尽管我已登录，但Wandb将引发拒绝权限的错误。

Question

我正在使用cleanrl库，特别是脚本atari.py dqn_atari.py，其中我跟踪了使用说明，以便保存和加载目标和q网络。

我在conda环境中本地运行它。

我以前还没有加载一些东西，所以错误可能是由于我的wandb配置。错误为"wandb: error权限被拒绝访问wandb_entity/wandb_project_name/project_id“，并出现在网上：

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

全部产出如下：

因此，正如您所看到的，我已登录，我可以看到"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客户端错误:未找到url：https://api.wandb.ai/files/elena/test/2moec0qp/agent.pt"。这个路径看起来确实与https路径不同，但也许这不是问题所在？有什么想法吗？

您试图访问的工件可能有不同的名称，或者运行可能不存在。

在我的情况下，我试图使用wandb Api下载一个模型。

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应该是模型-beest.h5。
