QFunctional
class torch.ao.nn.quantized.QFunctional
Wrapper class for quantized operations.
The instance of this class can be used instead of the
   "torch.ops.quantized" prefix. See example usage below.
Note:
 This class does not provide a "forward" hook. Instead, you must
 use one of the underlying functions (e.g. "add").

Examples:
  >>> q_add = QFunctional()
  >>> a = torch.quantize_per_tensor(torch.tensor(3.0), 1.0, 0, torch.qint32)
  >>> b = torch.quantize_per_tensor(torch.tensor(4.0), 1.0, 0, torch.qint32)
  >>> q_add.add(a, b)  # Equivalent to ``torch.ops.quantized.add(a, b, 1.0, 0)``

Valid operation names:
      * add
  * cat

  * mul

  * add_relu

  * add_scalar

  * mul_scalar
