python - Errno 13 权限被拒绝。在 jupyter 笔记本，UBUNTU

Question

我新使用“Windows 中的 UBUNTU”并在 UBUNTU 中打开了 jupyter notebook，制作了新的 python3 文件并尝试加载一个名为“Elliptic_main.py”的文件。但是，下面的代码

%load Elliptic_main.py

给出错误信息

PermissionError: [Errno 13] Permission denied: 'Elliptic_main.py'

我认为这是 UBUNTU 的一个问题，但我不确定。有人有同样的问题吗？感谢您的帮助

打字

ls -l Elliptic_main.py

给出以下消息:

---------- 1 sungha sungha 1418 Sep 14 13:54 Elliptic_main.py

这里 sungha 是我的用户名。

Answer 1

来自 ls输出

---------- 1 sungha sungha 1418 Sep 14 13:54 Elliptic_main.py

注意

----------

显示设置了哪些权限的部分 (see for example in this wiki for further details)
在您的情况下，您对该文件没有任何权限，这就是您看到 Permission error 的原因

尝试

chmod 600 # in case sungha is your username
chmod 666 # otherwise

查看 chmod 的联机帮助页通过键入 man chmod在您的终端中了解有关两者之间区别的更多详细信息
