Cannot read property 'train' of undefined

If I try to run exactly the dead simple LSTM example posted here: https://github.com/cazala/synaptic/issues/217

I still get the error

const trainResults = lstm.trainer.train(trainSet, trainOptions);
                                ^

Do I have the wrong version of Node running maybe?

As a test I jumped back to synaptic version 1.0.0 and then the example from https://github.com/cazala/synaptic/issues/217 worked. Still not clear exactly why?

I got the same a while ago and used the XOR trainingset to test the basics, than rewrote my trainingset code from scratch. I must have had a bug in the creation of my trainingset and the recent Synaptic code is more bitchy to detect broken training data.

I just tried the exact same thing. It appears that the trainer property on the LSTM has been removed. Seems like you now much instantiate your own trainer, maybe something like this?

const network = new Architect.LSTM(2, 10, 2)
const trainer = new Trainer(network)
trainer.train(trainingData, options)

I can see that the v1.0.0 LSTM architect adds a trainer to the instance, and it no longer appears to.
