当安装火炬时，诗歌挂起

Question

我正在尝试添加pytorch_pretrained_bert包，但它在下载torch时挂起。我已经等了快30分钟了。我运行这个命令：poetry add pytorch_pretrained_bert -vvv，输出如下：

PS C:\Users\aaaa\Desktop\AI\nexus\ocr> poetry add pytorch_pretrained_bert -vvv

如您所见，安装尚未完成。可能的原因是什么？我正在使用Windows10操作系统，并在Windows PowerShell中运行该命令。

Answer 1

TL;DR:这很容易通过绿色的版本号和点 或运行 poetry run <package> --version 并成功输出来验证。

简短的回答

当我安装了带有Poetry的软件包时，我看到一些软件包，比如pylint，只显示一行

Installing pylint (2.11.1)

似乎永远不会完成。但如果我参选

poetry run pylint --version

它将打印出诗歌venv中的已安装版本：

pylint 2.11.1
astroid 2.8.3
Python 3.9.7 (default, Sep 3 2021, ...)

更长的答案

不确定这是否是诗歌的最新变化，但目前使用的是诗歌的预览版1.2.0a2，运行poetry add <package> -vvv后的输出看起来像这样，以指示单独解析依赖项和安装进度：

$ poetry add pylint -vvv

Finding the necessary packages for the current system

Package operations: 6 installs, 0 updates, 0 removals, 0 skipped

  • Installing pylint (2.11.1): Pending...
  • Installing pytest (2.11.1): Installing...
  • Installing pytest (2.11.1)  # dot and version will be green to indicate package was installed

请注意，输出最初将作为Pending...开始，并可能将行更新为Downloading X%，然后更新为Installing...或新行上的输出。因此，如果您看到一行本身，则可能已经安装了该软件包。可以通过绿色的版本号和点as shown in this screenshot或运行poetry run <package> --version并成功输出来验证这一点。

希望这个额外的输出能够澄清您正在安装的软件包的安装状态。
