Hello all. My model with reduce_sum_static fials to compile with the error that begins with the following (the entire error is really long): ROR:cmdstanpy:file model.stan, exception ERROR In file included from /include/c++/4.9.3/bits/move.h:57:0, from /include/c++/4.9.3/bits/stl_p…

Oh, so you only got the sysadmins to upgrade from 4.8 to 4.9.3? That is unfortunate as that is quite an old compiler (5years+). It should still work though. The generated C++ from your Stan model is complex and g++ 4.9.3 is not the most efficient with it so its default settings are not able to hand…

The model you supplied has a syntax error: functions { real partial_sum(real[] dummy, int start, int end, real[,] X, vector mu_prior_x, real sigma_v, matrix A, matrix B, real[,,] U, real Q, matrix C, real sigma_r, int[,,] pressed_gng…

So sorry, I attached the wrong model file. Even with w I get the same error. OS is centOS7 and C++ compiler is 4.9.3 model.txt (6.6 KB)

@syclik @stevebronder @Bob_Carpenter @bbbales2 @wds15 @tadej Just a heads up that we might really need to start thinking about setting the compiler bar a bit higher than g++ 4.9.3 or we will need to stop increasing compile-time complexity of our codebase. We might get around it with overriding de…

Yup. That’s what major version bumps can be used for.

[image] rok_cesnovar: Put CXXFLAGS_PROGRAM += -ftemplate-depth=2000 in your make/local. That’s super helpful! Is there a tutorial on how to make changes to make/local? Bc I saw I will have to edit make/local also to make MPI work. Thanks!

The instructions are: In your cmdstan folder (if you installed with cmdstanpy check the home folder for .cmdstanpy) you should find a folder named make. Create a file named local in it and put the above line in that file.

Linking to the previous discussion here The tl;dr is that if we want to bump up we should get C++17 along the way. we could bump up to gcc-7* and leave clang* as is. But to do this we need to fixup the pystan wheel builder so that it uses the python package docker builder with gcc-8. I’m for havi…

UPDATE - I updated to g++ 9.3.0 and the model compiled just fine, but I have a sampling error now: RuntimeError: Error during sampling. chain 1 returned error code -11 Should I recomplie cmdstan from scratch using g++ 9.3.0, or that’s fine using the cmdstan version I downloaded with g++ 4.9.3 load…

[image] nerpa: Should I recomplie cmdstan from scratch using g++ 9.3.0, or that’s fine using the cmdstan version I downloaded with g++ 4.9.3 loaded? You definitely need to recompile cmdstan.

Update 2 - the model compiles and begins to sample, but now exists with : raise RuntimeError(err_msg) RuntimeError: Error during sampling. chain 1 returned error code 70 Same happens for another model that worked just fine with g++ 4.9.3.

You definitely need to recompile cmdstan.
