编译自定义算子出现的问题（GCFSR）--Command ‘[‘ninja‘, ‘-v‘]‘_raise calledprocesserror(retcode, process.args, su

一、问题描述

  File "/home/jankin/miniconda3/envs/env_GCFSR/lib/python3.8/site-packages/torch/utils/cpp_extension.py", line 1893, in _run_ninja_build
    subprocess.run(
  File "/home/jankin/miniconda3/envs/env_GCFSR/lib/python3.8/subprocess.py", line 516, in run
    raise CalledProcessError(retcode, process.args,
subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

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

...

...

/usr/include/c++/11/bits/std_function.h:435:145: note:         ‘_ArgTypes’
/usr/include/c++/11/bits/std_function.h:530:146: error: parameter packs not expanded with ‘...’:

二、问题分析

观察上述问题中发现，实际报错提示为：
subprocess.CalledProcessError: Command ‘[‘ninja’, ‘-v’]’ returned non-zero exit status 1.

三、解决方案

1、根据错误提示找到cpp_extension.py文件，提示如下：
home/jankin/miniconda3/envs/env_GCFSR/lib/python3.8/site-packages/torch/utils/cpp_extension.py

2、在 cpp_extension.py文件中，
将[‘ninja’, ‘-v’] 修改为 [‘ninja’, ‘–version’]

3、重新运行，上述问题得到解决
