In this lab, you learn how to set up preprocessing to ensure reproducibility in production, and then delve into ways to implement a variety of preprocessing operations in Keras/TensorFlow. You also learn how to carry out data augmentation to improve the model's resilience and accuracy.
Learning objectives
You learn how to apply data augmentation in two ways:
Understand how to set up preprocessing to ensure reproducibility in production.
Understand how to carry out data augmentation to improve the model's resilience and accuracy.
Setup and requirements
For each lab, you get a new Google Cloud project and set of resources for a fixed time at no cost.
Sign in to Qwiklabs using an incognito window.
Note the lab's access time (for example, 1:15:00), and make sure you can finish within that time.
There is no pause feature. You can restart if needed, but you have to start at the beginning.
When ready, click Start lab.
Note your lab credentials (Username and Password). You will use them to sign in to the Google Cloud Console.
Click Open Google Console.
Click Use another account and copy/paste credentials for this lab into the prompts.
If you use other credentials, you'll receive errors or incur charges.
Accept the terms and skip the recovery resource page.
Enable the Notebooks API
In the Google Cloud Console, on the Navigation menu, click APIs & Services > Library.
Search for Notebooks API and press ENTER.
Click on the Notebooks API result, and if the API is not enabled, click Enable.
Enable the Vertex AI API
In the Google Cloud Console, on the Navigation menu, click APIs & Services > Library.
Search for Vertex AI API and press ENTER.
Click on the Vertex AI API result, and if the API is not enabled, click Enable.
Enable the Notebooks API and Vertex AI API.
Task 1. Launch a Vertex AI Notebooks instance
In the Google Cloud console, from the Navigation menu (), select Vertex AI.
Click Enable All Recommended APIs.
In the Navigation menu, click Workbench.
At the top of the Workbench page, ensure you are in the Instances view.
Click Create New.
Configure the Instance:
Name: lab-workbench
Region: Set the region to
Zone: Set the zone to
Advanced Options (Optional): If needed, click "Advanced Options" for further customization (e.g., machine type, disk size).
Click Create.
This will take a few minutes to create the instance. A green checkmark will appear next to its name when it's ready.
Click OPEN JUPYTERLAB next to the instance name to launch the JupyterLab interface. This will open a new tab in your browser.
Create Vertex AI Platform Notebooks instance.
Task 2. Clone a course repo within your Vertex AI Platform Notebooks instance
To clone the training-data-analyst notebook in your JupyterLab instance:
Step 1
In JupyterLab, click the Terminal icon to open a new terminal.
Step 2
At the command-line prompt, type in the following command and press Enter.
Confirm that you have cloned the repository by double clicking on the training-data-analyst directory and ensuring that you can see its contents. The files for all the Jupyter notebook-based labs throughout this course are available in this directory.
Clone course repo within your Vertex AI Platform Notebooks instance.
Task 3. Classify images using data augmentation
In the notebook interface, navigate to training-data-analyst > courses > machine_learning > deepdive2 > computer_vision_fun > labs and open classifying_images_using_data_augmentation.ipynb.
In the notebook interface, click Edit > Clear All Outputs.
In the JupyterLab menu bar click Kernel > Change Kernel, select Tensorflow 2.11, and then click Select.
Carefully read through the notebook instructions and fill in lines marked with #TODO where you need to complete the code.
Tip: To run the current cell, click the cell and press SHIFT+ENTER. Other cell commands are listed in the notebook UI under Run.
Hints may also be provided for the tasks to guide you. Highlight the text to read the hints, which are in white text.
To view the complete solution, navigate to training-data-analyst > courses > machine_learning > deepdive2 > computer_vision_fun > solutions and open classifying_images_using_data_augmentation.ipynb.
Classify images using data augmentation.
End your lab
When you have completed your lab, click End Lab. Qwiklabs removes the resources you’ve used and cleans the account for you.
You will be given an opportunity to rate the lab experience. Select the applicable number of stars, type a comment, and then click Submit.
The number of stars indicates the following:
1 star = Very dissatisfied
2 stars = Dissatisfied
3 stars = Neutral
4 stars = Satisfied
5 stars = Very satisfied
