smartmanuscript.application crash on fresh install develop branch #2

Open marcoleewow opened 5 years ago

Hi, application.py still seem to crash when doing some normalisation in preprocessing. Here is my traceback. I have installed the packages on the requirements.txt + tensor2tensor 1.5.3 which is required but not on the file.
