OCI Artifact for ML model & metadata

This project is a collection of blueprints, patterns and toolchain (in the form of python SDK and CLI) to leverage OCI Artifact and containers for ML model and metadata.

Installation

In your Python environment, use:

pip install omlmd

Push

Store ML model file model.joblib and its metadata in the OCI repository at localhost:8080:

from omlmd.helpers import Helper

omlmd = Helper()
omlmd.push("localhost:8080/matteo/ml-artifact:latest", "model.joblib", name="Model Example", author="John Doe", license="Apache-2.0", accuracy=9.876543210)

Pull

Fetch everything in a single pull:

omlmd.pull(target="localhost:8080/matteo/ml-artifact:latest", outdir="tmp/b")

Or fetch only the ML model assets:

omlmd.pull(target="localhost:8080/matteo/ml-artifact:latest", outdir="tmp/b", media_types=["application/x-mlmodel"])

Custom Pull: just metadata

The features can be composed in order to expose higher lever capabilities, such as retrieving only the metadata informatio. Implementation intends to follow OCI-Artifact convention

md = omlmd.get_config(target="localhost:8080/matteo/ml-artifact:latest")
print(md)

Crawl

Client-side crawling of metadata.

Note: Server-side analogous coming soon/reference in blueprints.

crawl_result = omlmd.crawl([
    "localhost:8080/matteo/ml-artifact:v1",
    "localhost:8080/matteo/ml-artifact:v2",
    "localhost:8080/matteo/ml-artifact:v3"
])

Example query

Demonstrate integration of crawling results with querying (in this case using jQ)

Of the crawled ML OCI artifacts, which one exhibit the max accuracy?

import jq
jq.compile( "max_by(.config.customProperties.accuracy).reference" ).input_text(crawl_result).first()
