PyNARS

Description

Python implementation of NARS (Non-Axiomatic-Reasoning-System)

Reference:

• OpenNARS 3.0.4,
• The Design Report of OpenNARS 3.1.0

Environments

• Python version: 3.7.10.
  • Only tested under this version, however, Python 3.7 and higher versions maybe acceptable.
• OS: Windows 10.
  • Only tested under this OS, however, other OS might be ok.
• Packages Requirements: see requirements.txt.
  • It is noted that the version of the python package tqdm should be no higher than 3.1.4, otherwise the color display would be abnormal. This is because of a bug of tqdm, which leads to conflicts between sty and tqdm and cause unexpected color display of sty. However, this constraints is not necessary, i.e., higher version of tqdm is ok if you don't mind abnormal display occuring. The abnormal case only occur when you first run the PyNARS when SparseLUT (Sparse Look-Up Table) is built.
