models: rc: transformer models: confidence returning code has introduced some bugs #21
Description
- While fixing models: rc: transformer models: return confidence with prediction if possible #17 this bug was introduced
- The answer returned by the model has white-spaces in between letters of a single word, like 'apple' would be returned as 'a p p l e'
- It cannot handle the cases where start token occurs after the end token and thus no answer is returned in such cases.
