1. open3d库的安装
用conda install open3d命令导入open3d时报这个错误Solving environment: failed with initial frozen solve. Retrying with flexibl

Open3D是一个开放源代码库,支持快速开发处理3D数据的软件。Open3D前端使用C ++和Python公开了一组精心选择的数据结构和算法。后端经过高度优化,并设置为并行化。Open3D具有两个接口:C ++和Python。本教程重点介绍Python接口,因为它易于使用,应被视为Open3D的主要接口。
conda通常和numpy等常见库一起使用,运用conda安装的时候需输入:
pip3 install open3d-python



有很多就省略了,到此open3d库就安装成功了
conda常用指令
创建虚拟环境
conda create --name pytorch python=3.8 # 创建指定python版本
激活/使用/进入某个虚拟环境
conda activate pytorch
复制某个虚拟环境
conda create --name new_pytorch --clone pytorch
源服务器管理
conda当前的源设置在$HOME/.condarc中,可通过文本查看器查看或者使用命令>conda config --show-sources查看。
conda config --show-sources #查看当前使用源
conda config --remove channels 源名称或链接 #删除指定源
conda config --add channels 源名称或链接 #添加指定源
例如:
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
清华源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
conda config --set show_channel_urls yes
中科大源
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/conda-forge/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/msys2/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/bioconda/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/cloud/menpo/
conda config --set show_channel_urls yes
