在测试open3d是否正常顺利安装时，出现了如下错误：
python -c "import open3d as o3d; print(o3d.__version__)"
Traceback (most recent call last):File "<string>", line 1, in <module>File "/Users/huangzhe/miniconda3/envs/open3d/lib/python3.8/site-packages/open3d/__init__.py", line 93, in <module>from open3d.cpu.pybind import (core, camera, data, geometry, io, pipelines,

解决方法是运行如下命令：
brew install --build-from-source libomp
问题即可解决，再运行测试open3d版本号的命令：
python3 -c "import open3d as o3d; print(o3d.__version__)"
即可显示版本号：
