Pymultinest error with missing positional argument 'lnew'

[bking-astro]

Traceback (most recent call last): File "/usr/projects/nsmergers/conda_nmma/lib/python3.11/site-packages/pymultinest/run.py", line 221, in loglike return LogLikelihood(cube, ndim, nparams) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ TypeError: solve..SafeLoglikelihood() missing 1 required positional argument: 'lnew' Exception ignored on calling ctypes callback function: <function run..loglike at 0x7f3424eeea20>

Describe the bug When I run light_curve_analysis with the command below and the outdir doesn't exist, I get the error above. Then the command fails with the error below:

To Reproduce Steps to reproduce the behavior:

1. Download Michael's trained model on LANL files

2. Run command: light_curve_analysis --model LANL2022 --svd-path /lustre/scratch4/turquoise/bking/nmma_test/svdmodels/ --filters 2massh,2massj,2massks,atlasc,atlaso,bessellb,besselli,bessellr,bessellux,bessellv,ps1g,ps1i,ps1r,ps1y,ps1z,sdssu,uvotb,uvotu,uvotuvm2,uvotuvw1,uvotuvw2,uvotv,uvotwhite,ztfg,ztfi,ztfr --verbose --local-only --interpolation_type sklearn_gp --outdir /lustre/scratch4/turquoise/bking/nmma_test/outdir/LANLTP1 --label TP1 --prior /lustre/scratch4/turquoise/bking/nmma_test/nmma/priors/LANL2022.prior --tmin 0. --tmax 21 --dt 0.1 --error-budget 1 --nlive 512 --Ebv-max 0 --trigger-time 59397.28347219899 --injection /lustre/scratch4/turquoise/bking/nmma_test/outdir/LANLTP1/injection.json --injection-num 0 --injection-outfile /lustre/scratch4/turquoise/bking/nmma_test/outdir/LANLTP1/lc.csv --generation-seed 42 --plot

Platform information:

• NMMA version: (i.e. current commit)
• Platform: run on Chicoma

Additional context If I run with the flag --sampler dynesty I do not see this problem

@tsunhopang Any ideas? pymultinest issue?

@bking-astro I used to get similar errors but it was mostly due to some incorrect initialisation or using same output dir as last garbage run, etc. But here I am curious to know about the location of injection input file, outputdir, and injection outfile. All three have same base path: /lustre/scratch4/turquoise/bking/nmma_test/outdir/LANLTP1. Shouldn't the path to your input inejction be one folder up relative to the output directory? Or it maybe anywhere else as well. But input can't be inside the folder which is not yet created. Or maybe I am missing something

This problem found to be related to broken pymultinest installation
