UNF(Universal NLP Framework) is built on pytorch and torchtext. Its design philosophy is：

• modularity: specifically, on the one hand, it is convenient to quickly run some nlp-related tasks; on the other hand, it is convenient for secondary development and research to implement some new models or technologies.
• efficiency: supports distributed training and half-precision training, which is convenient for quickly training the model, although the current support is relatively crude
• comprehensive: support pytorch trace into static graph, support c ++ server, provide web-server for debugging tools

Now, support text classification and sequence labeling related tasks.
