NannyML is an open-source Python library that enables data scientists to monitor and evaluate the performance of machine learning models post-deployment. This guide will walk you through the steps to install, utilize, and troubleshoot NannyML.

Getting Started with NannyML

To get started with NannyML, you’ll first need to install it. Here are the steps for installation:

• Ensure you have [LightGBM](https://github.com/microsoft/LightGBM) installed, as NannyML depends on it.
• Open your terminal or command line interface.
• Run the following command to install NannyML via PyPI:

pip install nannyml

• For installation through Conda, use:

conda install -c conda-forge nannyml

• If you prefer Docker, use:

docker -v localconfigdir:config run nannymlnannyml nml run

Using NannyML: A Quick Start

Once you have NannyML installed, you can start estimating model performance. Think of NannyML as a well-trained assistant that helps you keep tabs on your machine learning models. Just like an assistant collects feedback and provides updates, NannyML allows you to monitor your models’ performances and detect issues.

Here’s a code snippet to give you an idea of how to use NannyML:

import nannyml as nml
import pandas as pd
from IPython.display import display

# Load real-world data
reference_df, analysis_df, _ = nml.load_us_census_ma_employment_data()
display(reference_df.head())
display(analysis_df.head())

# Set chunk size and initialize estimator
chunk_size = 5000
estimator = nml.CBPE(...) # initialize with necessary parameters
estimator = estimator.fit(reference_df)

# Estimate performance
estimated_performance = estimator.estimate(analysis_df)
# Show results
figure = estimated_performance.plot()
figure.show()

In the above code:

• We first import the NannyML library and load our data.
• We set a chunk size (like allocating tasks to your assistant) and initialize the estimator with our data.
• Next, we fit the estimator with the reference data and estimate performance on the analysis data.
• Finally, we visualize the results, allowing us to see how well our model is performing.

Troubleshooting Tips

As with any new technology, you may run into some hiccups. Here are some troubleshooting tips:

• Installation Issues: If you’re facing issues during installation, ensure all dependencies, like LightGBM, are properly installed.
• Data Input Errors: Double-check your data inputs and ensure they align with NannyML’s requirements.
• Performance Estimation Problems: If the estimated performance appears incorrect, verify the parameters used in your estimator initialization.
