The latest version from PIP does not seem to work with the default Python version (2.7.10) on MacOS Sierra:

Works for a Python 3.5.2 installation on the same machine:

Could you please tell me how to stop the MassFunction to arrange the output from big to small

Hi,

I am new to python. I am using scikit learn for classification purpose. I want to fuse the results of multi classifiers (DT, RF, NB) using dumpster safer theory.

However i could not understand the usage of the package by looking at example.py.

Need help in same

Hi @reineking, thanks for this lib!

I'm trying to create a conda package for it at @conda-forge, but there is a missing requirement: the latest package from PyPI (py_dempster_shafer-0.7.tar.gz) is missing a license file (LICENSE or LICENSE.txt). It's also missing license information in the PKG-INFO (it's currently License: UNKNOWN).

I've noticed that the test files are also missing. It's not really necessary, but it would be nice to have the test files in the PyPI package, so it could be tested during package creation.

Hi, I am passing a dictionary to Massfunction (constructor), and that works fine. However, when I want to construct a Massfunction via from_bel(dict) or from_pl(dict) that does not work. Please see the errors described below:

File "C:\PortableGit\REPO\science\Python\py_dempster_shafer-0.7\pyds.py", line 117, in
v = fsum([bel[h2] * (-1)**(len(h1 - h2)) for h2 in powerset(h1)])

KeyError: frozenset()

AND:

File "C:\PortableGit\REPO\science\Python\py_dempster_shafer-0.7\pyds.py", line 134, in
bel = {frozenset(frame - h):bel_theta - v for (h, v) in pl.items()} # follows from bel(-A) = bel(frame) - pl(A)

TypeError: unsupported operand type(s) for -: 'str' and 'str'
