# VMware/open-llama-13B-open-instruct |
|
Instruction-tuned version of the fully trained Open LLama 13B model. The model is open for <b>COMMERCIAL USE</b>. <br> |
|
|
|
<b> NOTE </b> : The model was trained using the Alpaca prompt template |
|
<b> NOTE </b> : Fast tokenizer results in incorrect encoding, set the ```use_fast = False``` parameter, when instantiating the tokenizer |
|
<b> NOTE </b> : The model might struggle with code as the tokenizer merges multiple spaces |
|

## Use in Transformers |
|
|
|
``` |
|
import os |
|
import torch |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
model_name = 'VMware/open-llama-13b-open-instruct' |
|
|
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name, use_fast=False) |
|
|
|
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.float16, device_map='sequential') |
|
|
|
prompt_template = "Below is an instruction that describes a task. Write a response that appropriately completes the request.\n\n### Instruction:\n{instruction}\n\n### Response:" |
|
|
|
prompt = 'Explain in simple terms how the attention mechanism of a transformer model works' |
|
|
|
|
|
inputt = prompt_template.format(instruction= prompt) |
|
input_ids = tokenizer(inputt, return_tensors="pt").input_ids.to("cuda") |
|
|
|
output1 = model.generate(input_ids, max_length=512) |
|
input_length = input_ids.shape[1] |
|
output1 = output1[:, input_length:] |
|
output = tokenizer.decode(output1[0]) |
|
|
|
print(output) |
|
``` |
