Hi, When I run the “8schools” example found at https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started I get the following error: “Error: vector memory exhausted (limit reached?).” I have reinstalled R and added “R_MAX_VSIZE=100Gb” (I have used R_MAX_VSIZE ranging from 10 to 100Gb) to the .Re…

I do not believe that it is running out of RAM during the compiling of the package. install.packages(“rstan”, repos = “ https://cloud.r-project.org/ ”, dependencies = TRUE) trying URL ‘ https://cloud.r-project.org/bin/macosx/el-capitan/contrib/3.5/rstan_2.18.2.tgz ’ Content type ‘application/x-gzip…

The stan call combines compilation and sampling. What happens if you do sm <- stan_model("~/Desktop/8schools.stan") to only compile it?

sm <- stan_model("~/Desktop/8schools.stan") does not produce any errors and creates a “Formal class stanmodel.”

And then post <- sampling(sm, data = schools_dat) runs out of RAM?

Yes, that line produces “Error: vector memory exhausted (limit reached?).”

OK, the 8 schools example is tiny, so my guess is that the compiler build something with a memory leak somehow. Can you try building it with clang++ rather than g++-8 in your ~/.R/Makevars file?

Thank you for your help! Unfortunately, no change with using a clang compiler. I have completed a fresh install of Mojave, command line tools, R, and RStudio. Rstan from Source: > install.packages(“rstan”, type = “source”) trying URL ‘ https://cran.rstudio.com/src/contrib/rstan_2.18.2.tar.gz ’ Co…

Do you still have LDFLAGS=-L/usr/local/Cellar/gcc/8.2.0/lib in ~/.R/Makevars? It is running into a linker error now.

Hi, I’m resurrecting this thread because I ran into the same error. I have tried all the suggested steps above, still run into the same error: > fit <- stan(file = '8schools.stan', data = schools_dat) Error: vector memory exhausted (limit reached?) My session info: > sessionInfo() R version 3.6.…

Do you run out of RAM as it is compiling or as it is sampling?
