Chat Bot With PyTorch - NLP And Deep Learning - Python Tutorial (Part 2)

In this Python Tutorial we build a simple chatbot using PyTorch and Deep Learning. I will also provide an introduction to some basic Natural Language Processing (NLP) techniques.

1) Theory + NLP concepts (Stemming, Tokenization, bag of words)
2) Create training data
3) PyTorch model and training
4) Save/load model and implement the chat

Error string indices must be integers at for intent in intents [intents]:
tag=intent ['tag']
What should I do.

hi thanks for the great post, if I train modal locally and host data.pth from local to server(on heroku) will this work? my intents is huge i don't want run long task on server

[rookeGG]

This is a long shot but how hard would it be to add a feature where the chat bot user can turn the bots reply's into text to speech, as technically it pulls the answers from the intents file so not sure if it could when it gives its answer then also read that answer out loud.

[mayankmalkoti]

I lemmatized instead of stemming. How would that effect accuracy or performance?

[bedifferentlearners]

RuntimeError: expected scalar type Long but found Int . please solve this error

[arunkara]

This tutorial is amazing for someone just starting out. Could you please make an intermediate course on using a ChatBot to Automate Website Tasks :) !!!

[waqasqureshi]

Minor correction- At 21:25 it should be self.x_data[index] rather than self.x_data[idx] same for self.y_data
