The output is so bad - total garbage what I am doing wrong? It is also super slow and requires huge amount of RAM

Here my entire command
from transformers import AutoTokenizer, OPTForCausalLM
tokenizer = AutoTokenizer.from_pretrained("facebook/galactica-1.3b")
model = OPTForCausalLM.from_pretrained("facebook/galactica-1.3b", device_map="auto")
input_text = "The benefits of deadlifting\n\n"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to("cuda")
outputs = model.generate(input_ids,new_doc=False,top_p=0.7, max_length=1000)
print(tokenizer.decode(outputs[0]))
And the output is total repetition and garbage. I am trying to generate an article based on the topic sentence I provide
Also even 28 GB VRAM is not enough for 6.7b model. I am testing CPU runtime on IPU and it has been more than 2 hours with just 6.7b model.
the output as below
The benefits of deadlifting
The benefits of deadlifting are numerous. It is a simple, inexpensive, and effective method of reducing the risk of injury to the shoulder and elbow. It is also a simple and effective method of reducing the risk of injury to the hand.

Thanks for reporting, will look into this and get back to you tomorrow
In half precision mode 6.7b fits on a 3090. As for the output quality, you need to tweak generation parameters a little, this blogpost explains quite a bit.
Here's a snippet of how I use it:
import torch, gc
from transformers import AutoTokenizer, OPTForCausalLM
tokenizer = AutoTokenizer.from_pretrained("facebook/galactica-6.7b")
tokenizer.pad_token_id = 1
tokenizer.padding_side = 'left'
tokenizer.model_max_length = 2020
model = OPTForCausalLM.from_pretrained("facebook/galactica-6.7b", device_map="auto", torch_dtype=torch.float16)
input_text = """# Scientific article.
title: Contrastive analysis of models used for DRAM simulation.
# Introduction
"""
input_ids = tokenizer(input_text, return_tensors="pt", padding='max_length').input_ids.to("cuda")
outputs = model.generate(input_ids,
max_new_tokens=1000,
do_sample=True,
temperature=0.7,
top_k=25,
top_p=0.9,
no_repeat_ngram_size=10,
early_stopping=True)
print(tokenizer.decode(outputs[0]).lstrip('<pad>'))
gc.collect()
torch.cuda.empty_cache()
padding='max_length'
means new_doc=True
, set to False

@AbstractQbit ty very much for answer
May I ask something regarding this format
# Scientific article.
title: Contrastive analysis of models used for DRAM simulation.
# Introduction
So the text generator understand # character as a special character and do something?
what does these 2 parameter do?
pad_token_id
padding_side
Authors say in the paper that the model was trained on text in markdown format, so giving markdown-ish prompts to the model should probably work best, I guess.
Padding params I took from here
Lines 85 to 86 in f6d9b0a
@AbstractQbit ty so much for answers
about these hyper parameters, have you tested them or how did you come up with those values?
do_sample=True,
temperature=0.7,
top_k=25,
top_p=0.9,
no_repeat_ngram_size=10,
early_stopping=True
@FurkanGozukara Those are just what I've ended up with after playing around with the model for a bit. There was no real methodology for picking those. They just produced somewhat sensible output, so I've shared them here as a starting point for you. There are no one-size-fits-all parameters, you'll have to experiment yourself to tailor them to your needs.
As to what they do, please refer to the article I've linked above. I'm not an NLP expert, so I can't explain them any better than HF people.
@FurkanGozukara I played around with your prompt, and this is what the model came up with.
Title: The benefits of deadlifting
Abstract: The purpose of this study was to determine the effect of deadlifting on the cardiovascular system.
The study consisted of a group of 13 men and 11 women who were randomly assigned to an experimental group (n = 24) or a control group (n = 24,).
Subjects in the experimental group performed deadlifting exercises 2 days per week for 6 weeks, while subjects in the control group did not participate in any exercise program.
The 6-week program consisted of a 3-week progressive phase and a 3-week maintenance phase.
At the end of each phase, a graded exercise test (GXT) was performed on a treadmill to determine peak oxygen consumption (VO2peak), ventilatory threshold (VT), and heart rate (HR) at the VT.
At the end of the 6-week program, VO2peak increased by 15.4% (P < 0.05) in the experimental group compared with a 0.9% increase (P > 0.05) in the control group.
The experimental group demonstrated a 13.9% increase (P < 0.01) in HR at the VT compared with a 2.4% increase (P > 0...</s>
I followed the parameters from @AbstractQbit.
Here is the complete code. I could run it on one Titan RTX (24GB VRAM) but only when using half precision.

@AbstractQbit your answer has hleped me a lot, many thanks!
Do you (or anyone else) now how to use the new_doc
(padding
) parameter to continue a document generation after the first prompt? Do I have to use the output of the prompt as input to the next one or it's better to use larger max_new_tokens
value?
i'm getting CUDA error with @legor and @AbstractQbit ' code

@legor ty so much. I wonder they release a model without any proper example as yours.
@AbstractQbit your answer has hleped me a lot, many thanks!
Do you (or anyone else) now how to use the
new_doc
(padding
) parameter to continue a document generation after the first prompt? Do I have to use the output of the prompt as input to the next one or it's better to use largermax_new_tokens
value?
unfortunately hugging face doesnt support newdoc i dont know why. your other questions i also wonder
