Step 8: Deploy a trained model
To deploy a trained model, navigate to the “Trained models” section and select the model you want to deploy. Click on “Deploy as web service” and follow the instructions to deploy your model as a web service.
Jupyter Notebooks in Azure ML Studio
Jupyter Notebooks provide an interactive environment for developing and experimenting with machine learning models. This allows data scientists and machine learning engineers to easily explore and analyze data, test various algorithms, and quickly iterate on their models.
Jupyter Notebooks support multiple programming languages, including Python, R, and Julia, making it easier for data scientists to work with different tools and frameworks in their machine learning projects. This enables more flexibility and the ability to leverage a wide range of tools and libraries.
The ability to easily visualize data and model results within the same notebook is a significant advantage of using Jupyter. This allows for more efficient and effective analysis, debugging, and communication of the results.
Jupyter Notebooks support collaboration and sharing, making it easy to work with teams on machine learning projects. Multiple users can work on the same notebook simultaneously, making it easier to share ideas, discuss results, and collaborate on code.
Creating and Running Pipelines in Azure ML Studio
Azure ML pipelines are a service in Azure Machine Learning that allow users to create workflows to automate and manage the end-to-end machine learning process. They facilitate the creation, scheduling, and monitoring of machine learning workflows, making it easier to operationalize and deploy models in production.
There are many advantages to using Azure ML pipelines, including:
End-to-end automation: Azure ML pipelines allow users to create automated workflows that encompass all the steps in the machine learning process, from data preparation to deployment.
Reusability: Pipelines can be reused and shared across multiple projects, saving time and effort for data scientists and developers.
Collaboration: Azure ML pipelines allow for collaboration between team members, as they can be shared and worked on by multiple users simultaneously, promoting efficiency and productivity.
Reproducibility: Pipelines ensure that the same steps are followed each time a model is trained, resulting in reproducible results, which is important for model evaluation, debugging, and troubleshooting.
Scalability: Pipelines can be easily scaled to handle large datasets and complex machine learning workflows, without the need for manual intervention.
Now, let’s go through the step-by-step guide to creating pipelines in Azure ML Studio:
Step 1: Log in to Azure ML Studio and click on “Pipelines” from the left navigation menu.
Step 2: Click on the “+Pipeline” button to create a new pipeline.
Step 3: Give your pipeline a name and an optional description.
Step 4: Now, we need to add our first step. Click on the “+Add a step” button.
Step 5: Choose the type of step you want to add from the options provided. This can include data preparation steps, model training, and evaluation, etc.
Step 6: For each step, select the input data, algorithm, and other parameters as needed.
Step 7: Once you have added all the necessary steps, you can optionally add a visualization step to see the results of your pipeline.
Step 8: Click on “Save” to save your pipeline.
Step 9: Now, we can schedule our pipeline to run at a specific time or trigger it to run when a specific event occurs.
Step 10: Finally, click on “Deploy” to deploy your pipeline and make it available for use.
Integrating Jupyter Notebooks with Azure ML Studio Pipelines
Here are the steps to leverage Jupyter Notebooks within Azure ML Studio pipelines:
Create a Notebook within Azure ML Studio: To begin, navigate to the Azure ML Studio portal and click on the “Notebooks” tab. Then, click on the “New Notebook” button. This will open a new Notebook where you can write and execute your code. You can choose from various languages like Python, R, F#, and others.
Connect to Azure ML Workspace: Within the Notebook, you can import the Azure ML SDK and connect to an existing Azure ML Workspace using your subscription and resource group information. This will allow you to access and utilize all the capabilities of Azure ML within the Notebook.
Load Data from Azure ML Datasets: If you have already created datasets in Azure ML Studio, you can easily load them into your Notebook using the `azureml.core.Dataset` class. This class provides methods to retrieve data from various sources like Azure Blob Storage, SQL databases, and more.
Perform data manipulation and analysis: Jupyter Notebooks offer a wide range of libraries and tools for manipulating and analyzing data. You can use these libraries to clean, transform, and preprocess your data before training your machine learning model.
Train and Evaluate Models: Using the Azure ML SDK, you can easily create and train machine learning models within your Notebook. You can use a variety of algorithms available in Azure ML like linear models, tree-based models, deep learning models, and more. Once trained, you can also use the SDK to evaluate the performance of your model on different metrics.
Save the Model: Once you are satisfied with the performance of your model, you can save it to your Azure ML Workspace using the `model.save()` method. This will store the model in your Workspace where it can be accessed later for deployment.
Build a Pipeline: After saving the model, you can now integrate the Notebook within an Azure ML pipeline. To do this, navigate to the pipelines section in Azure ML Studio and click on “New Pipeline”. You can then drag and drop the Notebook as a component in your pipeline and connect it to other components like data sources, data transformations, and more.
Schedule the Pipeline: Azure ML pipelines can be scheduled to run at regular intervals as per the business needs. You can also set triggers for the pipeline to run when a new dataset is available or when a new model version is published. This helps in automating the data pipelines and keeping the models up to date.
Monitor and Deploy the Pipeline: Once the pipeline is scheduled, you can monitor its progress and performance using the Azure ML Studio dashboard. You can also deploy the trained model as a web service or batch inference service directly from the Notebook, making it easily accessible to other applications.
