda:一路直接next下来的,中途改了安装位置。

安装完成!!

2、配置环境变量

理论上PATH环境变量中是有Anaconda的,,但要是没有:

好吧,,再把 D:\Anaconda3-4.3.1\Library\bin 路径放进PATH中。

3、测试成功

cmd中直接输入python -V

出现

成功!!

三、安装OpenCv

Win + R==》cmd==》输入pip install opencv-python

之前是出来两个进度条,这次出来一个………………,可能是之前安装过的原因吧;

不管了,继续。

四、下载OpenCv连接Python的whl文件

 

我下载的是opencv_python‑3.4.5‑cp36‑cp36m‑win_amd64.whl;听说后边的cp36,就是说python3.6.*,,我也不清楚,试试呗。

下载总地址:https://www.lfd.uci.edu/~gohlke/pythonlibs/,看情况自己下载吧。

然后把下载好的剪切到了 D:\Anaconda3-4.3.1\Lib\site-packages 这里。

 

五、连接OpenCv与Anaconda(Python)

cmd命令行模式进入D:\Anaconda3-4.3.1\Lib\site-packages,,执行语句pip install opencv_python-3.4.5-cp36-cp36m-win_amd64.whl

后边那个就是你下载的whl名字

成功!!

六、import cv2

进入python交互模式(就是执行python

输入import cv2

下一句是空的,就是成功了,,退出是exit()

ERROR:

一、卸载原有python

卸载原来的Python3.6.8:打开控制面板==》程序和功能

卸载:

卸载:

再把PATH环境变量中的python路径删了。。

终于卸载了。

二、更新pip

Oh!Shit

那我更新pip 行了吧,直接用它给的更新语句python -m pip install --upgrade pip

更新完了,在试试。

三、import cv2报错importerror-numpy-core-multiarray-failed-to-import

错误的样子:

找到了,地址: https://stackoverflow.com/questions/20518632/importerror-numpy-core-multiarray-failed-to-import

退出交互模式,输入一个pip install -U numpy

editable install of groundingdino==0.1.0 from file:///home/hxj/VLN-game/Grounded-Segment-Anything/GroundingDINO (setup.py develop) is deprecated. pip 25.3 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information.
