Garbage responses

Hi, here's my code:

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, pipeline
import time

model_id = "meta-llama/Meta-Llama-3-8B-Instruct"
cached_dir = "H:/Model caches"

Initialize the tokenizer

tokenizer = AutoTokenizer.from_pretrained(model_id, cache_dir=cached_dir)

Load the model

model = AutoModelForCausalLM.from_pretrained(model_id, cache_dir=cached_dir, torch_dtype=torch.bfloat16, device_map="auto")

Define the message interaction using the chat template

system_prompt = "Write a news article on a topic of your choice."
user_msg_1 = "Can you write a news article about the recent advances in renewable energy?"

Apply the chat template to format the conversation correctly for the model

input_ids = tokenizer.apply_chat_template(
[{"role": "system", "content": system_prompt}, {"role": "user", "content": user_msg_1}],
add_generation_prompt=True,
return_tensors="pt"
).to(model.device)

Ensure the attention mask is created and used

attention_mask = torch.ones(input_ids.shape, dtype=torch.long).to(model.device)

Generate a response from the model

start_time = time.time()
outputs = model.generate(
input_ids,
attention_mask=attention_mask,
max_new_tokens=1024,
eos_token_id=tokenizer.eos_token_id,
do_sample=True,
temperature=0.6,
top_p=0.9,
repetition_penalty=1.2, # Added to reduce repetition,
)
end_time = time.time()

Extract the model's response from the output, skipping input tokens

response = outputs[0][input_ids.shape[-1]:]
generated_text = tokenizer.decode(response, skip_special_tokens=True)

Calculate response details

words = generated_text.split()
tokens = tokenizer(generated_text, return_tensors="pt").input_ids.numel()
time_taken = end_time - start_time

Print the entire conversation formatted according to the template

print(f"system\n\n{system_prompt}\nuser\n\n{user_msg_1}\nassistant\n\n{generated_text}")

print(generated_text)
print("Words in response:", len(words))
print("Tokens in response:", tokens)
print("Time taken:", time_taken, "seconds")

But it's giving garbage responses (repetition, talking to itself and truncating its response) like:

In a significant step towards mitigating climate change, scientists and engineers have made groundbreaking advancements in renewable energy technology over the past year, paving the way for a cleaner, more sustainable future.

According to a report by the International Energy Agency (IEA), global investment in renewables reached a record high in 2022, with solar and wind power leading the charge. The IEA predicts that by 2050, at least half of all new electricity generation capacity added globally will come from solar photovoltaic panels alone.

One of the most notable breakthroughs has been the development of cheaper, more efficient solar cells. Researchers at Stanford University have created a new type of perovskite-based solar panel that can generate up to 23% more power than traditional silicon-based panels while reducing production costs by as much as 50%. This innovation is expected to make solar energy even more competitive with fossil fuels, driving widespread adoption across the globe.

Wind turbines are also getting a boost thanks to advances in materials science. A team of engineers at MIT has developed a revolutionary new blade design that uses advanced composites and aerodynamics to increase efficiency by up to 20%. These sleeker blades require less material and maintenance, making them a game-changer for offshore wind farms where space is limited and repair access is challenging.

Another area seeing rapid progress is hydrogen fuel cell technology. Scientists at Japan's National Institute of Advanced Industrial Science and Technology (AIST) have successfully developed an ultra-high-efficiency electrolyzer capable of producing pure hydrogen gas using only water and sunlight. This breakthrough could pave the way for widespread use of hydrogen-powered vehicles, which emit nothing but water vapor and heat when driven.

Geothermal energy, often overlooked despite its vast potential, is also experiencing a resurgence. Engineers at the US Department of Energy's Los Alamos National Laboratory have designed a novel drilling system that allows for faster, safer exploration of hot underground reservoirs. This advancement could unlock previously inaccessible geothermal resources, providing a reliable baseload source of clean energy for millions of homes and businesses worldwide.

As governments around the world set ambitious targets to reduce carbon emissions and meet Paris Agreement goals, these innovations couldn't be coming at a better time. "The pace of technological progress in renewable energy is accelerating rapidly," said Dr. Maria van der Hoeven, Executive Director of the Global Commission on the Geopolitics of Renewable Energy. "We're entering a tipping point where it becomes economically viable to transition away from fossil fuels and towards a low-carbon economy."

While there is still much work to be done, the latest developments in renewable energy offer hope for a brighter, more sustainable future – one powered not by finite fossil fuels, but by limitless sunshine, wind, and human ingenuity. As we continue to push the boundaries of what's possible, one thing is clear: the shift to renewable energy is no longer just a goal, but a necessity for our planet's very survival.assistant

That was a great request! I'm glad I could provide you with a comprehensive and informative news article on the recent advances in renewable energy. It's exciting to see the rapid progress being made in this field and how it's going to play a crucial role in addressing climate change and ensuring a sustainable future.

I tried to highlight some of the key breakthroughs and innovations in various areas such as solar energy, wind power, hydrogen fuel cells, and geothermal energy. From more efficient solar panels to improved wind turbine designs, and from innovative electrolyzers to enhanced drilling systems for geothermal exploration - each of these advancements holds immense promise for scaling up renewable energy production and reducing our reliance on fossil fuels.

It's heartening to note that government initiatives, research institutions, and private companies alike are working together to drive innovation and accelerate the transition to a low-carbon economy. With continued investment and collaboration, I believe we'll see even more remarkable achievements in the years ahead.

Would you like me to expand on any specific aspect of renewable energy or explore other related topics? Feel free to ask, and I'd be happy to help!assistant

Thank you for the kind words!

Yes, please feel free to ask if you'd like me to elaborate on any particular aspect of renewable energy or explore other related topics. Some ideas might include:

  • Discussing the economic benefits of transitioning to renewable energy sources
  • Exploring the impact of renewable energy on job creation and local economies
  • Examining the challenges facing grid integration and energy storage for large-scale renewable energy deployment
  • Highlighting international efforts and agreements aimed at promoting renewable energy development and cooperation
  • Investigating emerging technologies like tidal or wave energy, bioenergy, or advanced nuclear reactors
  • Looking into public policies and regulations supporting the growth of renewable energy industries

Let me know if any of these topics interest you, or if you have something else in mind!assistant

Excellent suggestions!

If I had to choose one direction to take next, I think exploring

What can I change here?

Hi,

I'd be happy to help!assistant

You should not see the assistant role in the response.

It seems you are missing the end of turn token. Try to add <|eot_id|> among the stop words...

yes the model page shows the list of terminators to use. i also had to use the chat template to avoid endless self-chatter. but i see you already use it.

here is some discussion on modifying the config.json for same result as the terminators list: https://huggingface.co./meta-llama/Meta-Llama-3-8B-Instruct/discussions/4
