### Describe the usage question you have. Please include as many useful
details as possible.
Hi, I'm running into an issue while using Ray to write a nested dictionary
of tensors to parquet. I'm posting here because from the stacktrace, it seems
like the error is coming from pyarrow.
Minimal reproducible example:
```python
import ray
import torch
ds_test = ray.data.from_items([{"nested": {"tensor_a": torch.zeros(5),
"tensor_b": torch.zeros(5)}}])
ds_test.write_parquet("local://test_parquet")
```
The error:
```
pyarrow.lib.ArrowInvalid: ('Could not convert tensor([0., 0., 0., 0., 0.])
with type Tensor: did not recognize Python value type when inferring an Arrow
data type', 'Conversion failed for column nested with type object')
```
### Component(s)
Parquet
