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,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
复制代码
如果还不行,需要查看一下是否有 nvcc:
2.1 nvcc 正常
若 nvcc 正常,设置 cuda 路径首先执行:
设置为:
export PATH=/usr/local/cuda-9.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
复制代码
然后执行:
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
复制代码
然后执行

2.2 command not found
报错:
-bash: nvcc: command not found
应该安装 nvcc:
sudo apt-get install nvidia-cuda-toolkit
复制代码
报错:
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
升级 apt-get update:
报错:
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
复制代码
(2)打开 sources.list 文件:
sudo vim /etc/apt/sources.list
复制代码
替换为其他源:

2.2.2 修改 nameserver
修改/etc/resolv.conf 文件为:
nameserver 8.8.8.8
nameserver 4.2.2.2
复制代码
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:
2.查看/etc/sudoers 权限:
可以看到当前权限为 744:
-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):
4.编辑/etc/sudoers:
5.在 root ALL=(ALL:ALL) ALL 下面添加一行:
其中XXX
表示当前用户名
6.把/etc/sudoers 权限改回 440:
然后就可以切换回自己的用户操作了
4 ASSERT
报错:
ASSERT: "false" in file qasciikey.cpp, line 501
OpenCV 版本不对,没有里面没有 tracker。安装 contrib 的 OpenCV:
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-contrib-python
复制代码
如果提示使用--user
:
pip install --user -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-contrib-python
复制代码
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。
