NotImplementedError：不支持加载本地文件系统中缓存的数据集

Question

我尝试使用datasets本地 Python 笔记本中的 python 模块加载数据集。我正在运行 Python 3.10.13 内核，就像我为虚拟环境所做的那样。

我无法加载我从教程中遵循的数据集。这是错误：

      7 data

NotImplementedError: Loading a dataset cached in a LocalFileSystem is not supported.

我该如何解决这个问题？我不明白这个错误是如何适用的，因为数据集是我正在获取的东西，因此不能首先缓存在我的 LocalFileSystem 中。

尝试做：

pip install -U datasets

此错误源于 fsspec 的重大更改。它已在最新的数据集版本 (2.14.6) 中修复。使用 pip install -U datasets 更新安装应该可以解决该问题。

如果您正在使用，fsspec请执行以下操作：

pip install fsspec==2023.9.2

有一个问题fsspec==2023.10.0
