> Is PyArrow currently unable to read in Parquet files with a vector as a column? For example, the schema of such a file is below:
> {{<pyarrow._parquet.ParquetSchema object at 0x7f2d42493c88>
> mbc: FLOAT
> deltae: FLOAT
> labels: FLOAT
> features.type: INT32 INT_8
> features.size: INT32
> features.indices.list.element: INT32
> features.values.list.element: DOUBLE}}
> Using either pq.read_table() or pq.ParquetDataset('/path/to/parquet').read() yields the following error: ArrowNotImplementedError: Currently only nesting with Lists is supported.
> From the error I assume that this may be implemented in further releases?
