How to use this model

To use this model:

python

import transformers
import pyreft

device = "cuda"

model_name_or_path = "meta-llama/Meta-Llama-3-8B"
model = transformers.AutoModelForCausalLM.from_pretrained(

)

# Load the ReFT model
reft_model = pyreft.ReftModel.load(
    "./CiscoDevNetSandboxRunningConfig", model
)

# Ensure the ReFT model components are also on the GPU

# Define the prompt template
prompt_no_input_template = """<s>[INST] <<SYS>>
You are a computer networking expert specialized in Cisco IOS XE running configurations.
<</SYS>>

%s [/INST]

# Load the tokenizer
