Hello @matthew-burnard,

Could you please add fp16: True in the config file, i.e. configs/transformer_reverse.yaml or configs/rnn_reverse.yaml, and try to run the same train command again?

training:
    [...]
    use_cuda: False
    print_valid_sents: [0, 3, 6]
    keep_best_ckpts: 2
    fp16: True                        # <- add this line!

In my CPU environment, I've confirmed it works with the modification above:

Sorry, I haven't tested it in CPU before. And we know the tutorial is kind of outdated. We are working on the tutorial update for joey version 2, but it will take more time...

reminder for myself:

  • force to assign fp16 = True, if use_cuda = False
  • update reverse task config files to use fp16
  • update reverse task tutorial

Confirmed that this solves the problem on my end.
