I have recently updated rstan (version 2.26.4) and R (version 4.1.2). Running expose_stan_functions now throws the following error: “Error: $ operator is invalid for atomic vectors” An example: model_code <- ' functions { real standard_normal_rng() { return normal_rng(0,1); } }…

The error comes from the underlying call to rstan::expose_stan_functions which brms::expose_functions is a wrapper for. It can be caused by a few things, but the main culprits are usually a version of withr > 2.2.0 or an out of date installation of RcppParallel. First try: remotes::install_versio…

Hi @ajnafa Many thanks for the reply. Unfortunately the error persists even after installing withr version 2.2.0 followed by updating RcppParallel and reinstalling rstan and StanHeaders remotes::install_version("withr", version="2.2.0") remotes::install_github("RcppCore/RcppParallel") remove.pac…

I believe the culprit here might be the new StanHeaders/rstan itself. @hsbadr I can replicate the error on a fresh install of 2.26.4 using the example code: model_code <- ' functions { real standard_normal_rng() { return normal_rng(0,1); } } ' expose_stan_functions(stanc(model…

v2.26.5 is ready for testing. remove.packages(c("rstan", "StanHeaders")) install.packages("rstan", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))

Same error is present, but I believe it’s separate from the TBB. I stepped through the expose_stan_functions source and it turns out that the Rcpp::sourceCpp call was returning an error: In file included from C:/Users/Andrew Johnson/Documents/R/win-library/4.1/StanHeaders/include/src/stan/model/mod…

To confirm that this is related to TBB or not, could you test v2.26.6? remove.packages(c("rstan", "StanHeaders")) install.packages("StanHeaders", repos = c("https://mc-stan.org/r-packages/", getOption("repos"))) install.packages("rstan", \repos = c("https://mc-stan.org/r-packages/", getOption("repo…

[image] andrjohns: error: 'validate_dims' is not a member of 'stan::io' stan::io::validate_dims(*this, stage, name, base_type, dims_declared); This looks like a USE_STANC3 issue where the headers are incompatible (v2.21 vs v2.26). I have no problem running expose_stan_functions() on my s…
