Windows Installation¶
The SpacePy team currently provides binary “wheels” via PyPI so it can
be installed on Windows without a compiler. Binaries are provided for
Python 2.7, 3.6, and 3.7 in 64-bit and 32-bit variants for each. pip
install spacepy
should find and install these binaries.
Our recommended (but not required) Python distribution is Anaconda running 64-bit Python 3. Anaconda includes much of the scientific Python stack. Another excellent distribution is Canopy.
You may need to install the dependencies some way other than pip; for example, if you are running an earlier version of Python. The latest version of many dependencies requires Python 3.6 and pip will not install older versions to get around this. See Dependencies via conda.
Fortran and ffnet¶
ffnet is required for
LANLstar
. It can be installed either before or after
SpacePy. Binary wheels are not provided, so a Fortran compiler is
required
With Anaconda, the compiler and ffnet can be installed with:
conda install m2w64-gcc-fortran libpython
SET FC_VENDOR=gfortran
pip install ffnet
The FC_VENDOR line is necessary because ffnet defaults to the Microsoft compiler.
Some standalone binary installers (no pip
support) are also
available on the ffnet site. These do not require a
compiler but support only a limited set of Python versions.
Compiling¶
If a binary wheel is not available for your version of Python, pip
will try to compile SpacePy. The only supported compiler is
mingw32
. Install it with:
conda install m2w64-gcc-fortran libpython
This is also required if installing from a source distribution or git checkout.
irbempy
requires Fortran to compile and the only
supported compiler is gnu95
; this is the default and provided
by m2w64-gcc-fortran
.
If you have difficulties, it may be useful to reference the build scripts <https://github.com/spacepy/spacepy/tree/master/developer/scripts> the SpacePy developers use.
NASA CDF¶
pycdf
requires the NASA CDF library . Binary
installers are available for Windows; be sure to pick the version
that matches your Python installation. The current 32-bit version
is cdf37_1_0-setup-32.exe;
for 64-bit, cdf37_1_0-setup-64.exe.
This is a simple self-extracting installer that can be installed either before or after installing SpacePy.
Standalone installers¶
Self-extracting and self-installing executables are also available for
download direct from our github. Be sure to choose the
file that matches your Python installation, both in Python version and
word size (64-bit vs. 32-bit.)
E.g. spacepy-0.2.0.win-amd64.py36.exe
is the installer for Python
3.6 on 64-bit Windows and spacepy-0.2.0.win32.py27.exe
is the
installer for Python 2.7 on 32-bit Windows.
Once downloaded, these can be installed without an internet connection.
If using these installers, the SpacePy Dependencies will not be installed automatically.
Dependencies via conda¶
Installation via pip
will automatically install most Python
dependencies (but not ffnet or the NASA
CDF library). They can also be installed from conda:
conda install numpy scipy matplotlib networkx h5py
Standalone dependencies¶
Most of the SpacePy Dependencies have Windows installers available via
their pages, but pip
or conda
are recommended instead.
Developers¶
If you want to build the documentation yourself (rather than using the documentation shipped with SpacePy), install sphinx and numpydoc. The easiest way is via pip:
pip install sphinx numpydoc
They are also available via conda:
conda install sphinx numpydoc
