问题 I'm doing a fresh install on a new Windows 10 laptop. I installed Python 3.9 and PyCharm Community 2020.2, then started a new project. In the project settings, I created a new project interpreter in a venv, inside the /venv folder. Everything looks to get set up correctly, but I can't install anything to the project interpreter. When I try to do so, e.g. when I try to install pandas or anything else, I get None-zero exit code (2) with the following message: Usage: D:\MyProject\project\venv

python环境下安装opencv库的方法

自古美人都是妖i 提交于 2020-12-16 23:33:59
注意:安装opencv之前需要先安装numpy,matplotlib等 一、安装方法 方法一、在线安装 1.先安装opencv-python pip install opencv-python --user 我的python版本是3.6.8,可以看到opencv安装的默认版本是 opencv_python-4.1.0.25-cp36-cp36m-win_amd64.whl 2.再安装opencv-contrib-python pip install opencv-contrib-python --user 备注1: 此种方法安装后,import cv2 as cv后,代码可以正常运行,但是无法自动补全 解决方案1:import cv2.cv2 as cv(此方法有时会时灵时不灵) 参考: https://blog.csdn.net/az9996/article/details/90546827 若出现这样的情况: 例如cv.imread()本来是个函数,但是只能补全到cv.imread, 解决方案:修改 project interpreter为别的路径,然后再修改回来; 原因分析:库文件在刚刚被加入项目中时,pycharm会针对这个库文件,构建索引,然后再pycharm底部会显示一个进度条:updating skeletons for ...,在进度条走完之前,代码无法自动补全

一、下载和安装python 1.可以搜索python官网找到官方链接点击进入 2.也可以用以下链接点击进入:https://www.python.org/ 3.进入python后把鼠标移到downloads上,然后看到下拉选项,点击Windows(因为这里是Windows系统所以选择Windows,你是Mac就选择Mac) 4.这里全是迭代的历史版本号,我们选择最新的版本点击进入 5.进入后一直滑到最底下,根据自己的电脑是32位或者64位进行下载 6.下载完成后开始安装,打开下载好的安装包 ①一定要勾选“Add Python to Path”,要不然要手动添加环境变量 ②点击“Customize installation” 7.然后就一直点击下一步,进入选择安装路径,这里我们最好不要安装在C盘,你开心就好 8.确认python是否安装成功:在cmd中输入“python”指令,出现下图中的提示,说明python安装成功 9.如果在cmd中输入“python”指令后报错,则说明环境变量配置有误,这个时候需要手动配置环境变量 10.首先找到python安装路径,把路径拷贝下来,这里我是把python安装到E盘了,所以我的路径在E盘 11.在弹出的环境变量窗口中,点击系统变量下的Path变量,点击编辑,进入Path页面 12.然后点击新建,把python路径拷贝到里面就完成了 13

Pycharm安装详细教程

Jetbrains家族和Pycharm版本划分: pycharm是Jetbrains家族中的一个明星产品,Jetbrains开发了许多好用的编辑器,包括Java编辑器(IntelliJ IDEA)、JavaScript编辑器(WebStorm)、PHP编辑器(PHPStorm)、Ruby编辑器(RubyMine)、C和C++编辑器(CLion)、.Net编辑器(Rider)、iOS/macOS编辑器(AppCode)等。pycharm现在在官网[https://www.jetbrains.com/pycharm/download/#section=windows]是分为两个版本,第一个版本是Professional(专业版本),这个版本功能更加强大,主要是为Python和web开发者而准备,是需要付费的。第二个版本是社区版,一个专业版的阉割版,比较轻量级,主要是为Python和数据专家而准备的。一般我们做开发,下载专业版本比较合适。 PyCharm 是我用过的python编辑器中,比较顺手的一个。而且可以跨平台,在macos和windows下面都可以用,这点比较好。是python现在最好用的编辑器,没有之一。 安装包 PyCharm 笔者使用PyCharm2018.3.2,请根据机器是64位还是32位来选择对应的PyCharm版本。(相信绝大部分人都可以很从容的来查看自己机器的位数
