[LealemTilahun]

Hi @sgrvinod, i tried to run eval.py but "ValueError: max() arg is an empty sequence" error msg is displaying. how can i fix this error please!

You can set beam_size at a big num,maybe it will work.

And once I have meet this problem,can not evaluate it at beam_size=5,after I train an other model at same parameters,it is work!

A bigger beam size yields another problem. What if you have trained a model in the same parameters, but with a different dataset?

Was the ValueError issue resolved? If yes, then how?

Thanks.

Hello! Make sure you are assigning the latest .json file generated to the data folder. If that doesn't work, try adding "img_as_float" while reading the images in preprocessing and "img_as_ubyte" while resizing. Run create_input_files.py. Replace the files generated in the output folder to the ones already present in data folder and train again. This should solve the issue. Thanks!

Thanks for your reply. Actually，I tried to set beam_size=3，and it works. I will try your solution later.Thanks!
