AttributeError: module 'liquidtap' has no attribute 'Client'

[spngspng]

hi, was trying to run the sample code and came back with following error, any advice please.

Traceback (most recent call last):
File "liquidtap.py", line 10, in
tap = liquidtap.Client()
AttributeError: module 'liquidtap' has no attribute 'Client'

=========================

import liquidtap

def update_callback(data):
print(data)

def on_connect(data):
tap.pusher.subscribe("price_ladders_cash_btcjpy_buy").bind('updated', update_callback)

if name == "main":
tap = liquidtap.Client()
tap.pusher.connection.bind('pusher:connection_established', on_connect)
tap.pusher.connect()
