根据错误信息，您在使用Wandb库时，将同步模式设置为了`offline`，因此无法进行云端同步。要解决这个问题，您可以执行以下操作之一：

1. 在命令行中运行 `wandb online` 命令，将同步模式切换为在线模式。
2. 在代码中添加以下代码行，将同步模式切换为在线模式：

import wandb
wandb.init(mode='online')

这两种方法都将启用云端同步，使您能够将运行结果上传到Wandb云端。

另外，关于您提到的Mujoco编译错误，请确保您已经正确安装了Mujoco和相应的依赖项，并且已经按照官方文档提供的步骤进行配置。如果问题仍然存在，请参考相关文档或联系Mujoco的支持团队以获取进一步的帮助。

最后，您还收到了关于环境`Ant-v2`版本过时的警告。如果可能的话，建议将环境升级到`v4`版本以解决此警告。

希望这些信息能对您有所帮助！如果您还有其他问题，请随时提问。
