Solved #53 (comment)

In PyTorch 1.4.x (index/128) at https://github.com/zhou13/lcnn/blob/88f281ab5421d51a62f1f84f97fea05afbf0c8d8/lcnn/models/line_vectorizer.py#L174 outputs integer values but in PyTorch 1.8.x it outputs float values. Updating it with (index//128) outputs integer values in both PyTorch versions and solves #53 (comment).
