UndefRefError: access to undefined reference #6

Closed amellnik closed 6 years ago

amellnik commented 6 years ago

I'm on Flux 0.5.1 and FluxJS 0.1. I'm getting lots of UndefRefError: access to undefined reference except for the most trivial uses. This seems to be working for others on the same so I'm not sure what's going on. 

# Works
x = rand(10)
@code_js identity(x)
let model = (function () {
  let math = dl.ENV.math;
  function model(owl) {
    return owl;
  };
  model.weights = [];
  return model;
})();
flux.fetchWeights("model.bson").then((function (ws) {
  return model.weights = ws;
}));
# From the readme but doesn't work
x = rand(10)
m = Chain(Dense(10,5,relu),Dense(5,2),softmax)
@code_js m(x)

Seems to be the same as #5

MikeInnes commented 6 years ago

Let me know if checking out astinterpreter doesn't work for you. Otherwise, I've added a note to the readme so this doesn't keep tripping people up.

amellnik commented 6 years ago

Whoops, not sure how I missed #5 -- thanks.
