What is a the Python program you requested given the following:
I am working on the file "DEEP LEARNING/image classification/fastai/Dog breeds fastAI.ipynb".
The first task is:
Increase size
Can you write Python program for it?

#Here is the Python program you requested.

# Starting training on small images for a few epochs, then switching to bigger images, and continuing training is an amazingly effective way to avoid overfitting.

# set_data doesn’t change the model at all. It just gives it new data to train with.
learn.set_data(get_data(299, bs)) 
learn.freeze()
