I’m attempting to speed up model fitting by specifying the “threads” argument in brms. However, when I do so I receive the following error (at least, I think this is the only/relevant error. I find the output from compilation baffling, so I’m not sure what’s relevant):

Error: An error occured during compilation! See the message above for more information.
I’m able to replicate this error with a simple model, as well as with my own data.
brm(Sepal.Width ~ Sepal.Length, data = iris, chains = 3, threads = 3, cores = 3, backend = 'cmdstanr')
If I remove the threads = 3
argument the model compiles and runs fine.
I’ve installed cmdstan using the Conda installation instructions for Windows 10 and am using a conda environment with reticulate to work with the package in R. I tried using rebuild_cmdstan()
, but that seemed to just bork my cmdstan installation and no models would compile, so I had to reinstall cmdstan with conda.
