Using pip or easy_install¶
You can use pip to install
slepc4py and its
mpi4py is optional but highly recommended):
$ pip install [--user] numpy mpi4py $ pip install [--user] petsc petsc4py $ pip install [--user] slepc slepc4py
Alternatively, you can use easy_install (deprecated):
$ easy_install [--user] slepc4py
If you already have working PETSc and SLEPc installs, set environment
PETSC_DIR (and perhaps
PETSC_ARCH for non-prefix installs) to appropriate values
and next use pip:
$ export SLEPC_DIR=/path/to/slepc $ export PETSC_DIR=/path/to/petsc $ export PETSC_ARCH=arch-linux2-c-opt $ pip install [--user] petsc4py slepc4py
You need to have the following software properly installed in order to build SLEPc for Python:
- Any MPI implementation  (e.g., MPICH or Open MPI), built with shared libraries.
- A matching version of PETSc built with shared libraries.
- A matching version of SLEPc built with shared libraries.
- NumPy package.
- petsc4py package.
|||Unless you have appropriately configured and built SLEPc and
PETSc without MPI (configure option |
|||You may need to use a parallelized version of the Python interpreter with some MPI-1 implementations (e.g. MPICH1).|
The SLEPc for Python package is available for download at the Python Package Index. You can use curl or wget to get a release tarball.
$ curl -LO https://pypi.io/packages/source/s/slepc4py/slepc4py-X.Y.Z.tar.gz
$ wget https://pypi.io/packages/source/s/slepc4py/slepc4py-X.Y.Z.tar.gz
After unpacking the release tarball:
$ tar -zxf slepc4py-X.Y.tar.gz $ cd slepc4py-X.Y
the distribution is ready for building.
Mac OS X users employing a Python distribution built
with universal binaries may need to set the environment
ARCHFLAGS to appropriate values. As an example,
assume your Mac is running Snow Leopard on a 64-bit Intel
processor and you want to override the hard-wired cross-development
SDK in Python configuration, your environment should be modified
$ export MACOSX_DEPLOYMENT_TARGET=10.6 $ export SDKROOT=/ $ export ARCHFLAGS='-arch x86_64'
Some environment configuration is needed to inform the location of
PETSc and SLEPc. You can set (using setenv,
export or what applies to you shell or system) the
PETSC_ARCH indicating where you have built/installed SLEPc
$ export SLEPC_DIR=/usr/local/slepc $ export PETSC_DIR=/usr/local/petsc $ export PETSC_ARCH=arch-linux2-c-opt
Alternatively, you can edit the file
setup.cfg and provide the
required information below the
[config] slepc_dir = /usr/local/slepc petsc_dir = /usr/local/petsc petsc_arch = arch-linux2-c-opt ...
Finally, you can build the distribution by typing:
$ python setup.py build
After building, the distribution is ready for installation.
If you have root privileges (either by log-in as the root user of by using sudo) and you want to install SLEPc for Python in your system for all users, just do:
$ python setup.py install
The previous steps will install the
slepc4py package at standard
If you do not have root privileges or you want to install SLEPc for Python for your private use, just do:
$ python setup.py install --user
