Error message

 objc[30548]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called.
objc[30548]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process.

Steps to Reproduce

import chromadb
import lancedb

from robyn import Response, Robyn, jsonify, Request
from langchain.vectorstores import LanceDB

# from langchain.documents import Document




app = Robyn(__file__)



db = lancedb.connect("./.lancedb_test")
data = [{"vector": [1.1, 1.2], "lat": 45.5, "long": -122.7}, {"vector": [0.2, 1.8], "lat": 40.1, "long":  -74.1}]



@app.get("/")
def home():
    # print("This is the new table", db.open_table("my_table_new") )

    data = [
        {"vector": [3.1, 4.1], "item": "foo", "price": 10.0},
        {"vector": [5.9, 26.5], "item": "bar", "price": 20.0},
    ]

# Synchronous client
    tbl = db.open_table("my_table2")

Hi from LanceDB. We unfortunately don't support multiprocessing with fork(). If possible, you should use spawn instead. More detail here: lancedb/lance#2204 (comment)

Hey @wjones127 👋

Thanks for letting me know. Unfortunately, robyn doesn't work properly with spawn instead of fork. Let me try and address that
