Failed to read token [started at file position -1] at nnet2

[Iris Luo]

Hi, I'm an undergraduate from China. Recently I have met a problem when running the nnet2 script.

Here is the error message:

# nnet-combine-fast --initial-model=100000 --num-lbfgs-iters=40 --use-gpu=no --num-threads=8 --verbose=3 --minibatch-size=512 "" ark:exp/nnet2_online/nnet_ms_a/egs/combine.egs exp/nnet2_online/nnet_ms_a/final.mdl

I'll be very grateful if someone can give me some advice.

there is a scripting problem.  In the place in the command line where the arg is "", a list of input models is expected.
