cmdstanpy Stan Model not compiling with external c++

Summary:

Attempting a minimal example of compiling against external c++ code from this example

Description:

Using a Stan model of

functions {
  real make_odds(real theta);
}
data {
  int<lower=0> N;
  array[N] int<lower=0, upper=1> y;
}
parameters {
  real<lower=0, upper=1> theta;
}
model {
  theta ~ beta(1, 1); // uniform prior on interval 0, 1
  y ~ bernoulli(theta);
}
generated quantities {
  real odds;
  odds = make_odds(theta);
}

and an external bernoulli.hpp:

#include <boost/math/tools/promotion.hpp>
#include <ostream>

namespace bernoulli_model_namespace {
    template <typename T0__>  inline  typename
          boost::math::tools::promote_args<T0__>::type
          make_odds(const T0__& theta, std::ostream* pstream__) {
            return theta / (1 - theta);
       }
}

I get a

(where I replaced the actual directory structure on my computer with ...).

I ran cmdstanpy.rebuild_cmdstan() and the issue persists.

Can you enable debug logging (https://mc-stan.org/cmdstanpy/users-guide/outputs.html#logging) and post the output that yields?

Sep 02 '22 20:09 mathDR

It appears that the compiler is not finding the make_odds.hpp file? Is it not supposed to reside in the same directory as the stan file?

Sep 02 '22 20:09 mathDR

error: invalid value 'precompiled-header' in '-x precompiled-header'

This is not an error I've ever seen before. Could you try running os.environ['PRECOMPILED_HEADERS'] = 'false' and trying again with the debug logging?

Sep 06 '22 14:09 WardBrian

Hey @WardBrian I am on PTO this week, but will report back early next!

Sep 07 '22 03:09 mathDR

Okay I am back. Here is the all.log with os.environ['PRECOMPILED_HEADERS'] = 'false':

Huh, that's a new one for me. Can you try changing the hpp file to use stan::promote_args_t<T0__> instead of typename boost::math::tools::promote_args as the return type? I'm not sure why this would make a difference, but I know that that Stan has switched to using that more

Sep 12 '22 13:09 WardBrian

@WardBrian Unfortunately my computer died this morning. I am getting a replacement, but that will be a macbook pro M1 chip, so I may not be able to reproduce this issue. I will run the example when I get my new machine and report back.

Sep 13 '22 00:09 mathDR

Okay I think the same error is plaguing me on my new Apple M1.

What I have done: external_bernoulli.stan:

functions {
  real make_odds(real theta);
}
data {
  int<lower=0> N;
  array[N] int<lower=0, upper=1> y;
}
parameters {
  real<lower=0, upper=1> theta;
}
model {
  theta ~ beta(1, 1); // uniform prior on interval 0, 1
  y ~ bernoulli(theta);
}
generated quantities {
  real odds;
  odds = make_odds(theta);
}

make_odds.hpp:

#include <stan/model/model_header.hpp>
#include <ostream>

namespace bernoulli_model_namespace {
  template <typename T0__,
            stan::require_all_t<stan::is_stan_scalar<T0__>>* = nullptr>
    stan::promote_args_t<T0__>
    make_odds(const T0__& theta, std::ostream* pstream__) {
      return theta / (1. - theta);
    }
}

Then I run

model_external = CmdStanModel(
    stan_file='external_bernoulli.stan',
    user_header='make_odds.hpp',
)

and get

I'm going to ping @rok-cesnovar on this. I believe he has an M1 Mac to mirror your example on

Sep 14 '22 19:09 WardBrian

Okay. Do you want me to open a new issue?

Sep 14 '22 19:09 mathDR

I think it is fine to leave here for now, if we determine it belongs somewhere better like the CmdStan repo we can transfer it then.

Sep 14 '22 19:09 WardBrian

Hi @mathDR - if you're still facing this issue, I just wanted to alert you to the fact that recent versions of Stan have changed how external C++ is handled in such a way that should have fixed this. The CmdStan documentation has been updated here: https://mc-stan.org/docs/cmdstan-guide/using-external-cpp-code.html

THANK YOU!!!
