i've defined env variables with openai and pinecone. when I run the following command receive an error

python chatbot.py

I'm using python version 3.11.3. Maybe there is a compatibility issue... * chromadb currently does not support Python 3.11 because of pytorch https://docs.trychroma.com/getting-started

I realized y|n is case sensitive...

Do you want to use Pinecone? (Y/N): N Not using Pinecone or empty Pinecone API key provided. Using Chroma instead Do you want to ingest? (Y/N): Y Using embedded DuckDB with persistence: data will be stored in: ./vectorstore Finished Ingesting, stored at ./vectorstore Using embedded DuckDB with persistence: data will be stored in: ./vectorstore Please enter your question (or type 'exit' to end): what is bitcoin used for? AI: Bitcoin is a digital currency that can be used for various purposes such as online purchases, money transfers, and investments. It is decentralized, meaning that it is not controlled by any central authority or financial institu tion. Instead, it works on a peer-to-peer network, allowing individuals to transact directly with each other without the need for a middleman. Additionally, Bitcoin can be used for international transactions as it is not tied to any specific country or currency. Furthermore, some merchants accept Bitcoin as payment for goods and services.

I had to import for following to ingest.py...

from langchain.document_loaders import DirectoryLoader, PyMuPDFLoader
from langchain.text_splitter import RecursiveCharacterTextSplitter
from langchain.embeddings.openai import OpenAIEmbeddings
from langchain.vectorstores import Chroma

In choosing the methods to use it is case sensitive. You need to use a capital Y for yes and capital N for no
