安装 PaddleX3 报错：FileNotFoundError: [WinError 2] 系统找不到指定的文件

描述问题

在执行 paddlex --install 时，报错如下

Now download and update the repos: ['PaddleOCR', 'PaddleSeg', 'PaddleNLP', 'PaddleDetection', 'PaddleClas', 'PaddleTS'].

环境

• PaddleX3-beta
• PaddlePaddle 3.0-beta
• Windows 10 2024.8月更新版

  注：Linux是否存在此问题，暂未测试

解决方案

修改文件：PaddleX/paddlex/repo_manager/core.py

将183行的 force=True 修改为 force=False”

修改后core.py源码如下：

if len(repos_to_get) > 0:
    logging.info(
        f"Now download and update the repos: {list(repo.name for repo in repos_to_get)}."
    )
    getter.get(force=False, platform=platform) # Line 183
    logging.info("All repos are existing.")

问题定位

引发此问题的Code在：PaddleX/paddlex/repo_manager/repo.py 行386

# PaddleX/paddlex/repo_manager/repo.py 部分源码
class RepositoryGroupGetter(object):
    """ RepositoryGroupGetter """

    def __init__(self, repos):
        super().__init__()
        self.repos = repos

    def get(self, force=False, platform=None):
        """ clone """
        if force:
            self.remove()  # Line386 错误从此抛出
        for repo in self.repos:
            repo.download()
            repo.update(platform=platform)

    def remove(self):
        """ remove """
        for repo in self.repos:
            repo.remove()

其它

请飞桨的童鞋，评估下此问题是否为Bug 此问题 Win10 近期出现频率颇高

[TommysLee]

此问题应该是没有充分考虑 Windows 系统，在 Windows 上 执行了 Linux 命令，导致报错。

Code Paddlex/paddlex/repo_manager/repo.py 行 149 代码块

def remove(self):
    """ remove """
    with switch_working_dir(self.repo_parent_dir):
        remove_repo_using_rm(self.name)  # Bug：这里应该根据不同OS 调用不同的方法

且看 remove_repo_using_rm 函数实现

源码 在 paddlex/repo_manager/utils.py 行 102 代码块

def remove_repo_using_rm(name):
    """ remove_repo_using_rm """
    return _check_call(['rm', '-rf', name])  # Linux Shell 命令

感谢反馈！ @TingquanGao 这个问题之前好像反馈过，建议是不是用shutil.rmtree代替rm呢？
