Multiple issues with expose_stan_functions. #458

dmenne · 2017-10-10T18:06:40Z

Summary:

Multiple issues with expose_stan_functions. This is a summary of

http://discourse.mc-stan.org/t/error-expose-stan-functions/2119/6

Description:

expose_stan_functions does not work with a stanc model passed. Works partially with a file
when used with file, compile error

Reproducible Steps:

Run the example "Not run" in documentation of expose_stan_function

Error in get_model_strcode(file, NULL) : 
      file must be a character string or connection

Your version works when the filename is given (checked), but does does not retrieve the mc-string you use in the example. Alternatively, remove the example in the documentation.

function (file, ...) 
{
    model_code <- get_model_strcode(file, NULL)
    model_cppname <- legitimate_model_name(basename(file), obfuscate_name = TRUE)

Something like this, probably

function (file, mc_code, ...) 
{
    model_code <- get_model_strcode(file, mc_code)

Also tried with RStudio on Ubuntu in addition to Windows

– Put fibonacci example in the documentation in a file “a.stan” (since passing text currently fails)

library(rstan)
st = expose_stan_functions("a.stan")

Using your #422

a.stan is your Fibonacci-Example code put in a file. For reasons why not used directly, see original post

Windows:

@dmenne you also need the matching rstan branch (currently a PR on rstan).

dmenne · 2017-10-17T15:18:05Z

So this is not enough?

devtools::install_github("stan-dev/rstan/rstan/rstan@feature/issue-422-standalone-functions-k")

sakrejda · 2017-10-17T15:31:19Z

I'm not sure what's going on with this, please try this:

Run with a specific cacheDir, for example: expose_stan_functions('a.stan', cacheDir='.')
Find two files in the cache directory post them here:
a) something like sourceCpp-x86_64-pc-linux-gnu-0.12.12/file1e8a6ab56566.cpp
b) and something like sourceCpp-x86_64-pc-linux-gnu-0.12.12/sourcecpp_1e8a55e87ddc/file1e8a940078f.cpp

The first file is the c++ generated by Stan and the second is the c++ generated by Rcpp, without those troubleshooting is sort of hopeless.

sakrejda · 2017-10-17T16:34:34Z

@dmenne so locally with both branches correctly installed:

rstan::expose_stan_functions('gah.stan', cacheDir='.')
fibonacci(5, rstan::OUT)
fibonacci(9, rstan::OUT)

Gets me this in the terminal:

> rstan::expose_stan_functions('gah.stan', cacheDir='.')
> fibonacci(5, rstan::OUT)
[1] 5
> fibonacci(9, rstan::OUT)
[1] 34

I think you're having an installation problem. So try reinstalling StanHeaders and then reinstalling rstan itself. We may need @bgoodri for help with this

dmenne · 2017-10-17T16:45:05Z

Does the example from the documentation of expose_stan_functions run ok on your installation ?

The Windows-Version
The ubuntu-Version

bgoodri · 2017-10-17T17:27:14Z

You may need to pull my latest push to develop to get that example to work with the master branches of Stan and Stan Math.

Strange. I work with RStan every day and have a current package on CRAN with it (breathteststan), so the installation cannot be totally foobar; and Ubuntu runs on an external Web server totally idependently.+

I re-installed StanHeader, but only from CRAN 2.16.0-1. No change. But maybe I have to get a github version? Which one?

Rstan needs to be reinstalled after stanheaders to pick up the right code. Also how about those c++ files that could actually tell us what's wrong?

Even works with the example in the docs! Thanks and over.

Sorry about my impatience I needed this for a pending release of breathteststan

@sakrejda Sorry, I just deleted them on my server, because I thought the issure was resolved. You still need them?

Just recovered them. Have to go not yet checked.
