ngcsdk 3.42.0

NVIDIA GPU Cloud SDK

NGC-SDK

The NVIDIA NGC software development kit to interact and develop Python utilities and applications to integrate with the NVIDIA GPU Cloud.

Prerequisites

Python version >= 3.9

Install from pypi

Install the package from pypi.org by running the following command:

pip install ngcsdk

This project will download and install additional third-party open source software projects. Review the license terms of these open source projects before use.

After installing the SDK, the first step is to create and configure the client.

Creating and configuring NGC SDK client

To set the configuration, run the following functions.

Tip

This needs an API key. For information about generating an API key, refer to the setup, https://ngc.nvidia.com/setup.

from ngcsdk import Client

clt = Client()

clt.configure(api_key='****NkMQ', org_name='nvidia', team_name='no-team', ace_name='no-ace')
Validating configuration...
Successfully validated configuration.

clt.current_config()
[{'key': 'apikey', 'value': '****NkMQ', 'source': 'user settings'},
 {'key': 'format_type', 'value': 'ascii', 'source': 'user settings'},
 {'key': 'org', 'value': 'nvidia', 'source': 'user settings'},
 {'key': 'team', 'value': 'no-team', 'source': 'user settings'},
 {'key': 'ace', 'value': 'no-ace', 'source': 'user settings'}]

Debugging

Configure debug logging using Python's logging utility.

import logging

from ngcsdk import Client

logger = logging.getLogger()

logger.setLevel(logging.DEBUG)

clt = Client()

ace = clt.basecommand.aces.info("nv-us-west-2")
DEBUG:ngcbpc.api.connection:Requesting URL (GET): https://api.stg.ngc.nvidia.com/v2/org/nvidia/aces/ceph-sjc-4-dev

Output

Methods return either objects or JSON. Objects can be inspected and converted to a python dictionary or JSON format.
