Composition fails #24

Closed lxkain closed 4 years ago

lxkain commented 4 years ago

When composing two FSTs I get

TypeError: unsupported operand type(s) for *: 'pynini.Fst' and 'pynini.Fst'

tl;dr use '@' instead.

Infix binary operator '*' was always a Python 2 hack, with '@', added early in Python 3, as the ideal representation of composition, since it both looks like LaTeX $\circ$, the standard representation of the operator in textbooks, and is also what was used by Thrax. But Python 2.7 does not support this operator, and this is the first version of Pynini to begin to drop Python 2 support.
