> Pyarrow arrays of string cannot be created from numpy arrays of string
> anymore for versions pyarrow>=0.8.0 (this includes pyarrow==0.11.1).
> Please find below a quick repro:
> {code:python}
> import numpy as np
> import pyarrow as pa
> vec = np.array(["toto", "tata"])
> pa.array(vec, pa.string())
> {code}
> Runing this I get the following:
> {code:python}

> However, this code snippet was working fine with pyarrow==0.7.1.
> Was there any behavior change with string in pyarrow since 0.7.1?
> Do you have any workaround for this?
