python
import os
os.environ["OPENAI_API_KEY"] = "your_openai_api_key_here"

I'm using the code above to set my openai API key, when trying the Paul graham example, but I keep getting an authentication error.

Is there a better place to set the API key then in the file im running?

for tests purposes you can set on the terminal as well

export OPENAI_API_KEY=key

or python-dotenv

Ok thanks I'll use the dotenv and set the key in a file

EEmanuel Ferreira

let me know if it works 🙂

nnimnems

Hmm now it's saying it can't find the API key and to set it. I've tried putting the .env file in the root of the project, in the llama index folder and in the examples and Paul graham folder, still nothing,🙃

nnimnems

Can I set it as a param next to the query ?

EEmanuel Ferreira

I would recommend you to try this way first

EEmanuel Ferreira

because you can check if your api key is working first

EEmanuel Ferreira

authentication error happens usually when it's expired, deactivated or wrong

nnimnems

Hmm ok will try, but I just created it

nnimnems

Yeah it worked via terminal

from llama_index import VectorStoreIndex, SimpleDirectoryReader, ServiceContext, LLMPredictor
from langchain.llms import OpenAI

documents = SimpleDirectoryReader('data').load_data()

service_context = ServiceContext.from_defaults(
    llm_predictor=LLMPredictor(llm=OpenAI(model_name='text-davinci-003', temperature=0, openai_api_key='apiKey'))
)

index = VectorStoreIndex.from_documents(documents, service_context=service_context)

query_engine = index.as_query_engine()
response = query_engine.query("What did the author do growing up?")
print(response)

Must be my environment setup

EEmanuel Ferreira

In this way you can use as a parameter as well

EEmanuel Ferreira

yea probably, did you create a virtual environment?

nnimnems

No, i was lazy,😞

EEmanuel Ferreira

I'm a JS man, not used to it tbh haha

EEmanuel Ferreira

so probably can be it

nnimnems

I was really excited when I found Llama Index so I just wanted to jump in

nnimnems

I'll set it up properly though

nnimnems

Thank you for your help!

@nimnems did you ever figure this out? I've never had issues with it before but for some reason my normal index setup isn't working. Getting the no api key error. Can't figure out why.

nnimnems

I haven't figured out why the .env in my project folder is not being read. However, it did work when I set it from terminal as described above. On my windows machine I had to search for the equivalent CMD prompt which is SET OPENAI_API_KEY=key

nnimnems

I'm chalking it up to a path issue with Python, and I guess yet again I'm reminded that using a virtual environment is best.

mmatt_a

Hmm interesting. I'm running into the issue in a Google Colab notebook. I'll post when I figure it out
