Operating System : RHEL 7 RStan Version : 2.18.1 Output of writeLines(readLines(file.path(Sys.getenv("HOME"), ".R/Makevars"))): ▶ makevars Output of devtools::session_info("rstan") ▶ sessionInfo From rooting around on this forum, my impression has been that this error occurs when the compiled mod…

It isn’t exactly the size of the data but the size of the autodiff tree that may cause problems. Also, there is a long-standing Rcpp issue with giant lists needed to hold that many values that only @Krzysztof_Sakrejda has any understanding of. Does it generally work if you exclude the generated qua…

With include = FALSE, pars = c('O','P','D'), which are the generated quantities, the Title error still occurs. With pars = "", sample_file = "~/samples.csv", I get: ▶ log It asks me to rerun with 1 chain for debugging purposes, which generates one instance of no parameter ; sampling not done Thank…

[image] Peter_Adelman: With pars = "", sample_file = "~/samples.csv" , I get: I’m sorry. I meant to say pars = NA, include = FALSE, sample_file = "~/samples.csv" in order to exclude everything (except lp__). If that works, then you would have to do read_stan_csv() on the samples#.csv files in…

That does work for me! Thanks Let me know if there is anything else you would like me to test.

Does anyone have an idea about this? I am stumped and @Krzysztof_Sakrejda last logged on in March.

[image] Charles_Driver: Not sure, but perhaps see: Error in unserialize, rstan 2.18, problems with native mtune and march Thanks for the suggestion and I do agree the symptoms are similar. Unfortunately, the suggested fix (using -march=core2) does not seem to fix my issue. ▶ CPU info ▶ setdif…

I set up CmdStan and it compiled / appears to be running with a case that fails in rstan, which again implies that this problem is related to the Rcpp issue that @bgoodri mentioned earlier. I will just make a CmdStan shim that I use instead of rstan::stan().
