class (in nbodykit) compiled under wrong compiler version

[VMBoehm]

For some cosmologies, computing pklin:

MADLens/MADLens/lightcone.py

Line 520 in 9f7817b

rho = rho.apply(lambda k, v:(cosmo.get_pklin(k.normp(2,zeromode=1) ** 0.5,0) / pm.BoxSize.prod()) ** 0.5 * v)

runs into this error
=>spectra_pk_at_z(L:418) :error in array_interpolate_spline(psp->ln_tau, psp->ln_tau_size, psp->ln_pk, psp->ddln_pk, psp->ln_k_size, ln_tau, &last_index, output_tot, psp->ln_k_size, psp->error_message);
=>array_interpolate_spline(L:1701) : x=9.782528e+00 > x_max=9.782528e+00

which is a well known class error:
https://github.com/lesgourg/class_public/search?q=array_interpolate_spline%28&type=Issues

proposed fix: update bccp conda environment under /global/common/software/m3035/conda-activate.sh 3.7 ?

Let's first try to fix class. lesgourg/class_public#309

[VMBoehm]

and the recompile N-bodykit? Let's hope they reply soon...

[VMBoehm]

have you looked into my workaround?

[rainwoodman]

We have a local fork of class inside classlss, and we can apply the patch there (https://github.com/nickhand/classylss/tree/master/depends) - Yu

I missed there was an error in the sqrt -- probably some negative numbers given by the interpolation. I see you closed it.

[rainwoodman]

Do you have a minimal example that reliably reproduces this with nbodykit's Cosmology object?

[rainwoodman]

@VMBoehm; I've added the patch to our class binding.

See if you update your classylss to the master branch the problem is gone:
(I think something like) bcast-pip https://github.com/nickhand/classylss/archive/master.zip

[VMBoehm]

seems to work in my test run that failed before. I'll start a bigger run today and close this if it works.

successfully created 300 maps at 300 different cosmologies!

[rainwoodman]

Yeah!
