Hi, I met a problem that I can't solve. Could you please help look at this issus. Thx a lot! It may occur at traning.py line 184 as below:

while True: try: results = sess.run(ops)

More detail: InvalidArgumentError seq_lens(13) < 0 [[Node: clinical_concept_extraction/copy_0/cond_2/ReverseSequence = ReverseSequence[T=DT_INT32, Tlen=DT_INT32, batch_dim=0, seq_dim=1, _device="/job:localhost/replica:0/task:0/device:CPU:0"](clinical_concept_extraction/copy_0/cond_2/rnn/transpose_1, clinical_concept_extraction/copy_0/cond_1/sub)]]
