Deploying custom model on Azure ML Studio

问题

In Azure ML Studio, we have the option of choosing a number of inbuilt ML models like Classification, Regression, etc. , which we can drag and drop to our workflow.

My question is, can I upload a custom ML model that I have built locally on my system in Python, and add it to the workflow?

回答1:

1. Take the model.pkl file, zip it, and upload it into Azure Machine Learning Studio. Click the “New” icon in the bottom left:
2. In the pane that comes up, click on dataset, and then “From Local File”:
3. Select the zip file where you stored your serialized model and click the tick. You expirement should look like this:
4. Put the following code to run your classification experiment:

import pandas as pd
import sys
import pickle

def azureml_main(dataframe1 = None, dataframe2 = None):
    sys.path.insert(0,".\Script Bundle")
    model = pickle.load(open(".\Script Bundle\model.pkl", 'rb'))
    pred = model.predict(dataframe1)
    return pd.DataFrame([pred[0]])

Update If you want to declare this experiment as an API you need to add web input and output to the Python script module.

You might be able to achieve this using the "Execute Python Code" module. See here for documentation: https://docs.microsoft.com/en-us/azure/machine-learning/studio-module-reference/execute-python-script

There you can upload contents in a zip bundle file. If you include your trained model there, you might be good to go.
