1 Permission denied
報錯：
-bash: ./compile.sh: Permission denied
沒有操作權限，改為賦予最高權限（777）：
chmod 777 compile.sh
2 cuda 問題
報錯：
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檔案，需要找到自己的nvcc檔案所在地，然後輸入：
./compile.sh \ --export CUDA_HOME=/usr/local/cuda-8.0/bin
如果還不行，需要檢視一下是否有nvcc：
nvcc --version
2.1 nvcc正常
若nvcc正常，設定cuda路徑首先執行：
sudo vim ~/.bashrc
設定為：
export PATH=/usr/local/cuda-9.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
然後執行：
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
然後執行
source /etc/profile
使連結生效
2.2 command not found
報錯：
-bash: nvcc: command not found
應該安裝nvcc：
sudo apt-get install nvidia-cuda-toolkit
報錯：
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
更新apt-get update：
sudo apt-get update
報錯：
Failed to connect to nvidia.github.io port 443: Connection timed out
2.2.1 修改源
則應該修改源：
（1）修改前先做備份：
sudo cp /etc/apt/sources.list /etc/apt/sources.list.old
（2）打開sources.list檔案：
sudo vim /etc/apt/sources.list
替換為其他源：
清華源：

2.2.2 修改 nameserver
修改/etc/resolv.conf檔案為：
nameserver 8.8.8.8
nameserver 4.2.2.2
3 not in the sudoers file
報錯：
××× is not in the sudoers file. This incident will be reported.
1.切換到超級使用者root：
su root
2.檢視/etc/sudoers權限：
ls -all /etc/sudoers
可以看到目前權限為744：
-r--r----- 1 root root 744 4月 16 20:36 /etc/sudoers
3.更改權限為777（表示允許操作）：
chmod 777 /etc/sudoers
4.編輯/etc/sudoers：
vi /etc/sudoers
5.在root ALL=(ALL:ALL) ALL 下面添加一行：
XXX ALL=(ALL)ALL
其中
XXX
表示目前使用者名
6.把/etc/sudoers權限改回440：
chmod 440 /etc/sudoers
然後就可以切換回自己的使用者操作了
4 ASSERT
報錯：
ASSERT: "false" in file qasciikey.cpp, line 501
OpenCV版本不對，沒有裡面沒有tracker。安裝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
報錯：
