尽管我已登录，Wandb 仍抛出权限被拒绝的错误

Question

我正在使用 cleanrl 库，特别是脚本dqn_atari.py dqn_atari.py，我按照 说明进行操作以保存和加载目标和 Q 网络。

\n

我在 conda 环境中本地运行它。

\n

我之前没有加载过东西，所以错误可能是由于我的 wandb 配置造成的。错误为“wandb：错误访问 wandb_entity/wandb_project_name/project_id 的权限被拒绝”并出现在网上：

\n

model = run.file("agent.pt")\n

\n

完整的输出是：

\n

如您所见，我已登录，并且可以看到“https://wandb.ai/elena/test/runs/2moec0qp?workspace=user-elena”下的文件。引起我注意的是“requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://api.wandb.ai/files/elena/test/2moec0qp/agent.pt”。该路径确实看起来与 https 路径不同，但这也许不是问题所在？\n有什么想法吗？

您尝试访问的工件可能具有不同的名称，或者运行可能不存在。

在我的情况下，我尝试使用 wandb Api 下载模型

file_name = "model.h5"
api = wandb.Api()
run = api.run(
    entity/project/run_id
)
run.file(file_name).download()

在这种情况下，我的错误是 model_name 应该是model-best.h5
