error in decoding with small batch sizes

[Pooya Rezaei]

I got the following error for batch size 5 and lower. I am trynig to use this for batch_size = 1 and I got the same thing. Any idea why?

python evaluate.py -model_path ../pretrained/pretrain.pt -batch_size 4

There are some 0 len layouts
Add this to evaluate:

js_list = [js for js in js_list if len(js['lay']) > 0]
