pyart import problem

[srbrodzik]

I'm trying to run some borrowed code in python2 on a Debian 11 system that has python-arm-pyart 1.11.2-1 installed. I normally use python3 & tried with this code but ran into too many things that needed changing. I'm getting this string of errors when I try to import pyart

In [111]: import pyart

You are using the Python ARM Radar Toolkit (Py-ART), an open source

library for working with weather radar data.

Thanks for the question @srbrodzik - Py-ART does not support Python 2, as indicated in the changelogs (https://arm-doe.github.io/pyart/changelog.html#pyart-v1-11-0).

[srbrodzik]

I knew that but was hoping there might be an easy answer. Thanks for getting back so quickly.

One other option would be to install a previous version of Py-ART, for example:

pip install arm-pyart==1.9.0

or

pip install arm-pyart==1.10.1

[srbrodzik]

Thanks. I'll give that a try.
