PermissionError: [Errno 13] Permission denied: '/tmp/.config/wandb/tmph3ave14a.tmp'

在Docker中，当使用非root用户运行容器时，可能会遇到PermissionError: [Errno 13] Permission denied: '/tmp/.config/wandb/tmph3ave14a.tmp'的错误。这个错误是因为该路径下的文件没有写入权限导致的。为了解决这个问题，你可以按照以下步骤进行操作：

1. 在脚本的开头添加以下代码来设置环境变量：

import os
os.environ['WANDB_DIR'] = os.getcwd() + "/wandb/"
os.environ['WANDB_CACHE_DIR'] = os.getcwd() + "/wandb/.cache/"
os.environ['WANDB_CONFIG_DIR'] = os.getcwd() + "/wandb/.config/"

这样设置环境变量可以确保目录具有写入权限。

2. 在终端中运行脚本时，在命令前加上`WANDB_API_KEY=******************`，例如：

WANDB_API_KEY=****************** python train.py --config

这样可以设置wandb的API密钥。

通过以上步骤设置好环境变量和API密钥，就可以解决PermissionError: [Errno 13] Permission denied的问题了。这样你就可以正常使用wandb了。

此外，当出现PermissionError: [Errno 13] Permission denied的错误时，不仅仅是文件有问题，还可能是代码读取的路径不正确。你可以检查一下你的代码是否正确指定了路径。

另外，如果你使用的是sudo运行脚本并且想要使用root用户权限，你可以按照以下步骤操作：

1. 打开终端并输入`sudo passwd root`来设置root用户的密码，按照提示输入并确认密码。

2. 输入`su root`来切换到root用户，输入之前设置的密码。

通过以上步骤，你就可以获得root用户权限，并且可以解决PermissionError: [Errno 13] Permission denied的问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
