PyText is a research to production platform that Facebook has leveraged to quickly develop state-of-the-art NLP systems and deploy them to critical production use cases. Stef Nelson-Lindall explores several challenges with developing, training, and deploying real production systems with Torch and how to deal with them in NLP use cases. He outlines replicability of pretraining and training, training speed, and resiliency of models once they’ve been successfully trained. You’ll learn about some of the developer efficiency problems with PyText and how the company is addressing them.
