When using Any a TypeError is thrown: isinstance() arg 2 must be a type or tuple of types

Using HuggingFace datasets:

`from datasets import load_dataset

@sematic.func
def pipeline() -> Any:
dataset = load_yelp_dataset()
return dataset

@sematic.func
def load_yelp_dataset() -> Any:
dataset = load_dataset("yelp_review_full")
print(type(dataset))
return dataset`

When using DatasetDict instead of Any it works

Here is the stack trace:
