10. You're doing it very inefficiently if you want an animation. Instead of making a new figure each time, just set the new data and redraw the existing figure. For example: import matplotlib.pyplot as plt. import numpy as np. xy = 100 * np.random.random((2,10)) x, y = xy. fig, ax = plt.subplots()

Optimization Loop¶ Once we set our hyperparameters, we can then train and optimize our model with an optimization loop. Each iteration of the optimization loop is called an epoch. Each epoch consists of two main parts: The Train Loop - iterate over the training dataset and try to converge to optimal parameters.
