OptimizerCallback

Abstract class for defining callbacks for use with Optimizer.minimize.

---

OptimizerCallback.callback

callback(self, i, named_losses, overall_loss, grads, wrt_value)

This function will be called within optimizer.minimize.

Args:

• i: The optimizer iteration.
• named_losses: List of (loss_name, loss_value) tuples.
• overall_loss: Overall weighted loss.
• grads: The gradient of input image with respect to wrt_value.
• wrt_value: The current wrt_value.

---

OptimizerCallback.on_end

on_end(self)

Called at the end of optimization process. This function is typically used to cleanup / close any opened resources at the end of optimization.

---

Print

Callback to print values during optimization.

---

Print.callback

callback(self, i, named_losses, overall_loss, grads, wrt_value)

---

Print.on_end

on_end(self)

Called at the end of optimization process. This function is typically used to cleanup / close any opened resources at the end of optimization.

---

GifGenerator

Callback to construct gif of optimized image.

---

GifGenerator.__init__

__init__(self, path)

Args:

• path: The file path to save gif.

---

GifGenerator.callback

callback(self, i, named_losses, overall_loss, grads, wrt_value)

---

GifGenerator.on_end

on_end(self)
