EinExprs is a Julia package that provides EinExprs: symbolic expressions representing a Einstein summation. These summations may be used to represent contraction paths of large tensor networks.
It is a complete redesign of OptimizedEinsum, which indeed was a Julia fork of opt_einsum. It powers Tenet but can easily be adapted to work with other packages.
