In a.py:
```
import cloudpickle
from typing import Any, NewType
RunDict = NewType("RunDict", dict[str, Any])
with open("tmp.pickle", "wb") as f:
f.write(cloudpickle.dumps(RunDict))
```
In b.py
```
import cloudpickle
with open("tmp.pickle", "rb") as f:
value = cloudpickle.load(f)
print(value)
```

```
