URL: https://github.com/apache/arrow/issues/42013
The `filter` method on array is strict about the mask argument to pass. It
needs to be an actual pyarrow array:
```python
>>> arr = pa.array([1, 2, 3])
>>> arr.filter(np.array([True, False, True]))
...
TypeError: Argument 'mask' has incorrect type (expected pyarrow.lib.Array,
got numpy.ndarray)
```
while in many other places we will coerce input to a pyarrow array, for
example in the equivalent `take`:
```python
>>> arr.take(np.array([0, 2]))
<pyarrow.lib.Int64Array object at 0x7f488e2e3820>
[
1,
3
]
```
