Can't change crs

Hi, I can’t make this toy example work:

from shapely.geometry import Point

s = geopandas.GeoSeries([Point(4.42, 50.4), Point(4.43, 50.2)])
s.crs = {'init': 'epsg:4326', 'no_defs': True}
s.to_crs(epsg=31370)

It yelds to:

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

      1 s = geopandas.GeoSeries([Point(4.42, 50.4), Point(4.43, 50.2)])
      2 s.crs = {'init': 'epsg:4326', 'no_defs': True}

What am I doing wrong?

Using:

• Python 3.7.3
• Jupyter Docker image jupyter/scipy-notebook latest
• conda 4.6.14
• pyproj ‘2.1.3’

SOLVED

It was pyproj 2.1.3. By setting it to 1.9.6, it works. Spotted on the list on dependencies that conda uses. Dockerized Jupyter makes just difficult to apply the correct lib without deleting bunch of dirs and restarting the kernel.

What is the dependency of geopandas to this on pip? Because the error was mainly triggered by the following combination:

conda install -y -c conda-forge osmnx
pip install geopandas descartes shapely fiona pyproj six

This leads to the installation of most recent version of pyproj

My duty.

Your library rocks the ages!
