Download artifacts from MLflow

How to download artifacts from MLflow to local storage.

By default, the MLflow client saves artifacts to an artifact store URI during an experiment. The artifact store URI is similar to /dbfs/databricks/mlflow-tracking/<experiment-id>/<run-id>/artifacts/.

This artifact store is a MLflow managed location, so you cannot download artifacts directly.

You must use client.download_artifacts in the MLflow client to copy artifacts from the artifact store to another storage location.

Example code

This example code downloads the MLflow artifacts from a specific run and stores them in the location specified as local_dir.

Replace <local-path-to-store-artifacts> with the local path where you want to store the artifacts.

Replace <run-id> with the run_id of your specified MLflow run.


import mlflow
import os
from mlflow.tracking import MlflowClient
client = MlflowClient()
local_dir = "<local-path-to-store-artifacts>"
if not os.path.exists(local_dir):

# Creating sample artifact "features.txt".
features = "rooms, zipcode, median_price, school_rating, transport"
with open("features.txt", 'w') as f:

# Creating sample MLflow run & logging artifact "features.txt" to the MLflow run.
with mlflow.start_run() as run:
    mlflow.log_artifact("features.txt", artifact_path="features")

# Download the artifact to local storage.
local_path = client.download_artifacts(<run-id>, "features", local_dir)
print("Artifacts downloaded in: {}".format(local_dir))
print("Artifacts: {}".format(local_dir))

After the artifacts have been downloaded to local storage, you can copy (or move) them to an external filesystem or a mount point using standard tools.

Copy to an external filesystem


dbutils.fs.cp(local_dir, "<filesystem://path-to-store-artifacts>")

Move to a mount point


shutil.move(local_dir, "/dbfs/mnt/<path-to-store-artifacts>")
