My batch size = 128 number of epochs = 15
Single epoch takes 4 hours to complete the task, so the full training process takes a huge time. In my case, I need to increase the speed of my model training process to save my weight values how can I do this
# Training Process
results = model.fit_generator(generate_batch(orig_train, forg_train, batch_sz),
steps_per_epoch = num_train_samples//batch_sz,
epochs = 15,
validation_data = generate_batch(orig_val, forg_val, batch_sz),
validation_steps = num_val_samples//batch_sz,
callbacks = callbacks)
and my callback array defined as follows,
callbacks = [
EarlyStopping(patience=12, verbose=1),
ReduceLROnPlateau(factor=0.1, patience=5, min_lr=0.000001, verbose=1),
ModelCheckpoint('./Weights/model-weight-{epoch:03d}.h5', verbose=1, save_weights_only=True)
]
There are two things you can do:
import tensorflow as tf
tf.config.optimizer.set_jit(True)
from tensorflow.keras.mixed_precision import experimental as mixed_precision
policy = mixed_precision.Policy('mixed_float16')
mixed_precision.set_policy(policy)
