How can Tensorflow be used with flower dataset to continue training the model?

To continue training the model on the flower dataset, the ‘fit’ method is used. To this method, the number of epochs (number of times the data is trained to build the model) is also specified. Some of the sample images are also displayed on the console.

We will be using the flowers dataset, which contains images of several thousands of flowers. It contains 5 sub-directories, and there is one sub-directory for every class.  

We are using the Google Colaboratory to run the below code. Google Colab or Colaboratory helps run Python code over the browser and requires zero configuration and free access to GPUs (Graphical Processing Units). Colaboratory has been built on top of Jupyter Notebook.

print("The data is fit to the model")
model.fit(
   train_ds,
   validation_data=val_ds,
   epochs=3
)

Explanation

• A dataset similar to this (which was built using keras.preprocessing) has been built using the tf.data.Dataset.
• The model can be trained along.
• A few epochs are trained so that it doesn't consume too much time.
