The easiest way to install Fuel is using the Python package manager
Fuel isn’t listed yet on the Python Package Index (PyPI), so you will
have to grab it directly from GitHub.
$ pip install git+git://github.com/mila-udem/fuel.git
This will give you the cutting-edge development version. The latest stable
release is in the
stable branch and can be installed as follows.
$ pip install git+git://github.com/mila-udem/fuel.git@stable
If you don’t have administrative rights, add the
--user switch to the
install commands to install the packages in your home folder. If you want to
update Fuel, simply repeat the first command with the
added to pull the latest version from GitHub.
Pip may try to install or update NumPy and SciPy if they are not present or
outdated. However, pip’s versions might not be linked to an optimized BLAS
implementation. To prevent this from happening make sure you update NumPy
and SciPy using your system’s package manager (e.g.
yum), or use a Python distribution like Anaconda, before installing
Fuel. You can also pass the
--no-deps switch and install all the
If the installation crashes with
ImportError: No module named
numpy.distutils.core, install NumPy and try again again.
Fuel’s requirements are
- PyYAML, to parse the configuration file
- six, to support both Python 2 and 3 with a single codebase
- h5py and PyTables for the HDF5 storage back-end
- pillow, providing PIL for image preprocessing
- Cython, for fast extensions
- pyzmq, to efficiently send data across processes
- picklable_itertools, for supporting iterator serialization
- SciPy, to read from MATLAB’s .mat format
- requests, to download canonical datasets
nose2 is an optional requirement, used to run the tests.
If you want to work on Fuel’s development, your first step is to fork Fuel
on GitHub. You will now want to install your fork of Fuel in editable mode.
To install in your home directory, use the following command, replacing
with your own GitHub user name:
$ pip install -e email@example.com:USER/fuel.git#egg=fuel[test,docs] --src=$HOME
As with the usual installation, you can use
--no-deps if you
need to. You can now make changes in the
fuel directory created by pip,
push to your repository and make a pull request.
If you had already cloned the GitHub repository, you can use the following command from the folder you cloned Fuel to:
$ pip install -e file:.#egg=fuel[test,docs]
Fuel contains Cython extensions, which need to be recompiled if you update the Cython .pyx files. Each time these files are modified, you should run:
$ python setup.py build_ext --inplace
