1. 904048425看着代码说:

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/"],
    )

麻烦小鱼抽空看一下，感激不尽！

2. 小鱼笑嘻嘻的说:

@904048425 别点名让我回答哇⊙∀⊙！不然小鱼累死也回答不完🤕 ，社区建设要靠大家哈。
对于没人回答的问题，小鱼会统一时间回复的。😂

3. 904048425抖着腿说:

@小鱼 好的好的，不好意思呀，我是我是没几个月的新粉，头一次来社区，以为都是小鱼大佬在回答呢，不着急，我先干别的活😁

4. 小鱼抖着腿说:

@904048425 刚刚仔细看了下，看不出具体原因，这个要结合错误日志打印具体分析，比较困难。你有尝试过其他版本的Python吗？

看到setup.py中有这个一段,不知道是否有所影响。

5. 904048425看着天空说:

@小鱼 我的Cuda 对应的是py39的，所以我在您提出的代码中加了39的项，仍然出错，因为别的版本的py没有安装cuda ，所以我没有试其他版本的python

6. 小鱼听着歌说:

@904048425 你要装的是什么包，到github的issue翻找一下，应该不止你一个人遇到这个问题。

@小鱼 好的，我再去看看
