ModuleNotFoundError: No module named 'pyspark.dbutils' - pyspark

Question

I am running pyspark from an Azure Machine Learning notebook. I am trying to move a file using the dbutil module.
from pyspark.sql import SparkSession
spark = SparkSession.builder.getOrCreate()
def get_dbutils(spark):
try:
from pyspark.dbutils import DBUtils
dbutils = DBUtils(spark)
except ImportError:
import IPython
dbutils = IPython.get_ipython().user_ns["dbutils"]
return dbutils
dbutils = get_dbutils(spark)
dbutils.fs.cp("file:source", "dbfs:destination")
I got this error:
ModuleNotFoundError: No module named 'pyspark.dbutils'
Is there a workaround for this?
Here is the error in another Azure Machine Learning notebook:
---------------------------------------------------------------------------

During handling of the above exception, another exception occurred:
