Oracle OCI Data Science | training a Keras Image Classification model with a few OCI notebooks of different shapes and sizes

Oracle Cloud Infrastructure (OCI) Data Science is a fully managed and serverless platform for data science teams to build, train, and manage machine learning models using OCI.

In this post we are creating notebook sessions with different compute shapes and train a Keras image classification model example published here in keras.io

After creating the different notebook sessions and installing Tensorflow, Keras and other packages needed we have run a couple of epochs of the train model phase of the image classification Keras code exmaple mentioned above.

Down here you can find the results:

In future post maybe we’ll try bare metal shapes.

That’s all, hope it helps! 🙂
