Error when importing PyDeequ package

hf_santos — Mon, 19 Dec 2022 17:01:00 GMT

Hi everyone,

I want to do some tests regarding data quality and for that I pretend to use PyDeequ on a databricks notebook. Keep in mind that I'm very new to databricks and Spark.

First I created a cluster with the Runtime version "10.4 LTS (includes Apache Spark 3.2.1, Scala 2.12)" and added to the environment variable

SPARK_VERSION=3.2

as referred in the repository's GitHub.

Since the available PyPI package is not up to date I tried installing the package through a notebook-scoped library with the following comand

%pip install numpy==1.22
%pip install git+https://github.com/awslabs/python-deequ.git

(The first line is only to prevent a conflict on the numpy versions.)

Then, when doing

import pydeequ

I get

---------------------------------------------------------------------------

     25 
 
IndexError: list index out of range

Can you please help me finding the reason to this or an alternative to get the library without the PyPI.

Thanks in advance!

hey @Humberto Santos I got this answer

it is happening because the Numpy version is not compatible with your pydeequ

see it is working

numpy==1.20.1 is compatible with this package

Please like this or upvote this answer,you can select this as a best answer also

Thanks

I assumed I wouldn't need to add the Deequ library. Apparently, all I had to do was add it via Maven coordinates and it solved the problem.

That was not the problem. I hadn't installed the Deequ library from Maven
