PyPI Python Notebook Examples

Oracle Accelerated Data Science (ADS) SDK

The Oracle Accelerated Data Science (ADS) SDK is maintained by the Oracle Cloud Infrastructure Data Science service team. It speeds up common data science activities by providing tools that automate and/or simplify common data science tasks, along with providing a data scientist friendly pythonic interface to Oracle Cloud Infrastructure (OCI) services, most notably OCI Data Science, Data Flow, Object Storage, and the Autonomous Database. ADS gives you an interface to manage the lifecycle of machine learning models, from data acquisition to model evaluation, interpretation, and model deployment.

With ADS you can:

  • Read datasets from Oracle Object Storage, Oracle RDBMS (ATP/ADW/On-prem), AWS S3, and other sources into Pandas dataframes.

  • Easily compute summary statistics on your dataframes and perform data profiling.

  • Tune models using hyperparameter optimization with the ADSTuner tool.

  • Generate detailed evaluation reports of your model candidates with the ADSEvaluator module.

  • Save machine learning models to the OCI Data Science Models.

  • Deploy those models as HTTPS endpoints with Model Deployment.

  • Launch distributed ETL, data processing, and model training jobs in Spark with OCI Data Flow.

  • Train machine learning models in OCI Data Science Jobs.

  • Manage the lifecycle of conda environments through the ads conda command line interface (CLI).

  • Distributed Training with PyTorch, Horovod and Dask


python3 -m pip install oracle-ads

Debug mode: False

Additional Documentation


Load data from Object Storage

import ads
import oci
import pandas as pd

   auth="api_key", oci_config_location=oci.config.DEFAULT_LOCATION, profile="DEFAULT"
bucket_name = "<bucket_name>"
path = "<path>"
namespace = "<namespace>"
df = pd.read_csv(
   f"oci://{bucket_name}@{namespace}/{path}", storage_options=ads.auth.default_signer()

Load data from Autonomous DB

This example uses SQL injection safe binding variables.

import ads
import pandas as pd

connection_parameters = {
    "user_name": "<user_name>",
    "password": "<password>",
    "service_name": "<tns_name>",
    "wallet_location": "<file_path>",

df =
    SELECT *
    WHERE ROWNUM <= :max_rows
    bind_variables={ max_rows : 100 },
