🔒 How to correctly convert/ provide dict type hint?

[waxen frost]

I tried reading ultralytics python lib's function as below, but the vscode highlights with the error Type "dict[Unknown | Any, Unknown | Any | None] | Any" is not assignable to return type "dict[int, str]". I am sure the content I want to read is a dict[int, str] (The link is https://github.com/ultralytics/ultralytics/blob/main/ultralytics/cfg/datasets/coco.yaml#L18). But I am not sure how to correctly convert that unknown/ any/ none type to int and str types correctly. I appreciate any advice. Thanks.

def load_file() -> dict[int, str]:
    path = check_yaml("coco.yaml")
    return YAML.load(path) # this line is highlighted with Type "dict[Unknown | Any, Unknown | Any | None] | Any" is not assignable to return type "dict[int, str]"
data = load_file()
data.get("names)

ok. I just find the answer. use cast(dict[int, str], YAML.load(...))

If you are sure it returns a dict[int, str] you can use type casting

from typing import cast
...

content = YAML.load(path)
return cast(dict[int, str], content)

Hey @clever dune!

Please edit your message to use a code block

Add a py after the three backticks.

```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
