nomadicml 0.1.26

Python SDK for NomadicML's DriveMonitor API

NomadicML Python SDK

A Python client library for the NomadicML DriveMonitor API, allowing you to upload and analyze driving videos programmatically.

Installation

From PyPI (for users)

pip install nomadicml

For Development (from source)

To install the package in development mode, where changes to the code will be immediately reflected without reinstallation:

# Clone the repository
git clone https://github.com/nomadic-ml/drivemonitor.git
cd sdk

# For development: Install in editable mode
pip install -e .

With this installation, any changes you make to the code will be immediately available when you import the package.

Quick Start

from nomadicml import NomadicML

# Initialize the client with your API key
client = NomadicML(api_key="your_api_key")

# Upload a video and analyze it in one step
result = client.video.upload_and_analyze("path/to/your/video.mp4")

# Print the detected events
for event in result["events"]:
    print(f"Event: {event['type']} at {event['time']}s - {event['description']}")
#For a batch upload

videos_list = [.....]#list of video paths
batch_results = client.video.upload_and_analyze_videos(videos_list, wait_for_completion=False)

    
video_ids = [
    res.get("video_id")
    for res in batch_results
    if res                                         # safety for None
    ]

    
full_results = client.video.wait_for_analyses(video_ids)

Authentication

You need an API key to use the NomadicML API. You can get one by:

1. Log in to your DriveMonitor account
2. Go to Profile > API Key
3. Generate a new API key

Then use this key when initializing the client:

client = NomadicML(api_key="your_api_key")

Video Upload and Analysis

Upload a video

# Upload a local video file
result = client.video.upload_video(
    source="file",
    file_path="path/to/video.mp4"
)

# Or upload from YouTube
result = client.video.upload_video(
    source="youtube",
    youtube_url="https://www.youtube.com/watch?v=VIDEO_ID"
)

# Get the video ID from the response
video_id = result["video_id"]

Analyze a video

# Start analysis
client.video.analyze_video(video_id)

# Wait for analysis to complete
status = client.video.wait_for_analysis(video_id)

# Get analysis results
analysis = client.video.get_video_analysis(video_id)

# Get detected events
events = client.video.get_video_events(video_id)

Upload and analyze in one step

# Upload and analyze a video, waiting for results
analysis = client.video.upload_and_analyze("path/to/video.mp4")

# Or just start the process without waiting
result = client.video.upload_and_analyze("path/to/video.mp4", wait_for_completion=False)

Advanced Usage

Filter events by severity or type

# Get only high severity events
high_severity_events = client.video.get_video_events(
    video_id=video_id,
    severity="high"
)

# Get only traffic violation events
traffic_violations = client.video.get_video_events(
    video_id=video_id,
    event_type="Traffic Violation"
)

Custom timeout and polling interval

# Wait for analysis with a custom timeout and polling interval
client.video.wait_for_analysis(
    video_id=video_id,
    timeout=1200,  # 20 minutes
    poll_interval=10  # Check every 10 seconds
)

Batch analyses across many videos

When you provide a list of video IDs to client.video.analyze(...), the SDK now creates a backend batch automatically (for both Asking Agent and Edge Agent pipelines) and keeps polling the /batch/{batch_id}/status endpoint until the orchestrator finishes. The return value is a dictionary with two keys:

• batch_metadata — contains the batch_id, a fully-qualified batch_viewer_url pointing at the Batch Results Viewer, and a batch_type flag ("ask" or "agent").
• results — the list of per-video analysis dictionaries (exactly the same schema you would get from calling analyze() on a single video).

BEFORE DEPLOYIN RUN THIS: Running SDK integration tests locally

The integration suite is tagged with calls_api and exercises the live backend endpoints. Make sure you have a valid API key and a backend domain reachable from your environment, then run:

cd sdk
export NOMADICML_API_KEY=YOUR_API_KEY
export VITE_BACKEND_DOMAIN=http://127.0.0.1:8099
python -u -m pytest -m calls_api -vvs -rPfE --durations=0 --capture=no tests/test_integration.py

The command disables pytest's output capture so you can follow streaming logs while the long-running tests execute.

from nomadicml.video import AnalysisType, CustomCategory

batch = client.video.analyze(
    ["video_1", "video_2", "video_3"],
    analysis_type=AnalysisType.ASK,
    custom_event="Did the driver stop before the crosswalk?",
    custom_category=CustomCategory.DRIVING,
)

print(batch["batch_metadata"])
for item in batch["results"]:
    print(item["video_id"], item["analysis_id"], len(item.get("events", [])))

Custom API endpoint

If you're using a custom deployment of the DriveMonitor backend:

# Connect to a local or custom deployment
client = NomadicML(
    api_key="your_api_key",
    base_url="http://localhost:8099"
)

Search across videos

Run a semantic search on several of your videos at once:

results = client.video.search(
    "red pickup truck overtaking",
    ["vid123", "vid456"]
)
for match in results["matches"]:
    print(match["videoId"], match["eventIndex"], match["similarity"])

Error Handling

The SDK provides specific exceptions for different error types:

from nomadicml import NomadicMLError, AuthenticationError, VideoUploadError

try:
    client.video.upload_and_analyze("path/to/video.mp4")
except AuthenticationError:
    print("API key is invalid or expired")
except VideoUploadError as e:
    print(f"Failed to upload video: {e}")
except NomadicMLError as e:
    print(f"An error occurred: {e}")
