There may be a typo in the simple example of an lstm.yml

[KingAndQueen]

In the simple example of an lstm.yml:
"files: # assign files to reference name
states: cbt_epoch10.h5 # HDF5 files have to end with .h5 or .hdf5 !!!
word_ids: train.h5 ------- # May be you mean train: train.h5
words: words.dict # dict files have to end with .dict !!
"
Since the following word_sequence cannot find the train file
"word_sequence: # defines the word sequence
file: train # HDF5 file
"

I am not sure about this, please confirm
