Hi all,
I am trying to install CmdStanR on Windows 10. I have installed cmdstan via a Conda environment and can get the example model to compile but not sample. I am having very similar problems to here.
file <- file.path(cmdstan_path(), "examples", "bernoulli", "bernoulli.stan")
# compile model
mod <- cmdstan_model(file) # this works fine!
# sampling
data_list <- list(N = 10, y = c(0,1,0,0,0,0,0,0,0,1))
fit <- mod$sample( # this does not!
data = data_list,
seed = 123,
chains = 4,
parallel_chains = 4,
refresh = 500
)
But this fails with the following error.
Running MCMC with 4 parallel chains...
Warning: Chain 1 finished unexpectedly!
Warning: Chain 2 finished unexpectedly!
Warning: Chain 3 finished unexpectedly!
Warning: Chain 4 finished unexpectedly!
Warning: Use read_cmdstan_csv() to read the results of the failed chains.
Warning messages:
1: All chains finished unexpectedly! Use the $output(chain_id) method for more information.
2: No chains finished successfully. Unable to retrieve the fit.
Following the error messages I ran fit$output_files() but there were no csv files (i.e. the output read character(0). I thought maybe it had something to do with the parallel chains, but removing this option has no effect on the error message.
I have also tried
fit <- cmdstanr_example(chains = 1)
but this fails with a similar error.
Any ideas as to what could be the problem here? Thank you in advance.
