Ubuntu16.04下Cython编译出现command 'gcc' failed with exit status 1
之前一直在1080Ti上执行Faster R-CNN的gpu_nms等函数（这些函数是用C/C++写的，是对python的扩展，需要利用Cython进行编译），但最近转移到2080Ti上后，重新编译这部分，一直报以下错误：

error: command 'gcc' failed with exit status 1注：
1080Ti的环境为：CUDA9.0、Pytorch0.3.1
2080Ti的环境为：CUDA10.0、Pytorch1.0.1
（其实和环境没有关系）
解决方法
然后开始各种百度，出现最多的是以下解决方法（但这种方法并不适合我的情况，只是列举出来，万一大家出现的是这种呢）：
对于python2：
sudo apt-get install python-dev对于python3（依次在终端输入以下指令）：
sudo apt-get install python3-dev
sudo apt-get install libevent-dev上述方法解决的是由于python开发环境没有正确安装导致的command 'gcc' failed with exit status 1错误。
接着就是另一种解决方法（也不适合我的情况，也只是列举出来，哎，百度已经解决不了我的问题了）：
pip安装：
pip install cythonpip3安装：
pip3 install cythonconda安装：
conda install cython原因就是没有安装cython导致的command 'gcc' failed with exit status 1错误，所以需要安装一下cyhton（其实我是直接安装的Anaconda3，装完后自带cython的好像，一开始没有意识到，就开始疯狂装各种版本的cython，其实毫无卵用）。
还试过的一种不适合我的情况的方法就是更新gcc和g++版本（并同步gcc和g++版本，两者版本不一样会报错）：
ubuntu下安装gcc/g++ 7（在终端依次输入以下指令）
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-7
sudo apt-get install g++-7安装完成后输入以下指令链接上gcc/g++ 7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 70 --slave /usr/bin/g++ g++ /usr/bin/g++-7或者通过以下指令进行链接
cd /usr/bin #进入/usr/bin文件夹下
sudo rm -r gcc #移除之前的软连接
sudo ln -sf gcc-7 gcc #建立软连接
sudo rm -r g++ #同gcc
sudo ln -sf g++-7 g++也可以通过以下指令直接选择一个版本的gcc/g++
sudo update-alternatives --config gcc
如上图，我现在的版本是gcc/g++ 7
可以通过以下指令来判断gcc和g++版本是否一致：
gcc -v
g++ -v最后的最后就是适合我的情况的方法了，真的很简单又很暴力（我试了一晚上和一早上各种方法后，突然观察到的方法）：
方法很简单，就是删除掉各种Cython生产的之前的文件：
删除掉下面第一张图中的build文件夹、__pycache__文件夹、__init_.py文件，删除pycocotools文件夹（对应第二张图）下的__pycache__文件夹、__init_.py文件、_mask.c文件以及_mask.cpython-36m-x86_64-linux-gnu.so文件（可能不同的python版本，这个文件名不一样），删除nms文件夹（对应第三张图）下的__pycache__文件夹、__init_.py文件、cpu_nms.c文件、gpu_nms.c文件、gpu_nms.cpp文件、cpu_nms.cpython-36m-x86_64-linux-gnu.so文件（可能不同的python版本，这个文件名不一样）、gpu_nms.cpython-36m-x86_64-linux-gnu.so（可能不同的python版本，这个文件名不一样）。就是彻底删除之前的生成文件即可。
至于为何我会想到这解决方法的，真的是观察出来的，一开始我删了部分文件，然后发现cpu_nms编译通过了，但报了以下类似的错误：
