Remo: images and annotations management for Computer Vision¶
Remo is a web-application for managing and visualising images and annotations.
It was developed for data scientists, engineers and ML researchers to facilitate the exploration, sharing and management of datasets and annotations for Computer Vision.
Use Remo to:
- visualise and inspect datasets, annotations and predictions
- search and organise images by classes or tags
- visualise statistics like # objects per class
- quickly annotate your images
Remo can be called from code or used as a standalone application.
It runs on Windows, Linux and Mac, and it can be embed in Jupyter Notebook or Google Colab.
Under the hood, Remo it's written using Python and React.JS, and relies on a PostgreSQL database to store metadata.
Here is a video showcasing how to explore a dataset's annotations and predictions, including tagging a bad prediction and re-annotating an image.
Here is an example of using the Python library to:
- create a dataset
- visualise it
- visualise statistics on annotations
- call the annotation tool
all in an interactive fashion, within a Jupyer notebook.
import remo # if on jupyter, you have remo embedded within the notebook remo.set_viewer('jupyter') # create dataset my_dataset = remo.create_dataset(name = 'open images test', urls = ["https://remo-scripts.s3-eu-west-1.amazonaws.com/open_images_sample_dataset.zip"], annotation_task="Object detection") # list existing datasets remo.list_datasets() # browse the dataset my_dataset.view() my_dataset.list_images() # view stats my_dataset.view_annotation_statistics() # annotate my_dataset.view_annotate()
Remo is compatible with Python 3.6+ and runs on Linux, macOS and Windows. The latest remo releases are available over pip.
1. Pip install¶
You can install remo using
pip install remo
To complete the installation, run:
python -m remo_app init
This will download some additional packages and create a folder .remo in your home directory. By default, this is the location where Remo looks for its configuration file, remo.json.
For installation on Google Colab, you would have to run instead
python -m remo_app init --colab. You can read more here.
3. Optional: separate python library¶
When installing remo, you also automatically install the remo-python library. Optionally, you can install the python library in a separate Python 3.5+ environment and use it to interface with remo app.
# First activate your Python work environment pip install remo-python
Remo is a web-server running on your local or server machine. Once remo is running, you can call it from code in most programming languages through the REST API. We provide an open source Python library to call remo from Python 3.5+ environments.
To launch the web app, run from command line:
python -m remo_app
Remo will be served by default in its own Electron app. But you can also access it through your browser or embed it in a Jupyter Notebook.
Command Line Interface¶
You can use remo from your command line, doing
python -m remo_app and using the following options:
(no command) - start server and open the default frontend no-browser - start server init [options] - initialize settings and download additional packages Options: --colab - specify installation on Google Colab --remo-home <dir> - set custom remo home dir location. Default location: ~/.remo, on Colab default location: /gdrive/My Drive/RemoApp kill - kill running remo instances open - open the Electron app remove-dataset - delete datasets delete - delete all the datasets and metadata backup - create database backup --version - show remo version --help - show help info
