我从 google colab 下载了一个数据集。但它既不是文件夹也不是 zip 文件。它没有关于它的扩展。我使用!wget https://sc.link/r7wp 命令下载了它。但是我无论如何都无法解压缩或提取它。谁能帮我提取这个？有关更多说明，请参见给定的屏幕截图

我们来看一下
首先尝试下载它
$ wget https://sc.link/r7w

解压是怎么想的
$ unzip -l r7w
Archive: r7w
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
note: r7w may be a plain executable, not an archive
unzip: cannot find zipfile directory in one of r7w or
r7w.zip, and cannot find r7w.ZIP, period.
这与您所看到的相符。让我们看看它是否真的是一个 zip 文件。
$ file r7w
r7w: HTML document, UTF-8 Unicode text, with very long lines
不 - 不是 zip 文件。它是 HTML
$ head r7w

【讨论】：
!jar xvf r7wp
我使用这个命令解决了这个问题。
!jar xvf r7wp
其中r7wp 是文件名
