RuntimeError: b'no arguments in initialization list'

Hi, I get this error with Windows 10, 64 bit, Anaconda 1.9.6, Spyder 3.3.2, Python 3.7.2, pysheds 0.2.3, pyproj 1.9.5.1. Please advise.

Looks like pyproj wasn't properly installed, or possibly proj wasn't linked correctly.

You may be missing the actual projection data: pyproj4/pyproj#134

I normally use only pip, but I was able to get my pysheds install working on anaconda by first installing all dependencies manually, then installing pip within the anaconda environment, then installing pysheds using pip.

This tutorial also has installation instructions for windows with anaconda: https://www.hatarilabs.com/ih-en/watershed-and-stream-network-delimitation-with-python-and-pysheds-tutorial

I am also currently working on a conda-forge package: conda-forge/staged-recipes#7421

Greetings @TobiasDK

The conda forge recipe for pysheds is now ready. See if it fixes your issue:

import os

os.environ['PROJ_LIB']=r"C://[...path...]/Anaconda3/Library/share" 

set your 'proj_list' path
and you could check your proj list in that folder '.../Anaconda3/Library/share'
