Получение ([Errno -2] Имя или служба неизвестны)))) — при подключении к хранилищу SQL Databricks из записной книжки Azur ⇐ Python

[Anonymous]

Я пытаюсь извлечь данные из хранилища SQL Databricks через блокнот машинного обучения Azure с помощью Databricks-SQL-Connector и получаю следующую ошибку в блокноте Jupyter. Я использую следующий скрипт:
from databricks import sql
import os

connection = sql.connect(
server_hostname = "adb-4285847157798999.17.azuredatabricks.net",
http_path = "/sql/1.0/warehouses/37667bb8d1fe23fa",
access_token = "")

cursor = connection.cursor()

cursor.execute("SELECT * from range(10)")
print(cursor.fetchall())

cursor.close()
connection.close()

Ниже приведена ошибка, которую я получаю. Пожалуйста, предложите, как решить эту проблему, поскольку я новичок в этом.
