databricks with python can't use fs module AttributeError: module 'dbutils' has no attribute 'fs'

Question

I am using azure databricks for the first time to read some files and trying to use python with dbutils.fs.ls("/mnt")

But I get an error saying that dbutils doesn't have fs module. I was reading and say that all databricks come with dbutils already.

AttributeError: module 'dbutils' has no attribute 'fs'

if i do

print(dir(dbutils))

['Console', 'DBUtils', 'FileInfo', 'Iterable', 'ListConverter', 'MapConverter', 'MountInfo', 'NotebookExit', 'Py4JJavaError', 'SecretMetadata', 'SecretScope', 'WidgetsHandlerImpl', 'builtins', 'cached', 'doc', 'file', 'loader', 'name', 'package', 'spec', 'absolute_import', 'makeTensorboardManager', 'namedtuple', 'print_function', 'range', 'stderr', 'stdout', 'string_types', 'sys', 'zip']

i found that it suppose to have the library already install https://docs.databricks.com/user-guide/dev-tools/dbutils.html#dbutils

Is there a magic trick? I wanted to check if I have a file is mounted if not mount it and unmount it.

You will get this error "AttributeError: module 'dbutils' has no attribute 'fs'" if you import dbutils in your notebook. There is no need to do this import as the dbutils are available in the notebook on startup. print(dir(dbutils)) should return

['CredentialsHandler', 'FSHandler', 'LibraryHandler', 'NotebookHandler', 'PreviewHandler', 'SecretsHandler', 'call', 'class', 'delattr', 'dict', 'dir', 'doc', 'eq', 'format', 'ge', 'getattr', 'getattribute', 'getstate', 'gt', 'hash', 'init', 'init_subclass', 'le', 'lt', 'module', 'ne', 'new', 'reduce', 'reduce_ex', 'repr', 'setattr', 'sizeof', 'str', 'subclasshook', 'weakref', 'entry_point', 'help', 'shell', 'widgets']

You don't need to restart the cluster, you can 'Clear State' from the clear tab in your workspace, or you can 'import pyspark.dbutils'.
