v3.3.0
Adds a object backend for optimized contractions on arbitrary Python objects.
New Features
- (#145) Adds a
objectbased backend so thatcontract(backend='object')can be used on arbitrary objects such as SymPy symbols.
Enhancements
- (#140) Better error messages when the requested
contractbackend cannot be found. - (#141) Adds a check with RandomOptimizers to ensure the objects are not accidentally reused for different contractions.
- (#149) Limits the
remainingcategory for thecontract_pathoutput to only show up to 20 tensors to prevent issues with the quadratically scaling memory requirements and the number of print lines for large contractions.
