HPR3953: Large language models and AI don't have any common sense
Hobson and Greg are working with volunteers to develop an open source
AI that we call Qary (QA for question answering). We're adding plugins
to support open source large language models (LLMs) like GPT-2 and
Llama2. Here's how you can use LLMs in your own Python Programs.
Create a Hugging Face account:
huggingface.co/join
Create and copy your access token:
Your user
profile
Create a .env file with your access token string:
echo "HUGGINGFACE_ACCESS_TOKEN=hf_..." >> .env
Load the .env variables in your python script using
dotenv package and os.environ:
TIP: Use os.environ to retrieve the dict of variable
values rather than dotenv.load_values- Otherwise other
environment variables that have been set by other shell scripts such as
.bashrc will be ignored.
This confused us when we were getting our GitLab CI-CD pipeline
working and deploying to Render.com.
Each of your cloud services will have different approaches to
setting environment variables.
This token string can be passed as a keyword argument to most of the
pipeline and model classes.
import dotenv
dotenv.load_dotenv()
import os
env = dict(os.environ)
token = env['HUGGINGFACE_ACCESS_TOKEN']
Find the path and name for the model on Hugging Face hub you want to
use:
search for "llama2" in the top search bar on huggingface.co/
TIP: don't hit enter at the end of your search, instead click on
"See 3958 model results for llama2"
I clicked on meta-llama/Llama-2-7b-chat-hf
to see the documentation
On the documentation page for your model you may have to apply for a
license if it's not really open source but business source like Meta
does with its AI so you can't use their models to compete with them
Apply for a license to use Llama2 on ai.meta.com
using the same e-mail you used for your Hugging Face account.
Follow the instructions on
huggingface.co to authenticate your python session
TIP: You'll need to use the kwarg use_auth_token in the
AutoModel.from_pretrained or pipeline
functions.
And it should be set to the token from your Hugging Face profile
page. The hugging face documentation says to use the token
kwarg, but that never worked for me.
from transformers import pipeline, set_seed
generator = pipeline('text-generation', model='openai-gpt')
q = "2+2="
responses = generator(
q,
max_length=10,
num_return_sequences=10
)
responses
[{'generated_text': '2+2= 2.2, 1.1 and'},
{'generated_text': '2+2= 3336 miles. they'},
{'generated_text': '2+2= 2, = 2 = 2'},
{'generated_text': '2+2= 4 = 2 = 5 n'},
{'generated_text': '2+2= 0 ( 1 ) = ='},
{'generated_text': '2+2= 6 times the speed of sound'},
{'generated_text': '2+2= 2 times 5, 865'},
{'generated_text': '2+2= 3 / 7 / 11 ='},
{'generated_text': '2+2= 2 2 n 2 of 2'},
