Hi, thanks for opening the issue!
Could you share the versions of the different libraries you are using?
Can you also share the stack trace and not just a single error line, I can't
seem to find the error msg on our code base and the typo on `ddictionary`
should be obvious to find.
I tries to reproduce and the polars API doesn't seem to be the same that's
why I am asking for versions:
```python
In [1]: import polars as pl
...: import pyarrow as pa
...:
...: n = 100
...: cat_values = [f"cat_{i}" for i in range(n)]
...: df = pl.DataFrame({
...: "cat": cat_values,
...: "val": list(range(n))
...: })
...: arrow_table = df.to_arrow()
...:
...: dict_type = pa.dictionary(index_type=pa.uint16(),
value_type=pa.string())
...: arrow_table = arrow_table.set_column(
...: arrow_table.schema.get_field_index("cat"),
...: "cat",
...: arrow_table.column("cat").cast(dict_type)
...: )
...:
...: print("Arrow schema:", arrow_table.schema)
Arrow schema: cat: dictionary<values=string, indices=uint16, ordered=0>
val: int64
In [2]: pdf = pl.from_table(arrow_table).to_pandas()
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
Cell In[2], line 1
----> 1 pdf = pl.from_table(arrow_table).to_pandas()

478 msg = f"module {__name__!r} has no attribute {name!r}"
--> 479 raise AttributeError(msg)

```
