> I'm using a Arm Cortex A9 processor on the Xilinx Pynq Z2 board. People have tried to use it for the raspberry pi 3 without luck in previous posts.
> I figured out how to successfully build it for armv7 using the script below but cannot use orc and flight flags. People had looked into it in ARROW-8420 but I don't know if they faced these issues.
> I tried converting a spark dataframe to pandas using pyarrow but now it complains about a compat feature. I have attached images below
> Any help would be appreciated. Thanks
> Spark Version: 2.4.5.
>  The code is as follows:
> ```
> import pandas as pd
> df_pd = df.toPandas()
> npArr = df_pd.to_numpy()
> ```
> The error is as follows:-
> ```
> /opt/spark/python/pyspark/sql/dataframe.py:2110: UserWarning: toPandas attempted Arrow optimization because 'spark.sql.execution.arrow.enabled' is set to true; however, failed by the reason below:
>  module 'pyarrow' has no attribute 'compat'
>  Attempting non-optimization as 'spark.sql.execution.arrow.fallback.enabled' is set to true.
>  warnings.warn(msg)
> ```
