Installing airspeed velocity¶
airspeed velocity is known to work on Linux, Mac OS-X, and Windows. It is known to work with Python 2.7, 3.4, 3.5, and 3.6. It works also with PyPy.
airspeed velocity is a standard Python package, and the latest released version may be installed in the standard way from PyPI:
pip install asv
The development version can be installed by cloning the source
repository and running pip install .
inside it, or by pip
install git+https://github.com/airspeed-velocity/asv
.
The requirements should be automatically installed. If they aren’t installed automatically, for example due to networking restrictions, the requirements are:
- six, 1.4 or later
and one of the following:
virtualenv, 1.10 or later (it is required also on Python 3, where virtualenv is included as venv, since venv is not compatible with other versions of Python).
Note that virtualenv 1.11.0 will not work, as it contains a bug in setuptools that prevents its installation in a clean virtual environment.
An anaconda or miniconda installation, with the
conda
command available on your path.
Note
Anaconda or miniconda is preferred if the dependencies of your
project involve a lot of compiled C/C++ extensions and are
available in the conda
repository, since conda
will be able
to fetch precompiled binaries for these dependencies in many cases.
Using virtualenv
, dependencies without precompiled wheels
usually have to be compiled every time the environments are set up.
Optional optimization¶
If your project being benchmarked contains C, C++, Objective-C or
Cython, consider installing ccache
. ccache is a compiler cache that speeds up
compilation time when the same objects are repeatedly compiled. In
airspeed velocity, the project being benchmarked is recompiled at
many different points in its history, often with only minor changes to
the source code, so ccache
can help speed up the total benchmarking
time considerably.
