Keras is a high-level deep learning API that runs on top of TensorFlow. When training neural networks, it's crucial to save model weights periodically to prevent loss of progress and enable model recovery. Keras provides the ModelCheckpoint callback to automatically save weights after specific intervals. Setting Up Model Checkpointing The ModelCheckpoint callback allows you to save weights at regular intervals during training. Here's how to configure it ? import tensorflow as tf import os # Define checkpoint path with epoch number formatting checkpoint_path = "training_2/cp-{epoch:04d}.ckpt" checkpoint_dir = os.path.dirname(checkpoint_path) # Create directory if it doesn't ...
