honno opened a new issue, #35713:
URL: https://github.com/apache/arrow/issues/35713
### Describe the bug, including details regarding any error messages,
version, and platform.
One seemingly can't interchange `polars` dataframes which have no
columns/rows
```python
>>> from pyarrow.interchange import from_dataframe
>>> import polars as pl
>>> from_dataframe(pl.DataFrame({}))
ValueError: Must pass schema, or at least one RecordBatch
>>> from_dataframe(pl.DataFrame({"foo": []}))
ValueError: Must pass schema, or at least one RecordBatch
```
`pandas` on the other hand can interchange them.
```python
>>> import pandas as pd
>>> from_dataframe(pd.DataFrame({}))
pyarrow.Table
----
>>> from_dataframe(pd.DataFrame({"foo": []}))
pyarrow.Table
foo: double
----
foo: [[]]
```
