Error when importing prompts

[florin103]

hi there,
has anyone had this error lately ?
ValueError: 'not' is not a valid parameter name

it errors out even if only these lines in my py file:

import os
import subprocess
from langchain.prompts import ChatPromptTemplate

it throws error at line 3
(btw, quite new to python so bare with me please)

Sounds like it could be a bad installation. If you installed with pip, you might try a forced reinstall:

pip install --upgrade --force-reinstall langchain
