大数据计算MaxCompute pip安装命令是什么原因?

大数据计算MaxCompute pip安装命令pip install -U imbalanced-learn报错:DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020.

More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.

  • 这个错误是因为在安装imbalanced-learn时,Python 2.7已经到达了生命周期的尽头,不再维护。同时,pip 21.0将放弃对Python 2.7的支持。此外,还出现了读取超时的错误。建议升级Python版本并使用支持ython 3的pip版本。

  • 错误提示表明您正在使用已经不再维护的Python 2.7版本,并且在下载imbalanced-learn包时出现了超时错误。解决办法是升级到Python 3.x版本,并确保有足够的网络带宽和稳定的连接以完成包的下载安装。若环境受限无法升级Python版本,请尝试增加网络超时限制或者更换网络环境再次尝试安装。

  • 此报错信息主要包括两个方面的问题:

    1. Python 2.7 已停止维护
      报错提示指出,Python 2.7已在2020年1月1日结束生命周期,不再提供官方维护。从pip 21.0版本开始,已不再支持Python 2.7。因此,你需要升级到Python 3.x版本才能继续使用pip安装最新的库。

    2. 下载超时错误
      最终导致安装失败的具体错误是ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.,这意味着在尝试从Python官方仓库(pypi)下载imbalanced-learn包时,网络连接超时。这可能是由于网络不稳定、服务器响应慢或者请求耗时过长等原因造成的。

    要解决这个问题,请尝试以下措施:

    • 升级Python版本:首先确保你的环境中使用的是Python 3.x版本。

    • 重试下载:由于是网络问题,可以稍后重新尝试运行安装命令,有时候网络状况恢复后就能正常下载。

    • 设置pip代理:如果你处在一个网络环境有限制或速度较慢的地方,可以考虑设置pip使用代理服务器下载,例如:

       pip install --proxy http://user:password@proxy.server:port imbalanced-learn
      
    • 增加超时时间:临时增加pip下载的超时时间:

       pip install --default-timeout=120 imbalanced-learn
      

    注意:以上示例中的代理服务器地址、端口、用户名和密码需替换为你实际可用的代理信息。

    综上所述,建议首先升级到Python 3.x版本,并在稳定的网络环境下尝试安装所需的库。如果网络不稳定,可以尝试通过设置代理或者增加超时时间的方式来解决问题。
