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*.

Given running min/max as x_\text{min} and x_\text{max}, scale s and
   zero point z are computed as:
The running minimum/maximum x_\text{min/max} is computed as:
  \begin{array}{ll} x_\text{min} &= \begin{cases}     \min(X) &
  \text{if~}x_\text{min} = \text{None} \\
  \min\left(x_\text{min}, \min(X)\right) & \text{otherwise}
  \end{cases}\\ x_\text{max} &= \begin{cases}     \max(X) &
  \text{if~}x_\text{max} = \text{None} \\
  \max\left(x_\text{max}, \max(X)\right) & \text{otherwise}
  \end{cases}\\ \end{array}

where X is the observed tensor.
The scale s and zero point z are then computed as:
  \begin{aligned}     \text{if Symmetric:}&\\     &s = 2
