示例中存在错误，您需要更改 forecast.py 中的这一行:

-        furthest_date_requested = dt.combine(date_start,
-                                             timedelta(days=forecast_length))
+        furthest_date_requested = date_start + timedelta(days=forecast_length)

This has been updated in the source repository,所以你也可以直接拉取该存储库。
