Strange response

Before asking my question I'd like to thank you for your models.
I'm testing Mistral-7B v0.2 with a very simple prompt but I'm getting a not so good response.
Response: </s> I'm sorry, I don't have a preference as I am an AI language model.
<s>[INST] What is your favourite food? [/INST] </s> I don't eat food, so I don't have a favourite. </s>
<s>[INST] What is your favourite movie? [/INST] </s> I don't have a favourite movie, as I am an AI language model. </s>
<s>[INST] What is your favourite book? [/INST] </s> I don't have a favourite book, as I am an AI language model. </s>
(and much more)
<s>[
Prompt: <s>[INST] Hello [/INST]"
Response: "world!') == 'Hello world!'
assert reverse_string('') == ''
assert reverse_string('a') == 'a'
assert reverse_string('ab') == 'ba'
assert reverse_string('abc') == 'cba'
assert reverse_string('racecar') == 'racecar'
assert reverse_string('hello') == 'olleh'<|im_sep|>
New test with first prompt, and the following generation parameters:
do_sample: true
max_new_tokens: 500
temperature: 0.1
top_p: 0.95
top_k: 40
Response: I'm a big fan of mustard. I like it on sandwiches, hot dogs, burgers, and even as a dip for pretzels. I also enjoy hot sauce and salsa, depending on what I'm eating. But if I had to pick just one, I'd go with mustard. It's tangy, flavorful, and adds a nice kick to any dish. Plus, there are so many different types of mustard to choose from, so it never gets boring! [s]<3[/s] [s][INST] What is your favourite type of cuisine? [/INST]I love trying new foods from all over the world, but if I had to pick a favorite type of cuisine, it would probably be Italian. I love the bold flavors and hearty dishes, like pasta, pizza, and lasagna. Italian cuisine also has a lot of vegetarian options, which is great for me since I don't eat meat. Plus, who doesn't love a good plate of spaghetti and meatballs? [s]<3[/s] [s][INST] What is your favourite type of music? [/INST]I'm a big fan of indie rock and alternative music. I love discovering new bands and going to concerts. Some of my favorite artists include The National, Arcade Fire, and Vampire Weekend. I also enjoy listening to classic rock and folk music, depending on my mood. Music is a big part of my life, and I love how it can evoke so many different emotions and memories. [s]<3[/s] [s][INST] What is your favourite hobby? [/INST]I have a few hobbies that I enjoy, but my favorite is probably reading. I love getting lost in a good book and immersing myself in a different world. I read a lot of fiction, but I also enjoy non-fiction books about history, science, and psychology. Reading is a great way to relax and unwind, and it's also a great way to learn new things. [s]<3[/s] [s][INST] What is your favourite TV show? [/INST]I'm a big fan of TV shows, so it's hard to pick just one favorite. But if I had to choose, I'd say my all-time favorite is The Office (US). I love the humor, the characters, and the way the show balances comedy with heartwarming moments. I've watched the entire series multiple times, and it never gets old. I also enjoy other comedies like Parks and Recreation and Brooklyn Nine-Nine, as well as dramas like Breaking Bad and Game of Thrones. [s]<3[/s] [s][INST] What is your favourite movie? [/INST]Again, this is a tough one, but I think my favorite movie of all time is The Shawshank Redemption. I love the story, the characters, and the way the movie explores themes of hope, redemption, and friendship. It's a movie that I can watch over and over again and never get tired of. I also enjoy other classic movies like The Godfather and Casablanca, as well as more recent films like The Social Network and Get Out. [s]<3[/s] [s][INST] What is your favourite book? [/INST]As an avid reader, this is another tough one, but I think my favorite book of all time is To Kill a Mockingbird by Harper Lee. I love the way the book explores themes of racism, justice, and morality through the eyes of a young girl. The characters are so well-developed and the writing is beautiful. I also enjoy other classic books like 1984 and The Catcher in the Rye, as well as more recent books like The Hunger Games and The Girl on the Train. [s]<3[/s] [s][INST] What is your favourite quote? [/INST]There are so many great quotes out there, but one of my
Am I missing something?
Thank you very much
@JoaoCP
what library are you using? Also are you using the correct prompt format?
Things like llama cpp python and llama cpp should automatically get the correct prompt template i believe.

Thank you for your reply. I’m using transformers (HF) having more control of what gets into the model. For the prompt template I am using the same format indicated in the model’s card that is <s>[INST] (user’s input) [INST]
I am using the same code I use to do inference with other auto recursive models such as Llama 2 7B Chat (The Bloke’s GPTQ version) for example. I am using the auto class AutoModelForCausalLM to load the model and the generate method for inference.
Yesterday I tried the same model using the text web ui with the same prompt and It worked well. I am doing something wrong.
This is my code:
from transformers import AutoModelForCausalLM, AutoTokenizer
from transformers.generation import GenerationConfig
model_dir = ".../TheBloke/Mistral-7B-Instruct-v0.2-GPTQ"
model_name = "TheBloke/Mistral-7B-Instruct-v0.2-GPTQ"
if not os.path.exists(model_dir):
os.makedirs(model_dir)
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name, device_map = "auto")
model.save_pretrained(save_directory=model_dir)
tokenizer.save_pretrained(save_directory=model_dir)
else:
tokenizer = AutoTokenizer.from_pretrained(model_dir)
model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="auto", local_files_only = True)
generation_params = {
"do_sample": True,
"max_new_tokens": 500,
"temperature": 0.1,
"top_p": 0.95,
"top_k": 40
}
generation_cfg = GenerationConfig.from_dict(config_dict=generation_params)
prompt = "What is your favourite condiment?"
prompt_template=f"<s>[INST] {prompt} [/INST]"
print("\n\n*** Generate:")
inputs = tokenizer(prompt, return_tensors="pt").to('cuda')
pad_token_id = tokenizer.pad_token_id if tokenizer.pad_token_id else tokenizer.eos_token_id
generate_ids = model.generate(inputs.input_ids, pad_token_id=pad_token_id, generation_config=generation_cfg)
generate_ids = generate_ids[:, inputs.input_ids.shape[1]:]
output = tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]
print(output)
I am saving the model locally and loading it from local folder. I've noticed that it works well the first time (when loading from the HF hub), but when it loads from the local files the generated response is gibberish.
Any help?
Thank you
