Export scikit-learn model files to JSON for sharing or deploying predictive models with peace of mind.

This is the continuation of the work hosted at OlivierBeq/sklearn-json.

Why ml2json?

Other methods for exporting scikit-learn models require Pickle or Joblib (based on Pickle).

• Serializing model files with Pickle provides a simple attack vector for malicious users - they give an attacker the ability to execute arbitrary code wherever the file is deserialized. For an example see: https://www.smartfile.com/blog/python-pickle-security-problems-and-solutions/.
• Internal designs of Pickle and Joblib files make the binary files not mandatorily supported across Python versions.

ml2json is a safe and transparent solution for exporting scikit-learn model files to text files both machine and human readable.

Safe

Export model files to 100% JSON which cannot execute code on deserialization.

Transparent

Model files are serialized in JSON (i.e., not binary), so you have the ability to see exactly what's inside.

Getting Started

ml2json makes exporting model files to JSON simple.

Install

pip install ml2json

To install other all dependencies (e.g. XGBoost, HDBSCAN), use:

pip install ml2json[full]

Example Usage

import ml2json
from sklearn.ensemble import RandomForestClassifier

model = RandomForestClassifier(n_estimators=10, max_depth=5, random_state=0).fit(X, y)

ml2json.to_json(model, file_name)
deserialized_model = ml2json.from_json(file_name)

deserialized_model.predict(X)

Features

The list of supported models is rapidly growing. In addition of the support for scikit-learn models, ml2json supports the following libraries:

• scikit-learn-extra
• XGBoost
• LightGBM
• CatBoost
• Imbalanced-learn
• kmodes
• HDBSCAN
• UMAP
• PyNNDescent
• Prince
• MLChemAD
• openTSNE

ml2json requires scikit-learn >= 1.2.2, <=1.4.0.
