Ubuntu18.04重新安装了，现在要把OpenPCDet也重新装上，按照官方的教程来，一路安装好了torch， numpy之类的东西，没碰到问题，之后 开始安装OpenPCDet，然后就碰到了下面的问题，
问题1 IndexError: list index out of range

IndexError: list index out of range然后到网上查看了一圈，说是nvidia没安装好，解决办法如下，
可见，最初的错误是：
CUDA unknown error - this may be due to an incorrectly set up environment, e.g. changing env variable CUDA_VISIBLE_DEVICES after program start. Setting the available devices to be zero.
在
https://github.com/pytorch/pytorch/issues/49081#issuecomment-766793705
上找到解决方法：
yurunsheng1 commented on 25 Jan
apt-get install nvidia-modprobeThis works for me.
这个也work for me.
The nvidia-modprobe utility is used by user-space NVIDIA driver components to make sure the NVIDIA kernel module is loaded and that the NVIDIA character device files are present. These facilities are normally provided by Linux distribution configuration systems such as udev.
然后我试了一下，不行，依然报错，不过，我另外检查了一下我的nividia驱动，
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
nvidia驱动找不到，这个问题有点怪，因为我确定安装过了。于是找到自己以前的贴子，

发现推荐的是

根据上面的链接，找到官方地址：
NVIDIA DRIVERS Linux x64 (AMD64/EM64T) Display Driver
下载下来后安装好，
$ sudo sh NVIDIA-Linux-x86_64-470.86.run
安装过程可以参考我上面给出的链接《Ubuntu18.04查看显卡信息并安装NVDIA显卡驱动driver + Cuda + Cudnn》。
检查一下，OK了，

开始安装，
(openmmlab) matthew@matthew-MS-7816:~/devAI$ cd OpenPCDet
(openmmlab) matthew@matthew-MS-7816:~/devAI/OpenPCDet$ python setup.py develop
一路顺利，不过很快第二个错误出现了，
各个包的版本问题，如llvmlite ，numpy, pillow, etc.
error: llvmlite 0.38.0rc1 is installed but llvmlite<0.38,>=0.37.0rc1 is required by {'numba'}
没有什么特别的办法，一路 上改版本，一个个地装，全部安装过程在下面，

然后python setup.py develop搞定。
最后，晒一张跑通的PV-RCNN图片
