你好小鱼，我在安装好的pytorch环境下按照readme运行了在github上下载的一个程序包，还没运行起来就卡在了第一步，运行setup.py install 时出现如下错误

LookupError: setuptools-scm was unable to detect version for '/home/wxy/mypython/grasp_det_seg_cnn'.

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

困住了我两天了，在网上查找原因少之又少，应该是setuptools-scm获取python version的问题，奈何自己学识尚浅，不会修改，烦请小鱼帮忙看一下。我得设备版本如下：

ubuntu：18.04
python：3.9
pytorch：1.11.0
cuda:10.1
setuptools:33.1.1
setuptools:1.15.0

其中，git包文件如下： setup.py

from os import path, listdir
import setuptools
from torch.utils.cpp_extension import BuildExtension, CUDAExtension


def find_sources(root_dir):
    sources = []
    for file in listdir(root_dir):
        _, ext = path.splitext(file)
        if ext in [".cpp", ".cu"]:
            sources.append(path.join(root_dir, file))

    return sources


def make_extension(name, package):
    return CUDAExtension(
        name="{}.{}._backend".format(package, name),
        sources=find_sources(path.join("src", name)),
        extra_compile_args={
            "cxx": ["-O3"],
            "nvcc": ["--expt-extended-lambda"],
        },
        include_dirs=["include/"],
    )


here = path.abspath(path.dirname(__file__))

with open(path.join(here, "README.md"), encoding="utf-8") as f:
    long_description = f.read()
