does this work if the seed is set externally? Ie.:

set.seed(12345)
one <- calculate(y, nsim = 1)
set.seed(12345)
two <- calculate(y, nsim = 1)

And is the global seed respected by mcmc() etc? The interface to providing the seed to TF might well have changed. it was always fiddly (especially in TFP)

The current parts that operate on the seed are

https://github.com/njtierney/greta/blob/tf2-poke-tf-fun/R/calculate.R#L206-L216

However it seems that this isn't getting input later, or something? My only main thought on this is that we need to do the setting of the seed part a bit later, perhaps inside the TF function part, perhaps here?

  values <- calculate_target_tensor_list(
    dag,
    fixed_greta_arrays,
    values,
    stochastic,
    target,
    nsim
  )

That function, calculate_target_tensor_list probably also needs to be wrapped in tf_function

It does seem that the random number generation aspect of TF has changed

https://www.tensorflow.org/guide/random_numbers#stateless_rngs

But this seems a bit wild to me in that you need to create a special function for controlling random number generation, rather than just having some way to manage the state outside like using seed = or set.seed ?

Might need to investigate if rstudio/tensorflow do anything to manage random seeds

njtierney commented 1 year ago

Ok, good news.

tensorflow::set_random_seed

Seems to be what we want for setting the global random seed (helpfile: https://tensorflow.rstudio.com/reference/tensorflow/set_random_seed.html)

I guess we replace instances of set.seed with tensorflow::set_random_seed ?

I'm not quite sure how this would interact with code like this

      # if an RNG seed was provided use it and reset the RNG on exiting
      if (!is.null(seed)) {
        if (!exists(".Random.seed", envir = .GlobalEnv, inherits = FALSE)) {
          runif(1)
        }

        r_seed <- get(".Random.seed", envir = .GlobalEnv)
        on.exit(assign(".Random.seed", r_seed, envir = .GlobalEnv))
        set.seed(seed)
      }

or

# get the next seed as a L'Ecuyer
future_seed <- function() {
  okind <- RNGkind()[1]
  on.exit(RNGkind(okind), add = TRUE)
  RNGkind("L'Ecuyer-CMRG")
  .GlobalEnv$.Random.seed
}

So replacing set.seed in calculate here: https://github.com/njtierney/greta/blob/tf2-poke-tf-fun/R/calculate.R#L214

with tensorflow::set_random_seed(seed) now means this succeeds all tests in test_calculate

It also passes the check above:

#> ℹ Initialising python and checking dependencies, this may take a moment.

# fix variable
a <- normal(0, 1)
y <- normal(a, 1, dim = c(1, 3))

# the samples should be the same if the seed is the same
one <- calculate(y, nsim = 1, seed = 12345)

So perhaps that is all we needed to do? I'm not sure what the boilerplate code about extracting RNG seed from the global environment does so I'm a bit unsure about that part is all

goldingn commented 1 year ago

OK cool! I think you want both, actually. Set the R seed (to make sure it updates) and set the TF seed to the same thing.

But rather than setting the TF seed there, we probably want to set the R seed there, and then set the TF seed (to whatever the R seed is) just before execution of the TF code. that way it works either if the user passes a seed to the function, or sets the global R seed.

goldingn commented 1 year ago

[update from offline convo - tensorflow::set_random_seed(seed) sets the R seed as well as the TF one, so this should work]

Resolved by https://github.com/njtierney/greta/commit/5c057f0ee79a5218ca91e87b6a50c189d1c1d248

njtierney commented 1 year ago

Ack, actually I'm not sure if this is resolved now, based on this behaviour - which is, I would expect in all of these scenarios for setting the seed to work when it is set outside with set.seed or with the seed argument.

Instead
