floris.tools.power_rose.load() requires class instantiation

I am writing a script to load a PowerRose object from a file I pickled previously using floris.tools.power_rose.PowerRose.save(). The script looks like this:

# General modules
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

# FLORIS-specific modules
import floris.tools as wfct
import floris.tools.power_rose as pr

power_rose = pr.PowerRose(name, df_power, df_turbine_power_no_wake, df_turbine_power_baseline)
power_rose.load(filename = "PowerRose_All.p")

However, as is clear from the last two lines I have to instantiate the PowerRose class in order to load a PowerRose instance from a pickled PowerRose, which seems to me to be a causality problem. The only solution I can think of would be to create a DataFrames of the same size as "PowerRose_All.p" filled with zeros to use in the instatiation.

Yes, you need to instantiate a power_rose object before you can use the load method. However, you do not need to supply DataFrames to do this. This could be accomplished by:

import floris.tools.power_rose as pr

power_rose = pr.PowerRose()
power_rose.load(filename="PowerRose_All.p")
