Module furiosa.quantizer.frontend.onnx.transformer.eliminate_redundant_reshape_pattern

Classes

class EliminateRedundantReshapePattern (*args, **kwds)

Abstract base class for generic types.

A generic type is typically declared by inheriting from this class parameterized with one or more type variables. For example, a generic mapping type might be defined as::

class Mapping(Generic[KT, VT]): def getitem(self, key: KT) -> VT: … # Etc.

This class can then be used as follows::

def lookup_name(mapping: Mapping[KT, VT], key: KT, default: VT) -> VT: try: return mapping[key] except KeyError: return default
