AllenNLP is great, and influenced the design of PyText in several ways. There are some central design decisions of AllenNLP that make it incompatible with PyTorch's jit tracing and so make productionizing models require much more manual work. It also generally leaves preprocessing up to the user, so preprocessing consistently between training and inference is outside the scope of what AllenNLP does.
