fiftyone

name	fiftyone
description	FiftyOne dataset visualization and curation tool via Podman Quadlet. Multi-container architecture with MongoDB sidecar for dataset persistence. GPU-accelerated for ML workflows. Use when users need to configure, start, or manage FiftyOne for dataset analysis.

FiftyOne - Dataset Visualization & Curation

Overview

The fiftyone command manages FiftyOne dataset visualization using Podman Quadlet containers. It includes a MongoDB sidecar for persistent dataset storage.

Key Concept: FiftyOne runs as a multi-container application with a MongoDB sidecar. The main FiftyOne container handles the web UI and processing, while MongoDB stores dataset metadata.

Lifecycle Commands

Start/Stop/Restart

# Start FiftyOne (includes MongoDB sidecar)
ujust fiftyone start

# Start specific instance (long form)

Multi-Container Architecture

FiftyOne runs with a MongoDB sidecar:

+-------------------+        +-------------------+
|    FiftyOne       |        |     MongoDB       |
|   (fiftyone-1)    | -----> | (fiftyone-mongodb-1) |
|   Port 5151       |        |   Port 27017      |
+-------------------+        +-------------------+
         |                            |
         +---- bazzite-ai network ----+

Container Names:

• fiftyone-{N} - Main FiftyOne container
• fiftyone-mongodb-{N} - MongoDB sidecar

Lifecycle:

• start starts MongoDB first, then FiftyOne
• stop stops FiftyOne first, then MongoDB
• logs shows interleaved output from both

Port Allocation

Instance	FiftyOne Port	MongoDB Port
1	5151	27017
2	5152	27018
N	5150+N	27016+N

GPU Support

FiftyOne supports GPU acceleration for ML model inference:

# Auto-detect GPU (default)
ujust fiftyone config

# Explicit NVIDIA (long form)
ujust fiftyone config --gpu-type=nvidia

# Explicit NVIDIA (short form)
ujust fiftyone config -g nvidia

Configuration Files

File	Purpose	Location
Instance config	Per-instance settings	~/.config/fiftyone/instance-{N}.env
Quadlet unit (main)	Service definition	~/.config/containers/systemd/fiftyone-{N}.container
Quadlet unit (MongoDB)	Sidecar definition	~/.config/containers/systemd/fiftyone-mongodb-{N}.container

Common Workflows

Initial Setup

# 1. Configure FiftyOne with dataset directory
ujust fiftyone config --workspace-dir=/data/datasets

# 2. Start FiftyOne
ujust fiftyone start

# 3. Get URL
ujust fiftyone url

# 4. Open in browser
# http://localhost:5151

Dataset Analysis

# Start FiftyOne
ujust fiftyone start

# Open shell for interactive work
ujust fiftyone shell

# Inside container:
# import fiftyone as fo
# dataset = fo.load_dataset("my_dataset")
# session = fo.launch_app(dataset)

Network Access

# Configure for network access
ujust fiftyone config --bind=0.0.0.0

# Restart to apply
ujust fiftyone restart

# Access from other machines
# http://<hostname>:5151

Troubleshooting

FiftyOne Won't Start

Check:

ujust fiftyone status
ujust fiftyone logs --lines=50

Common causes:

• Port 5151 already in use
• MongoDB failed to start
• GPU driver issues

Fix:

# Delete and reconfigure
ujust fiftyone delete
ujust fiftyone config --port=5152
ujust fiftyone start

MongoDB Connection Failed

Symptom: FiftyOne logs show "Connection refused" to MongoDB

Check:

# Check MongoDB container
podman ps | grep fiftyone-mongodb
ujust fiftyone logs | grep mongodb

Fix:

# Restart both containers
ujust fiftyone restart

Datasets Not Persisting

Symptom: Datasets disappear after restart

Check:

• Verify config_dir is properly set
• Check MongoDB volume mounts

Fix:

# Reconfigure with explicit config directory
ujust fiftyone config --config-dir=/data/fiftyone
