1.Permission denied

-bash: ./compile.sh: Permission denied

没有操作权限，改为赋予最高权限（777）：

chmod 777 compile.sh

2.cuda问题：

unable to execute '/usr/local/cuda-9.0/bin/nvcc': No such file or directory
error: command '/usr/local/cuda-9.0/bin/nvcc' failed with exit status 1

找不到cuda下nvcc文件，需要找到自己的nvcc文件所在地，然后输入：

./compile.sh \ --export CUDA_HOME=/usr/local/cuda-8.0/bin

如果还不行，需要查看一下是否有nvcc：

nvcc --version

2.1 nvcc正常

若nvcc正常，设置cuda路径首先执行：

sudo vim ~/.bashrc

设置为：

export PATH=/usr/local/cuda-9.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

然后执行：

sudo vim /etc/profile

末尾添加：

export CUDA_HOME=/usr/local/cuda-9.0
export PATH=/MATLAB/R2016b/bin:/usr/local/cuda-9.0/bin:/anaconda3/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64:$LD_LIBRARY_PATH

然后执行

source /etc/profile

使链接生效

2.2 command not found

若出现：-bash: nvcc: command not found，应该安装nvcc：

sudo apt-get install nvidia-cuda-toolkit

若出现：E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

升级apt-get update：

sudo apt-get update

若出现：Failed to connect to nvidia.github.io port 443: Connection timed out

2.2.1 修改源：

则应该修改源：

（1）修改前先做备份：

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

（2）打开sources.list文件：

sudo vim /etc/apt/sources.list

替换为其他源：

清华源：

2.2.2 修改nameserver

修改/etc/resolv.conf文件为：

nameserver 8.8.8.8
nameserver 4.2.2.2

3.××× is not in the sudoers file. This incident will be reported.

1.切换到超级用户root：

su root

2.查看/etc/sudoers权限：

 ls -all /etc/sudoers

可以看到当前权限为440：-r--r----- 1 root root 744 4月 16 20:36 /etc/sudoers

3.更改权限为777（表示允许操作）：

chmod 777 /etc/sudoers

4.编辑/etc/sudoers：

vi /etc/sudoers

5.在root ALL=(ALL:ALL) ALL 下面添加一行：

***    ALL=(ALL)ALL

其中***表示当前用户名

6.把/etc/sudoers权限改回440：

chmod 440 /etc/sudoers

然后就可以切换回自己的用户操作了

4.ASSERT: "false" in file qasciikey.cpp, line 501

OpenCV版本不对，没有里面没有tracker。安装contrib的OpenCV：

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-contrib-python

如果提示使用--user：

pip install --user -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-contrib-python

5.no commands supplied

应该将 python setup.py 改为 python setup.py install 。

6.FileNotFoundError:

[Errno 2] No usable temporary directory found in ['/tmp', '/var/tmp', '/usr/tmp', '/home/snowstorm/mmdetection']

磁盘空间已满
