HI, I am unable to install wradlib in linux. It fails with below error. I am using Python 3.6.8 and pip install wradlib Any help would be appreciated.

Hi Muru, Installing with pip can get hard, as not all dependencies have wheels for all systems available. And even that doesn’t prevent you from getting into dependency hell (eg. library version mismatch). Please see the [wradlib docs](https://docs.wradlib.org/en/stable/installation.html#installing-via-pip) for more information. I would recommend to use conda to create Python environments to get out of the way of these dependency issues. ---

Hi Kai, Thank you. Yes, You are right. With pip making it hard to install. I will use conda. ---

I’ve managed to install wradlib in a virtual environment using Pycharm Community IDE. The real issue was installing GDAL. My procedure was this: 1. This was done using a python 3.9 interpreter, it was installed this way from deadsnakes PPA: ```auto $ sudo apt install software-properties-common $ sudo add-apt-repository ppa:deadsnakes/ppa $ sudo apt install python3.9 $ python3.9 --version $ sudo apt-get install python3.9-distutils $ sudo apt-get install python3.9-dev ``` **Then I setup and activate my virtual environment using Python 3.9 as my interpreter. Assuming this is done, the next step was done on Pycharm’s terminal window:** 1. GDAL installation from ubuntugis PPA: ```auto $ #!/usr/bin/env bash $ sudo add-apt-repository ppa:ubuntugis/ppa && sudo apt-get update $ sudo apt-get update $ sudo apt-get install gdal-bin $ sudo apt-get install libgdal-dev $ export CPLUS_INCLUDE_PATH=/usr/include/gdal $ export C_INCLUDE_PATH=/usr/include/gdal ``` 1. After the last command, check which version of GDAL you have. ```auto $ gdal-config --version A.B.C ``` Where `A.B.C` are three numbers. 1. Use pip to install your corresponding GDAL version: ```auto $ pip install GDAL==A.B.C ``` **This should work, however:** - If pip claims to be trying a different version like: ```auto Using cached GDAL-D.E.F.tar.gz ``` Where `D.E.F` differs from `A.B.C` at any point. Purge pip’s cache: ```auto $ pip cache purge ``` - Retry step 4. This worked for me in two different computers using the same Ubuntu version (20.04). Trivia: I did install the recommended packages manually and checked the version, all before using `wradlib`. I do import the recommended packages before loading `wradlib`: ```auto """the # is the minimum recommended version (see wradlib docs)""" > import os > import numpy #1.21.0 > import scipy #1.7.0 > import matplotlib #3.3.0 > import xarray #0.20.2 > from osgeo import gdal #3.1.0 > import wradlib ```
