Reproduction

from langchain.llms import OpenAI llm = OpenAI(openai_api_key=INSERT_API_KEY, temperature=0.9) llm.predict("What would be a good company name for a company that makes colorful socks?")

Expected behavior

I was following the langchain quickstart guide, expected to see something similar to the output.

Langchain Version: 0.0.74 is 6 months old. Upgrading should fix this. Run pip install langchain --upgrade

[ArunD]

Run pip install langchain --upgrade

These doesn't fix the issue

[ArunD]

import os
api_key = os.environ.get('OPENAI_API_KEY')
from langchain.llms import OpenAI

llm = OpenAI(openai_api_key=api_key,model_name="text-davinci-003",temperature=0.9)
x = llm(prompt='"What would be a good company name for a company that makes colorful socks?"')

print(x)

[NityaSG]

pip install langchain --upgrade --user try this

[stonez56]

Do not use llm.predict Just use ArunD's solution and it worked. x = llm(prompt='xxx')

[NityaSG]

Do not use llm.predict Just use ArunD's solution and it worked. x = llm(prompt='xxx')

LLM.predict is recommended by official langchain document in the latest version

[vishalchandra]

pip install langchain --upgrade --user

This worked.

[wangwei1237]

pip install langchain --upgrade --user

This worked.

Upgrade the langchain version to the latest version(0.0.272), the same problem is fixed!

Those experiencing issues have likely installed Langchain in an environment alongside other Python libraries, leading to compatibility problems. My recommendation is to start fresh. According to its documentation, Langchain comes bundled with all the necessary libraries and requires Python version 3.8.1 or higher, but lower than 4.0. Therefore, create a new environment with a compatible Python version, and then only install Langchain using pip. You can add other required libraries afterward and remove if again issues arise
