Hi

This is the first time I install this software.
I have installed the default version (not the development one, after installing requirements, including fsps).
It seems that the code cannot find an important library file xsp_feh-2.00.spec
The problem raises at the step "get a source" after
CSPSpecBasis(zcontinuous=1)

I get the error:
Fixed Parameters: (name: value [, depends_on])

zred: [0.07260209]
sfh: [4]
imf_type: [2]
dust_type: [0]
add_neb_emission: [ True]
add_neb_continuum: [ True]
nebemlineinspec: [ True]
gas_logz: [0.] <function stellar_logzsol at 0x72a980ca5ca0>
gas_logu: [-2.]
SPS_SETUP ERROR: xsp_feh-2.00.spec cannot be opened

similarly, in the tutorial, when running
python demo_params.py --objid=0 --emcee --optimize --outfile=demo_obj0_emcee

I get the same error:
SPS_SETUP ERROR: xsp_feh-2.00.spec cannot be opened

This is an issue with the fsps installation. Can you try

echo $SPS_HOME
python -c "import fsps; print(fsps.__version__)"
cd $SPS_HOME
git rev-parse HEAD

Thank you. Here my output:

Thanks - the python-fsps version is a bit out of date, the current release is 0.4.6. Once you've updated it should work.

Thanks. I could install last version only after switching to python 3.10. Now it works :-) Sorry if I missed this requirement (maybe 3.9 was enough, but I did not check) :-(

Thanks for the info, I will try to make sure that requirement is noted.
