Description

Megatron is a large, powerful transformer developed by the Applied Deep Learning Research team at NVIDIA. This particular Megatron model was trained from a generative, left-to-right transformer in the style of GPT-2. This model was trained on text sourced from Wikipedia, RealNews, OpenWebText, and CC-Stories. It contains 345 million parameters.

How to run Megatron GPT2 using Transformers

Text generation

The following code shows how to use the Megatron GPT2 checkpoint and Transformers to generate text.

import os
import torch

from transformers import GPT2Tokenizer, GPT2LMHeadModel

tokenizer = GPT2Tokenizer.from_pretrained("gpt2")
model = GPT2LMHeadModel.from_pretrained("robowaifudev/megatron-gpt2-345m")

if torch.cuda.is_available():
    device = torch.device("cuda")
    model.half()
else:
    device = torch.device("cpu")
model.to(device)
model.eval()

# Generate
prompt = (
"It was a bright cold day in April, and the clocks were striking thirteen. Winston Smith,"
)
input_ids = tokenizer.encode(prompt, return_tensors="pt").to(device)
output = model.generate(
    input_ids=input_ids,
    max_length=len(input_ids) + 128,
    do_sample=True,
    top_k=64,
    top_p=0.9,
    temperature=0.8,
    num_return_sequences=2,
    repetition_penalty=1.025
)

# Output the text
print("Prompt:", prompt)
print("*" * 3)
for i, sentence in enumerate(output):
    text = tokenizer.decode(sentence, clean_up_tokenization_spaces=True)
    print(f"{i}:", text)
    print("*" * 3)
