9 months ago Hi,
I'm not sure why, but it seems it doesn't enter the correct if statement in the file montepython/likelihood_class.py on line 2515 (in the public version, yours might differ, but it is around this line:
if self.create_fid == True:
# Calculate relevant flat fiducial quantitiesUnder this if statement it creates the file that is missing, which it tries to load on the official version line 2541 (yours appears to be 2534)
fiducial = np.loadtxt('data/sdss_lrgDR7/sdss_lrgDR7_fiducialmodel.dat')
The solution would be to understand why it doesn't enter this if statement and force it to if necessary.
Best, Thejs

Hello！Dear professor. I'am a student studying cosmology. Now I am working on a project which need to do MCMC analysis with the LSS data, such as the sdss IrgDR7. But i meet some problem when i use the sdss lrgDR7. When i input the command:
python MontePython.py run -p /home/xiapengbo/montepython_public-3.5/input/sdss_lrgDR7.param -o /home/xiapengbo/montepython_public-3.5/output/cotton4 -N 10000000 --update 50 --superupdate 20 -f 0.7 --conf /home/xiapengbo/montepython_public-3.5/my.conf
there will be a error that :
Traceback (most recent call last): File "/home/xiapengbo/montepython_public-3.5/montepython/MontePython.py", line 40, in
sys.exit(run())
File "/home/xiapengbo/montepython_public-3.5/montepython/run.py", line 45, in run

raise IOError("%s not found." % path)
OSError: data/sdss_lrgDR7/sdss_lrgDR7_fiducialmodel.dat not found.
it is quit stranger that in the data file in its likehood shows it should automatically create the fiducialmodel to accelerated calculation. But actually there will not be.
I am very confused and unable to solve this problem. I will be very appreciate if you can solve this problem in your busy time.
