I downloaded cmdstanr today to get the latest version, 0.0.0.9008.
I tried a basic model
parameters {
real phi;
}
model {
phi ~ normal(0, 1);
}
I then run it as follows
sim <- mod$sample()
and get the following message
All 4 chains finished successfully.
Mean chain execution time: 0.1 seconds.
Total execution time: 0.5 seconds.
Error: Can't subset columns that don't exist.
x The columns `lp__`, `treedepth__`, and `divergent__` don't exist.
Run `rlang::last_error()` to see where the error occurred.
What is going on? This is as standard a use of cmdstanr as it gets…
Sooooo… I updated R and all the packages (which is a rather tedious process) and found out posterior is not available for R v4.0.2. Is there a workaround this?
@charlesm93 this is unfortunate, sorry! I don’t have any idea why vroom would have an issue with R 3.6 and mac (I haven’t seen that reported anywhere related to vroom and it was definitely working for me with R 3.6 and Mac last week before I updated to R 4.0).
When it says
Run `rlang::last_error()` to see where the error occurred.
