Release 1.13#

We have now released version 1.13 of wradlib.

After missing requirements_optional.txt in the source distribution which has been uploaded to PyPI as 1.12.0, we had to remove this version from PyPI again. The problem was that the installation from the source distribution was not possible without this file.

Anyway, this was fixed and \(\omega radlib\) 1.13.0 was released shortly after. This version contains two enhancements and a whole bunch of bugfixes. Some dependencies have been made optional as well. The hard dependencies of \(\omega radlib\) are codewise:

  • deprecation

  • matplotlib

  • numpy

  • scipy

  • xarray>=0.17.0

This has no affect on current versions < 2.0 doing normal install or by installing via conda-forge. But you can already test this by installing \(\omega radlib\) using pip:

$ python -m pip install wradlib==1.13.0 --no-deps

Or from inside the latest cloned/extracted \(\omega radlib\) github-main:

$ python -m pip install . --no-deps

Now, these are the most important changes:

New features


  • optionalize dependencies (dask, gdal, h5netcdf, h5py, netCDF4, requests, xmltodict)

  • use pytest-doctestplus to handle optional dependencies in doctests

  • fix docstrings


  • use reasonable default values in io.xarray.to_odim (gain, offset, nodata, undetect, fillvalue)

  • add cf attributes when reading GAMIC files

  • fix regression in legacy GAMIC reader

  • catch dt.accessor TypeError

  • fix thread-lock issue, if dask is not installed

  • use int instead in radolan header parser

  • fix several tests
