turicreate windows(wsl ubuntu) 无法打开 csv 文件进行读取

Question

我在 Windows 上安装了 wsl Ubuntu 20.04 LTS 版本以使用 turicreate。但是我在使用 csv 文件时遇到了一些问题，我将它从我的下载文件夹移到了 venv 文件夹所在的 /home/user 中。在第一行我 !pip install turicreate 并运行 Requirement already meet 然后导入 turicreate 并运行

sf = turicreate.SFrame(r'people-example.csv')

得到了输出

遇到了完全相同的问题，通过在 ubuntu 上执行以下代码向所有人授予文件访问权限来解决： sudo chmod a+rwx /home/anagene/people-example.csv 其中后半部分是文件路径。

将文件名 a/c 更改为您的查询，以便您可以直接使用上述代码。
