AttributeError: 'function' object has no attribute 'orderbook'

I am unable to get the orderbook. Can someone help me with the error? Thanks
Is orderbook function supported?

Error: AttributeError: 'function' object has no attribute 'orderbook'

From empyrial import empyrial, Engine , get_report

portfolio = Engine(
start_date= "2018-01-01", #start date for the backtesting
#end_date= "2023-05-07", #end date for the backtesting

# max_vol = 0.25, #maximize the return for this level of volatility (25%)
#min_weights = 0.01, #invest at least 5% of the capital in every assets
#max_weights = 0.95, #don't invest more than 35% in one asset
#rebalance = ["2018-04-30", "2019-04-30", "2020-04-30", "2021-04-30","2022-04-30","2023-04-30"]
rebalance = "1y" #rebalance every year
)
empyrial.orderbook
get_report(portfolio)

Hey, that's because of two things:

1. get_report doesn't generate an orderbook but empyrial(portfolio) does.
2. You should call empyrial.orderbook after calling the function empyrial.
