I have tried for hours to install FiPy I've installed Pip and many other things to get it to work. Pip successfull installed many of the things I needed but I cannot get it to work for PySparse or FiPy. Why I try, to install PySparse I get an error:

$ pip install pysparse
Downloading/unpacking pysparse
  Could not find a version that satisfies the requirement pysparse (from versions: 1.1.1-dev, 1.2-dev, 1.2-dev202, 1.2-dev203, 1.2-dev213, 1.3-dev)
Cleaning up...
No distributions matching the version for pysparse
Storing debug log for failure in /Users/Emily/.pip/pip.log

and when I try to install FiPy I get this error:

$ pip install fipy
Downloading/unpacking fipy
  Downloading FiPy-3.1.tar.gz (5.7MB): 5.7MB downloaded
  Running setup.py (path:/private/var/folders/jt/gzhjdv8s1xb_v2b52lmr8bx00000gn/T/pip_build_Emily/fipy/setup.py) egg_info for package fipy

Can you please help? Please be specific because I am having a lot of trouble.

I've just encountered the same problems you did, and here are my work-arounds:

Pysparse: pip doesn't find the pysparse distribution in PyPI because it appears to not be a stable version (see e.g. Could not find a version that satisfies the requirement pytz for reference). To get around this you could use, as the link suggests,

pip install --pre pysparse

However, that didn't work for me--the installation failed. So I downloaded and installed pysparse manually from http://pysparse.sourceforge.net/index.html

FiPY: The error says "no module named ez_setup". If you install the python ez_setup module using pip the installation of FiPY should now work.

FiPY seems to be working for me now. Good luck!

  • PySparse can be `pip install`ed by ``` pip install -e git+http://git.code.sf.net/p/pysparse/git#egg=PySparse ``` – jeguyer Dec 05 '14 at 18:45

PySparse is not a strict requirement for FiPy. FiPy needs one of PySparse, Scipy or Trilinos as a linear solver and Scipy is probably the easiest to install. To check that FiPy has access to a linear solver, you can run the tests,

$ python -c "import fipy; fipy.test()"

It should be evident from the test output if FiPy does not have a solver library available.
