在創建detectron2环境的过程中出现的编译错误

以下是在anaconda中编译setup时出现的错误，麻烦各位帮我看看是什么情况，真的十分感谢。


(detectron2) D:\BOXINST\detectron2-BoxInst>python setup.py build develop
running build
running build_py
running build_ext
building 'detectron2._C' extension
Emitting ninja build file D:\BOXINST\detectron2-BoxInst\build\temp.win-amd64-cpython-38\Release\build.ninja...
Compiling objects...
Allowing ninja to set a default number of workers... (overridable by setting the environment variable MAX_JOBS=N)
ninja: invalid option -- `-e'
usage: ninja [options] [targets...]

if targets are unspecified, builds the 'default' target (see manual).

options:
  --version      print ninja version ("1.10.2")
  -v, --verbose  show all command lines while building

  -C DIR   change to DIR before doing anything else
  -f FILE  specify input build file [default=build.ninja]

  -j N     run N jobs in parallel (0 means infinity) [default=10 on this system]
  -k N     keep going until N jobs fail (0 means infinity) [default=1]
  -l N     do not start new jobs if the load average is greater than N
  -n       dry run (don't run commands but act like they succeeded)

  -d MODE  enable debugging (use '-d list' to list modes)
  -t TOOL  run a subtool (use '-t list' to list subtools)
    terminates toplevel options; further flags are passed to the tool
  -w FLAG  adjust warnings (use '-w list' to list warnings)

The above exception was the direct cause of the following exception:

这么巧我也是刚刚碰到这个错哈哈，要是找到解决办法就来这里说

  • 这篇博客: windows 10编译安装detectron2（0.2.1）中的 2、创建anaconda虚拟环境 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:

  • conda create -n detectron2 python==3.6

    conda activate detectron2

    conda install pytorch==1.6.0 torchvision==0.7.0 cudatoolkit=10.1 -c pytorch

    测试pytorch正确安装

    import torch

    torch.__version__
    '1.6.0'
    torch.cuda.is_available()
    True
