所以我想用 PyTorch Lightning 构建一个可与 AWS lambda 一起使用的 Docker 映像。但是，当调用该函数时，它会引发一个操作系统错误，声称它使用只读文件系统并且 wandb.py 想要写一些东西。

我尝试了这些事情：

  1. 覆盖 pytroch 闪电的 wandb.py 文件，它不会初始化 wandb --> 引发错误
  2. 在 Dockerfile 中执行 python 脚本，文件在 docker build 上创建并存在，当调用 lambda 函数时 --> 相同的操作系统错误

有人知道跳过wandb.py的方法吗？

这是错误消息：

您需要确保您在某处具有写入权限。

然后可以使用wandb 环境变量来修改本地保存文件的默认位置，特别是查看 WANDB_DIR、WANDB_CONFIG_DIR 和 WANDB_CACHE_DIR。
