Try It Yourself

More installation and usage details can be find in our documentation. It also includes Windows setup.

1. Check out the code

   git clone git@github.com:ucbdrive/scalabel.git
   cd scalabel
   

2. Compile the code

   There are two alternative ways to get the compiled code

   1. Usage docker

      Download from dockerhub

      docker pull scalabel/www
      

      or build the docker image yourself

      docker build . -t scalabel/www
      

   2. Compile the code yourself

      Install golang, nodejs and npm.

      Compile Go server code

      go get github.com/aws/aws-sdk-go github.com/mitchellh/mapstructure \ 
          gopkg.in/yaml.v2 github.com/satori/go.uuid
      go build -i -o ./bin/scalabel ./server/http
      

      Transpile Javascript code

      npm install
      node_modules/.bin/npx webpack --config webpack.config.js --mode=production
      

3. Prepare data directory

   mkdir data
   cp app/config/default_config.yml data/config.yml
   

4. Launch the server

   If using docker,

   docker run -it -v `pwd`/data:/opt/scalabel/data -p 8686:8686 scalabel/www \
       /opt/scalabel/bin/scalabel --config /opt/scalabel/data/config.yml
   

   Otherwise

   ./bin/scalabel --config ./data/config.yml
   

   Then, the server can be accessed at http://localhost:8686.

5. Get labels

   The collected labels can be directly downloaded from the project dashboard. The data can be follow bdd data format. After installing the requirements and setting up the paths of the bdd data toolkit, you can visualize the labels by

   python3 -m bdd_data.show_labels.py -l <your_downloaded_label_path.json>
