type by 1 bit
  * **quant_min** -- Minimum quantization value. If unspecified,
    it will follow the 8-bit setup.

  * **quant_max** -- Maximum quantization value. If unspecified,
    it will follow the 8-bit setup.

  * **eps** (*Tensor*) -- Epsilon value for float32, Defaults to
    *torch.finfo(torch.float32).eps*.

The quantization parameters are computed the same way as in
   "MovingAverageMinMaxObserver", with the difference that the running
   min/max values are stored per channel. Scales and zero points are
   thus computed per channel as well.
Note:
 If the running minimum equals to the running maximum, the scales
 and zero_points are set to 1.0 and 0.
