installation issues? about python-fsps HOT 15 CLOSED

Hi @Nolaa. The package version installed by pip is unfortunately quite out of date and does not work with the most recent versions of FSPS, sorry about that. Please follow the "Installing development version" instructions at http://dan.iel.fm/python-fsps/current/installation.

Also, make sure you compile FSPS (following the instructions in the FSPS manual) before installing python-fsps. If you are still having problems with the SPS_HOME variable, try typing echo $SPS_HOME at the command line to make sure the variable is properly set.

@Nolaa, it looks like there is something wrong with your FSPS installation, or it is a very old version.

If you want to do a clean install of FSPS, you can do the following

cd ~
git clone https://github.com/cconroy20/fsps.git
export SPS_HOME="$HOME/fsps"
cd fsps/src
make clean
make all
./simple.exe

where the last line is to check that FSPS is properly installed - it should not result in any errors. You should also add the export SPS_HOME line to your bash_profile, as you've done before.

Then you should be able to do

cd ~
git clone https://github.com/dfm/python-fsps.git
cd python-fsps
python setup.py install

without any errors.

Hope this helps.

Oh no! What is your FSPS commit hash? There was a change to FSPS over the summer, where sf_theta was renamed sf_slope. The most recent FSPS/master is 6febb61. Having the most recent fsps should fix the build for numpy 1.8.2.

I don't know what's wrong with the numpy 1.10 build.

from python-fsps.

It looks like the numpy 1.10 build is having issues with wrapping the FSPS params structure. This kind of error pops up on the numpy issues list, where it is suggested that Fortran structures aren't supported at all in f2py! e.g. numpy/numpy#4645 any thoughts @dfm?

Also, I've been able to build python-FSPS with numpy 1.9.2, I think from homebrew

from python-fsps.

YES! working now -- I had tried the most recent git FSPS with numpy 1.10, and 1.8 and the older FSPS with numpy 1.10 and 1.8, but only tried the older version with 1.9.2 -- I still get f2py errors but python-fsps installs and runs which is all I care about right now ^__^ yay!

from python-fsps.

I have Numpy and SPS installed and have added the "SPS_HOME" as an environment variable to .bash_profile like this:

export SPS_HOME="/Users/najmeh/Research/Autumn2015/FSPSmodel-Charley_Coonroy/fsps-master"

Then I edited the makefile in the src directory.
But, when I try to install fsps using this command:

pip install fsps

I keep getting this error:

Collecting fsps
  Using cached fsps-0.1.1.tar.gz
    Complete output from command python setup.py egg_info:

        from fsps import __version__
      File "fsps/__init__.py", line 30, in <module>
        raise ImportError("You need to have the SPS_HOME environment variable")
    ImportError: You need to have the SPS_HOME environment variable

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-I1078Y/fsps

I have no idea how to fix it. Any help on that will be appreciated.

Thanks for your comment @bd-j. About SPS_HOME variable, actually I used echo $SPS_HOME every time before doing any thing else.
After compiling FSPS by typing make in the src directory,
this time I get another error about fsps

bash-3.2$ echo $SPS_HOME

Thank you very much @bd-j . It did work, the only thing is every time i open a new terminal, I need to type export SPS_HOME="$HOME/fsps" before running python.

from python-fsps.

glad that worked, you might have to add the export SPS_HOME="$HOME/fsps" to .bashrc instead of .bash_profile to have it set all the time.

from python-fsps.

Actually, I did this before. What I just figured out is that I needed to change my default login shell to bash instead of typing bash ( to change the shell ) and then export SPS_HOME="$HOME/fsps" in .bashrc every time I open a new terminal. Now it is running!

Hi, Any updates on the numpy 1.10.1 build?

I blindly updated numpy to 1.10.1 too, and python-fsps failed the installation....Do I need to go back to Numpy 1.9 for now?

from python-fsps.

I haven't had time to build the numpy development version from source to make the check and write up an issue for numpy if it doesn't work. For now yes, v1.9.3 should work if you can get back to it.

from python-fsps.

see #49, this appears to be solved in numpy v1.11

from python-fsps.

It looks like numpy have backported the f2py fixes from 1.11 to at least 1.10.4, such that python-fsps succesfully compiles using the latest macports numpy version (which is 1.10.4). @nell-byler hope this helps.

from python-fsps.

Closing as the problems with numpy are gone in recent numpy versions.
