## Use in Transformers |
|
|
|
Please load the tokenizer with 'add_bos_token = True' parameter as the underlying OpenLLaMa model and this model were trained with a BOS token. |
|
|
|
``` |
|
import os |
|
import torch |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
model_name = 'VMware/open-llama-0.3T-7B-open-instruct-v1.1' |
|
|
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_name, add_bos_token = True) |
|
|
|
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) |
|
|
|
''' |
|
The attention mechanism of a transformer model is designed to help the model understand the relationship between different parts of a sentence. |
|
The model uses a weighted attention score to determine how much each input token contributes to the output. |
|
The attention score is calculated by looking at the similarity between each input token and the output token,and assigning a weight to each input token based on this similarity. |
|
This way, the model can better understand the relationship between different parts of a sentence and generate more accurate predictions. |
|
|
|
''' |
|
``` |
|
|
|
## Drawbacks |
|
|
|
- The model was trained on a partially trained Open-LLaMA checkpoint. (300B tokens). |
|
- The model is inconsistent with outputting '\n' tokens as majority of the dataset is obtained from [mosaicml/dolly_hhrlhf](https://huggingface.co/datasets/mosaicml/dolly_hhrlhf) and that dataset removed newline characters from responses. |
