Crashes on help example

[robjhyndman]

Any idea what is going on here. The example is taken from help(fable.prophet::prophet).

[robjhyndman]

Here it is, running in a terminal.

I can't reproduce this, what package versions are you using?

library(fable.prophet)
#> Loading required package: Rcpp
#> Loading required package: fabletools
library(tsibble)
as_tsibble(USAccDeaths) %>%
  model(
    prophet = prophet(value ~ season("year", 4, type = "multiplicative"))

prophet v0.6.1 (from CRAN) and fable.prophet v 0.1.0.9000 (from github)

It looks like it is a prophet problem, as I get the same issue running the example in the help for prophet::prophet.

[mitchelloharawild]

Hmm, I'm using prophet v0.6.1 without issue. What's your version of {rstan}?

[robjhyndman]

rstan v2.12.2. The problem seems to have been resolved by updating prophet to the dev version. Possibly related to this commit: https://github.com/facebook/prophet/commit/d7cd1f299dc773f35a6c79bc6eaaaea314638d20#diff-8c2574892063f995fdf756bce07f46c1a5193e54cd52837ed91e32008ccf41ac

[mitchelloharawild]

I'm using {rstan} v2.21.2 without issue.
