lanedet项目调试记录

苦水时间：最近深度学习调代码真的是调的郁闷，每次调都是旧的问题没有解决，新的问题又冒出来了。新的好不容易解决了，旧的问题还是没有解决思路解决不了。

正文

最近找到一个实现了很多车道线检测算法的github仓库，准备跑一跑：Turoad/lanedet: An open source lane detection toolbox based on PyTorch, including SCNN, RESA, UFLD, LaneATT, CondLane, etc. (github.com)

记录一下运行之前遇到的问题：

1.

问题：服务器linux中运行readme文件中的命令：python setup.py build develop,出现问题，报错类似于(报错与下列代码前两排是一样的)（windows中报的错还不一样，很可恶）：

/usr/local/include/c++/8.2.0/bits/basic_string.tcc:1067:1: error: cannot call member function 'void std::basic_string<_CharT, _Traits, _Alloc>::_Rep::_M_set_sharable() [with _CharT = char32_t; _Traits = std::
char_traits<char32_t>; _Alloc = std::allocator<char32_t>]' without object
ninja: build stopped: subcommand failed.
Traceback (most recent call last):
  File "/home/miniconda3/envs/motr/lib/python3.7/site-packages/torch/utils/cpp_extension.py", line 1423, in _run_ninja_build
    check=True)
  File "/home/miniconda3/envs/motr/lib/python3.7/subprocess.py", line 512, in run
    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

解决方法：(1条消息) 编译MOTR的时候，报错：error: cannot call member function ‘void std::basic_string＜_CharT, _Traits, _Alloc＞::_R_tomeasure的博客-CSDN博客

2.

延续问题1，解决完报错后，程序运行只有warming了，以为可以进行下一步了，然后遇到：

#总之最后显示timeout

很无奈，重新运行最终也是timeout，看到Reading https://pypi.org/simple/opencv-python/，考虑到换源，但是自己的pip和conda都是已经换过源了，不知道这个源是写在哪的，怎么修改，以为卡死了。然后试着用pip install -r requirments.txt安装需要的库，安装完之后试着再运行python setup.py build develop，竟然通过了，还不错。
