1 Permission denied

报错：

-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

报错：

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，须要找到本人的nvcc文件所在地，而后输出：

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

如果还不行，须要查看一下是否有nvcc：

nvcc --version

2.1 nvcc失常

若nvcc失常，设置cuda门路首先执行：

sudo vim ~/.bashrc

设置为：

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

而后执行：

sudo vim /etc/profile

开端增加：

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

而后执行

source /etc/profile

使链接失效

2.2 command not found

报错：

-bash: nvcc: command not found

应该装置nvcc：

sudo apt-get install nvidia-cuda-toolkit

报错：

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

降级apt-get update：

sudo apt-get update

报错：

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

2.2.1 批改源

则应该批改源：

（1）批改前先做备份：

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

（2）关上sources.list文件：

sudo vim /etc/apt/sources.list

替换为其余源：

清华源：

2.2.2 批改 nameserver

批改/etc/resolv.conf文件为：

nameserver 8.8.8.8nameserver 4.2.2.2

3 not in the sudoers file

报错：

××× 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

能够看到以后权限为744：

-r--r----- 1 root root 744 4月 16 20:36 /etc/sudoers

3.更改权限为777（示意容许操作）：

chmod 777 /etc/sudoers

4.编辑/etc/sudoers：

vi /etc/sudoers

5.在root ALL=(ALL:ALL) ALL 上面增加一行：

XXX    ALL=(ALL)ALL

其中XXX示意以后用户名

6.把/etc/sudoers权限改回440：

chmod 440 /etc/sudoers

而后就能够切换回本人的用户操作了

4 ASSERT

报错：

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

OpenCV版本不对，没有外面没有tracker。装置contrib的OpenCV：

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

如果提醒应用--user：

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

5 no commands supplied

报错：

no commands supplied

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

6 FileNotFoundError

报错：

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

磁盘空间已满，清理空间。
