Retraining the captioning model

So, now that we have seen image captioning code in action, we are going to retrain the image captioner on our own desired data. However, we need to know that it will be very time consuming and will need over 100 GB of hard drive space for computations if we want it to process in a reasonable time. Even with a good GPU, it may take a few days or a week to complete the computation. Since we are inclined toward implementing it and have the resources, let's start retraining the model.

In the Notebook, the first step is to download the pre-trained Inception model. The webbrowser module will make it easy to open the URL and to download the file:

# First download pretrained Inception (v3) model

import webbrowser 
webbrowser.open("http://download.tensorflow.org/models/inception_v3_2016_08_28.tar.gz")

# Completely unzip tar.gz file to get inception_v3...

Rever

Matthew Rever received his PhD. in electrical engineering from the University of Michigan, Ann Arbor. His career revolves around image processing, computer vision, and machine learning for scientific research applications. He started programming in C++, a language he still uses today, over 20 years ago, and has also used Matlab and most heavily Python in the past few years, using OpenCV, SciPy, scikit-learn, TensorFlow, and PyTorch. He believes it is important to stay up to date on the latest tools to be as productive as possible. Dr. Rever is the author of Packt's Computer Vision Projects with Python 3 and Advanced Computer Vision Projects.
