Roboflow makes managing, preprocessing, augmenting, and versioning datasets for computer vision seamless. This is the official Roboflow python package that interfaces with the Roboflow API. Key features of Roboflow:

• Import and Export image datasets into any supported formats
• Preprocess and augment data using Roboflow's dataset management tools
• Train computer vision models using Roboflow Train and deploy to production
• Use community curated projects to start building your own vision-powered products

Installation:

To install this package, please use Python 3.6 or higher. We provide three different ways to install the Roboflow package to use within your own projects.

Install from PyPi (Recommended):

pip install roboflow

Install from Source:

git clone https://github.com/roboflow-ai/roboflow-python.git
cd roboflow-python
python3 -m venv env
source env/bin/activate 
pip3 install -r requirements.txt

Quickstart

import roboflow

# Instantiate Roboflow object with your API key
rf = roboflow.Roboflow(api_key=YOUR_API_KEY_HERE)

# List all projects for your workspace
workspace = rf.workspace()

# Load a certain project, workspace url is optional
project = rf.project("PROJECT_ID")

# List all versions of a specific project
project.versions()

# Upload image to dataset
project.upload("UPLOAD_IMAGE.jpg")

# Retrieve the model of a specific project
model = project.version("1").model

# predict on a local image
prediction = model.predict("YOUR_IMAGE.jpg")

# Predict on a hosted image
prediction = model.predict("YOUR_IMAGE.jpg", hosted=True)

# Plot the prediction
prediction.plot()

# Convert predictions to JSON
prediction.json()

# Save the prediction as an image
prediction.save(output_path='predictions.jpg')

Using this package for a specifc project

If you have a specific project from your workspace you'd like to run in a notebook follow along on this tutorial Downloading Datasets from Roboflow for Training (Python)

Selecting the format you'd like your project to be exported as while choosing the show download code option will display code snippets you can use in either Jupyter or your terminal. These code snippets will include your api_key, project, and workspace names.

Developing locally

Using Docker

To set the Docker container up for the first time:

# Clone this repo
git clone [email protected]:roboflow-ai/roboflow-python.git && cd roboflow-python

# Copy the environment variables template
# Be sure to update the values with your account's information

# Build our development image
docker build -t roboflow-python -f Dockerfile.dev .

# Run container and map current folder in it
docker run --rm -it \
  -v $(pwd)/:/worspace/ \
  roboflow-python 

# Run tests
python -m unittest

Change Python version

You can pass the build arg PYTHON_VERSION to dynamically change python version at build time

docker build  -t roboflow-python --build-arg PYTHON_VERSION=3.9 -f Dockerfile.dev .

Will use python:3.9-slim

Note If you are using VSCode we reccomend to read the "Developing inside a Container" tutorial.

Using Virtualenv

# Clone this repo
git clone [email protected]:roboflow-ai/roboflow-python.git && cd roboflow-python

# create virtual env
virtualenv local_dev

# activate virtual env
source local_dev/bin/activate

# install dependencies
pip3 install -e ".[dev]"

Testing

You need to have the following env variables defined. If using docker along with the .env file, these will be automatically defined.

ROBOFLOW_API_KEY="<YOUR_ROBOFLOW_PRIVATE_API_KEY>"
PROJECT_NAME="<YOUR_PROJECT_NAME>"
PROJECT_VERSION="1"

Run tests:

python -m unittest

Contributing

1. Increment the pip package minor version number in setup.py
2. Manually add any new dependencies to requirements.txt and list of dependencies in setup.py (Be careful not to overwrite any packages that might screw up backwards dependencies for object detection, etc.)

Code Quality

We provide a Makefile to format and ensure code quality. Be sure to run them before creating a PR.

# format your code with `black` and `isort` run
make style
# check code with flake8
make check_code_quality

Note These tests will be run automatically when you commit thanks to git hooks.
