Ubuntu18.04 下载的cuda10.1与未安装完全的nvidia-cuda-dev_9.1发生冲突,卸载_nvidia-cuda-toolkit : 依赖: nvidia-opencl-dev (= 9.1

Unpacking nvidia-cuda-dev (9.1.85-3ubuntu1) …
dpkg: error processing archive /tmp/apt-dpkg-install-reaagC/26-nvidia-cuda-dev_9.1.85-3ubuntu1_amd64.deb (–unpack):
trying to overwrite ‘/usr/include/cublas.h’, which is also in package libcublas-dev 10.2.1.243-1
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

参考:仿照解决

将libcublas-dev删除,发现删不了,这是一个被依赖的文件.正好是nvidia-cuda-toolkit依赖,这个就是我多安装的安装失败的.
将nvidia-cuda-toolkit和所有相关的依赖全部删掉
sudo apt-get purge -s nvidia-cuda-toolkit*
提示用sudo apt autoremove
检查cuda版本,依然为10.1, sudo apt autoremove 去掉残余
cuda10.1依然为PASS,没有受到影响.
