These rules are prefix searches, infix searches, postfix searches, URL searches, and defining special cases. The below code is an example of creating a tokenizer class.This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below.

We also demonstrate how to customized validation on the data content through this example. In the forward method of the Preprocess worker, we firstly check the key of the input, then try to decode the str and load it into array. The tutorial guides how we can use pre-trained GloVe (Global Vectors) embeddings available from the torchtext python module for text classification networks designed using PyTorch (Python Deep Learning Library).
