Error in root/src/tools/predict.ipynb

[KoushikMSD]

I was going through all the steps with the pre-trained model.I downloaded dataset5 from the the project website,which contains "data_props.pkl" file, but when I use this to run
python run.py -a 0.0001 -e -1 -b 25 -v -1 -i 2 --r-lambda 0.00005 --raw-data-folder C:\Users\Koushik/predictions\inferencing_50 --test --save-all-eval --restore C:\Users\Koushik/predictions\logdir --image-folder C:\Users\Koushik/predictions/formula_images as described in the notebook predict.ipynb I got an error - raise ParamsValueError('%s is not a valid value of property %s'%(val, name))
commons.dl_commons.ParamsValueError: 338 is not a valid value of property CTCBlankTokenID
Can someone please guide me to get rid of that ?
