How to Install BARK¶
This section describes the prerequisites and installation-steps of BARK.
- Bazel > 3(requires Java)
- Python3.7 (
sudo apt-get install python3.7 python3.7-dev python3.7-tk)
- Virtual Env (
pip3 install virtualenv==16.7.8) (note that the newest version does not seem to link the Python.h)
- gcc7 (needs to be set as the default compiler)
- Visual Studio Code
Install using pip¶
- pip3 install bark-simulator
Setup on Linux¶
Optional: We recommend to use Anaconda. This way, you can create a clean python environment. After installation, create a conda env
conda create --name bark_python_env python=3.7 and follow with activating it:
conda activate bark_python_env. You can now proceed with the following:
git clone https://github.com/bark-simulator/bark.gitor download the repository from this page.
bash install.sh: creates a virtual environment (located in python/venv) and installs all python packages
source dev_into.sh: activates the virtual environment (make sure to run this before bazel)
bazel test //...to validate that BARK is working.
- Finally, try one of the examples provided in BARK by running
bazel run //examples:merging.
Setup on MacOS¶
- Install pyenv:
brew install pyenv.
- Install a newer version of tcl-tk:
brew upgrade tcl-tk.
pyenv install python3.7-dev. If you run into trouble with TKInter have a look here.
- Set this as your global Python version:
pyenv global 3.7-dev.
- Also add this Python version to your
eval "$(pyenv init -)".
- Install an older version of the virtualenv package by running:
pip install virtualenv==16.7.8
- In order to set TKAgg as backend have a look here.
- Modify the file
virtualenv -p python ./python/venvinstead as python is now the pyenv version.
- Now you can follow the same steps as when using Linux.
Build Pip package¶
- Install twine using python3 -m pip install –user –upgrade twine
- Run script bash package.sh to build code, package and upload to pypi
Frequently Asked Questions (FAQs)¶

GCC: Interal Compiler Error: Killed (program cc1plus)¶
You might be running out of memory during the bazel build.
Try limiting the memory available to bark via
bazel build //... --local_ram_resources=HOST_RAM*.4 (or any other build or test call).
