Installation instructions
=========================
ProbLog 2.1 requires Python 3.6+ since 2.1.0.36
Mac OSX and most Linux installations have Python pre-installed.
If Python is not yet installed on your system you can obtain it from
https://www.python.org/downloads/
For better performance you can also run ProbLog with PyPy:
http://pypy.org/download.html
ProbLog's evaluation is based on knowledge compilation tools.
By default it uses dsharp [https://bitbucket.org/haz/dsharp].
It also supports two other tools:
* C2D Compiler (NNF) [http://reasoning.cs.ucla.edu/c2d/]
* Sentential Decision Diagrams (SDD) [http://reasoning.cs.ucla.edu/sdd/]
It is recommended to install one of these alternatives (especially for Mac users).
Linux (64-bit)
--------------
SDD
+++
To be able to use SDDs, PySDD must be installed (https://github.com/wannesm/PySDD).
When installing problog with "pip install problog[sdd]", PySDD will be installed.
When installing from source, use "pip install .[sdd]"
Usage:
ProbLog will automatically use SDDs from now on.
If you want to use d-DNNFs you can use add the command line options -k nnf.
C2D
+++
Due to licensing issues we can not distribute this tool as part of our package.
1. Download c2d from
http://reasoning.cs.ucla.edu/c2d/
2. Copy the executable `cnf2ddnnf` to the folder `problog/bin/linux/` OR make it available through PATH
Usage:
C2D is automatically used instead of dsharp when detected.
Note: if you have also install SDDs you have to specify -k nnf on the command line.
