When I run lstmtraining as 

  /usr/bin/lstmtraining \
    --debug_interval 0  \
    --traineddata /usr/share/tesseract-ocr/4.00/tessdata/eng.traineddata \
    --continue_from /output/eng.lstm \
    --net_spec '[1,36,0,1 Ct3,3,16 Mp3,3 Lfys48 Lfx96 Lrx96 Lfx256 O1c111]' 
\
    --model_output /output/trained \
    --learning_rate 20e-4 \
    --train_listfile /input/train.files \
    --eval_listfile /input/eval.files \
    --max_iterations 5000


I'm only getting training error displayed in the stdout log eg:

At iteration 268/300/337, Mean rms=3.577%, delta=21.465%, char 
train=87.195%, word train=81.204%, skip ratio=12.333%,
New best char error = 87.195 wrote checkpoint.

Is the eval_listfile actually used for anything? I'm hoping to 
automatically perform model evaluation (ideally with early stopping) as 
part of the training process (i.e. without calling lstmeval).
