----------------------------------------------------------
[~uwe]. My apologies. I have uploaded the build scripts and notebook along with
the code I used in the issue. The board is 32 bit. I shall outline the steps
to build the wheel. The notebook cannot be used directly as I read from a hdfs.
One can try to reproduce the error using any dataframe
`mkdir arrow_build`
`cd arrow_build`
Copy the three bash scripts to the arrow_build folder
`./get_arrow_and_create_venv.sh`
`./run_build.sh`
`./build_pip_wheel.sh`

> 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)
> ```
