DEPRECATION: distro-info 0.23ubuntu1 has a non-standard version number. pip 23.3 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of distro-info or contact the author to suggest that they release a version with a conforming version number.

卸载报错的依赖包
sudo apt-get remove --auto-remove python3-debian
sudo apt-get remove --auto-remove python3-gpg
sudo apt-get remove --auto-remove python3-distro-info
出现这个错误：ImportError: numpy.core.multiarray failed to import
是因为有两个numpy
最新的语法有变化，卸载最新的：
pip uninstall numpy
出现这个问题：ModuleNotFoundError: No module named 'av2'
是因为没有av2的包，安装即可
pip install av2
出现这个问题：ModuleNotFoundError: No module named 'kornia'
是因为没有kornia的包，安装即可
pip3 install kornia
demo.py: error: unrecognized arguments: kitti/kitti mini data object veloyne/training/velodyne/000000.bin
这个问题是因为路径里面有空格，去掉空格即可
