Dialo G P T large

Introduction

DialoGPT is a state-of-the-art (SOTA) large-scale pretrained dialogue response generation model designed for multiturn conversations. It is capable of generating responses that are comparable to human responses, as demonstrated by its performance in a single-turn conversation Turing test. The model was trained on 147 million multi-turn dialogues from Reddit discussion threads.

Architecture

DialoGPT is based on the Transformer architecture, specifically designed for text generation tasks. It utilizes a large-scale dataset to pretrain the model, thereby enhancing its ability to understand and generate coherent and contextually relevant dialogue responses.

Training

The model was trained by leveraging a vast dataset consisting of 147 million multi-turn dialogues sourced from Reddit. This extensive dataset contributes to the model's ability to simulate human-like conversations effectively. For detailed information on preprocessing and training, refer to the original DialoGPT repository.

Guide: Running Locally

To run DialoGPT locally:

1. Install Transformers and PyTorch: Ensure you have the transformers library and torch installed.

2. Load the Model and Tokenizer:

   from transformers import AutoModelForCausalLM, AutoTokenizer
   import torch
   
   tokenizer = AutoTokenizer.from_pretrained("microsoft/DialoGPT-large")
   model = AutoModelForCausalLM.from_pretrained("microsoft/DialoGPT-large")
   

3. Interact with the Model:

   • Use the following code snippet to engage in a conversation with the model:

     # Let's chat for 5 lines
     for step in range(5):
         new_user_input_ids = tokenizer.encode(input(">> User:") + tokenizer.eos_token, return_tensors='pt')
         bot_input_ids = torch.cat([chat_history_ids, new_user_input_ids], dim=-1) if step > 0 else new_user_input_ids
         chat_history_ids = model.generate(bot_input_ids, max_length=1000, pad_token_id=tokenizer.eos_token_id)
         print("DialoGPT: {}".format(tokenizer.decode(chat_history_ids[:, bot_input_ids.shape[-1]:][0], skip_special_tokens=True)))
     

4. Utilize Cloud GPUs: For efficient processing and to handle larger-scale interactions, consider using cloud GPU services such as AWS, Google Cloud, or Microsoft Azure.
