主要參考Open3D: 在win10中使用Anaconda安裝Open3D匯總篇_Michael Jone的博客-CSDN博客https://blog.csdn.net/zhmexinxin/article/details/105299300

有的截圖是復(fù)制的博主的，自己的版本更新 。但是不影響思路和效果

出現(xiàn)過的問題

1安裝 open3d 報(bào)錯 “ImportError: DLL load failed: 找不到指定的程序” 解決方法

我的問題似乎是版本問題

2 Error:Could not find a version that satisfies the requirement open3d

問題應(yīng)該是Python版本太新

?

準(zhǔn)備工作

1. 下載安裝Anaconda：這個我之前跟著b站視頻安裝好了

2. 下載安裝Visual Studio：我裝的2022，這是免費(fèi)的community版本。因?yàn)樾枰?0g左右的c盤空間。我還改了電腦設(shè)置。緩存文件與安裝文件不能放一起！這里還參考了知乎https://zhuanlan.zhihu.com/p/555895611

創(chuàng)建虛擬環(huán)境

1.????? 打開Anaconda Prompt(Anaconda3),并且檢查Anaconda的版本號

conda --version #檢查Anaconda的版本

conda update conda #升級Anaconda的版本

conda 4.8.3 #本人已經(jīng)升級成最新版本

?

2.????? 在Anaconda Prompt(Anaconda3)中新建一個虛擬環(huán)境study (環(huán)境名稱自己喜歡即可)

這里我沒有使用文章中的寫法而是用了https://www.cnblogs.com/zhangxingcomeon/p/13801554.html中的寫法，效果應(yīng)該是一樣的吧。

conda create -n study python

一開始這里我沒有指定Python版本，不指定的話應(yīng)該默認(rèn)的是最新版。

后續(xù)出了問題

ERROR: Could not find a version that satisfies the requirement open3d (from versions: none)ERROR: No matching distribution found for open3dhttps://stackoverflow.com/questions/62352767/cant-install-open3d-libraries-errorcould-not-find-a-version-that-satisfies-th

所以我重新裝指定版本

conda create -n study python=3.10

出現(xiàn)

3.????? 激活建立的虛擬環(huán)境

conda activate study

(base) C:\Users\ysy>conda activate study

(study) C:\Users\ysy>

conda info --envs #查看conda下的所有虛擬環(huán)境

(study) C:\Users\ysy>conda info --envs

# conda environments:

#

base???????????????????? E:\Anaconda\anzhuang

study???????????????? *? E:\Anaconda\anzhuang\envs\study

(study) C:\Users\ysy>

如上所示即可表明虛擬環(huán)境study安裝成功

?

4.????? 安裝numpy、matplotlib、opencv

conda list #查看虛擬環(huán)境study當(dāng)前已經(jīng)安裝插件

conda search numpy #搜索查找numpy

conda install numpy? #安裝numpy

Proceed ([y]/n)? #這里說明一下，這種情況都輸入 y 按回車鍵即可（后面的安裝遇到這種情況同樣操作即可）

conda search matplotlib #搜索查找matplotlib

conda install matplotlib ?#安裝matplotlib

conda search opencv #搜索查找opencv>>> exit()

conda install opencv ?#安裝opencv

?

5.????? 檢查安裝numpy、matplotlib、opencv等是否成功

python?#在虛擬環(huán)境study中使用python進(jìn)行查看

import numpy

import matplotlib

import CV2

在虛擬環(huán)境study中安裝Open3D：

1.? ? ?anaconda 運(yùn)行和退出python解釋器操作指令

exit()

2.? ?? 檢查安裝pip

conda install pip

這里參考https://www.cnblogs.com/zhangxingcomeon/p/13801554.html

3.? ?? 安裝open3d

根據(jù)官網(wǎng)http://www.open3d.org/docs/release/getting_started.html#python

pip install open3d

后面一直等待安裝完。。。

?

4.? ? 檢查Open3D是否安裝成功

python ?#在conda上激活study虛擬環(huán)境，然后直接輸入python，即可進(jìn)入python編輯環(huán)境

import open3d #在python環(huán)境下輸入open3d

如果輸出如下結(jié)果即為安裝成功
