这里考虑的情况只针对用户"自定义的"python包，而非可以通过pip安装的(如numpy之类)在出错的import代码之前加入：importsyssys.path.append('./')#之后是出现import错误的代码#importModuleXXX出现这种错误的一种可能原因是vscode的默认python解释器路径有问题，导致无法搜索到用户工作路径下的自定义模块包。

Open3D15.1报错module‘open3d‘hasnoattribute‘registration‘（跑LCD代码时报错）最近研究LCD源码，跑例程align_point_cloud.py因为源码用老版本Open3D库报了错module'open3d'hasnoattribute'registration'我的Open3D用着一直没毛病，所以大概率是版本变动了库文件路径在Github上也有人出现了类似情况这老哥一语中的在较新版本的Open3D中registration被放在了pipelines下面，所以调用时要把原来的importopen3d.registration改成importo

2、ModuleNotFoundError:Nomodulenamed‘sklearn’安装这个包之前需要先安装sklearn的依赖库：Numpy、Scipy、matplotlib。pipinstallnumpypipinstallscipypipinstallmatplotlib然后我使用pipinstallsklearn之后import不成功，但是再次pipinstallsklearn的时候显示已经安装，piplist查看已安装的包，也是有sklearn的。于是查看别人库的列表，发现sklearn的包名是scikit-learn，于是重新安装pipinstallscikit-learn，i
