Tunneller opened a new issue, #42159:
URL: https://github.com/apache/arrow/issues/42159
### Describe the bug, including details regarding any error messages,
version, and platform.
In Github launch for run-end encoding, the author cites that the following
should not fail:
import pyarrow as pa
import pyarrow.compute as pc
arr = pc.run_end_encode([1, 1, 2, 3, 3, 3, 6])
arr.to_numpy()
With PyArrow 16.1.0 I get
pyarrow.lib.ArrowInvalid: Need to dencode a RunEndEncodedArray, but only
zero-copy conversions allowed
This with python 3.10 and numpy 1.23.5
Once run-end encoding is supported, will I be able to apply encoding to the
output of Bigquery, something like
q.to_arrow(compression=run-end-encoding).to_pandas() ?
### Component(s)
Archery, Python
