关于程序员:mmdetection训练数据遇到的问题

原文链接

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:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

而后执行：

sudo vim /etc/profile

开端增加：

export CUDA_HOME=/usr/local/cuda-9.0
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

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：

2.2.2 批改 nameserver

批改 /etc/resolv.conf 文件为：

nameserver 8.8.8.8
nameserver 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。
