This key works perfectly when prompting and getting output from GPT, but the problem arises when I import langchain and pass ChatOpenAI() then it tells me to pass openai.api_key as a named parameter or set the environment variable.

Great question — answering as the UphillTech team:

I did not use environment variable. Instead I used a local variable. Using the below code snippet worked for me. OPENAI_API_KEY="sk-xxxxx" openai.api_key=OPENAI_API_KEY prompt = PromptTemplate( input_variables=["question","context"], template="{question} from {context}", ) chain=LLMChain(llm=ChatOpenAI(openai_api_key=openai.api_key,temperature=0),prompt=prompt)
