Dec 03, 2018 · TextCNN with PyTorch and Torchtext on Colab. PyTorch is a really powerful framework to build the machine learning models. Although some features is missing when compared with TensorFlow (For example, the early stop function, History to draw plot), its code style is more intuitive. Torchtext is a NLP package which is also made by pytorch team.
