Use with transformers
You can run conversational inference using the Transformers Auto classes with the generate() function. Here's an example:
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
model_id = "Writer/palmyra-mini-thinking-a"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.float16,
device_map="auto",
attn_implementation="flash_attention_2",
)
messages = [
{
"role": "user",
"content": "You have a 3-liter jug and a 5-liter jug. How can you measure exactly 4 liters of water?"
}
],
input_ids = tokenizer.apply_chat_template(
messages, tokenize=True, add_generation_prompt=True, return_tensors="pt"
)
gen_conf = {
"max_new_tokens": 256,
"eos_token_id": tokenizer.eos_token_id,
"temperature": 0.3,
"top_p": 0.9,
}
with torch.inference_mode():
output_id = model.generate(input_ids, **gen_conf)
output_text = tokenizer.decode(output_id[0][input_ids.shape[1] :])
print(output_text)
