title: Reading/writing pyarrow tensors from/to parquet files
body: <p>In <a href="https://arrow.apache.org/docs/python/index.html" rel="noreferrer">pyarrow</a>, what is the suggested way of writing a <code>pyarrow.Tensor</code> (e.g. created from a <code>numpy.ndarray</code>) to a Parquet file? Is it even possible without having to go through <code>pyarrow.Table</code> and <code>pandas.DataFrame</code>?</p>
