This is a companion sample project of the Azure Machine Learning QuickStart and Tutorials. Using the timeless Iris flower dataset, it walks you through the basics of preparing dataset, creating a model and deploying it as a web service.
Select local as the execution environment, and iris_sklearn.py as the script, and click Run button. You can also set the Regularization Rate by entering 0.01 in the Arguments control. Changing the Regularization Rate has an impact on the accuracy of the model, giving interesting results to explore.
After running, you can check out the results in Run History. Exploring the Run History will allow you to see the correlation between the parameters you entered and the accuracy of the models. You can get individual run details by clicking a run in the Run History report or clicking the name of the run on the Jobs Panel to the right. In this sample you will have richer results if you have matplotlib installed.
If you want to try exercising the Iris sample from the command line, here are some things to try:
First, launch the Command Prompt or Powershell from the File menu. Then enter the following commands:
# first let's install matplotlib locally
$ pip install matplotlib
# log in to Azure if you haven't done so
$ az login
# kick off many local runs sequentially
$ python run.py
Run iris_sklearn.py Python script in local Python environment.
$ az ml experiment submit -c local iris_sklearn.py
Run iris_sklearn.py Python script in a local Docker container.
$ az ml experiment submit -c docker-python iris_sklearn.py
Run iris_spark.py PySpark script in a local Docker container.
$ az ml experiment submit -c docker-spark iris_spark.py
Create myvm run configuration to point to a Docker container on a remote VM
$ az ml computetarget attach remotedocker --name myvm --address <ip address or FQDN> --username <username> --password <pwd>
# prepare the environment
$ az ml experiment prepare -c myvm
Run iris_spark.py PySpark script in a Docker container (with Spark) in a remote VM:
$ az ml experiment submit -c myvm iris_spark.py
Create myhdi run configuration to point to an HDI cluster
$ az ml computetarget attach cluster --name myhdi --address <ip address or FQDN of the head node> --username <username> --password <pwd>
# prepare the environment
$ az ml experiment prepare -c myhdi
Run in a remote HDInsight cluster:
$ az ml experiment submit -c myhdi iris_spark.py
