Error when modifying planting date

[cgalea15]

I'm trying to apply changes in planting and harvesting dates with the following configuration in the model:

"Climate input
lars_fp=get_filepath('SG02_software.dat')
base=pd.read_csv(lars_fp, sep='\t', engine='python')
base['Date']=pd.to_datetime(base['Date'])
Crop input
crop=Crop('BarleyGDD',planting_date='02/01', CalendarType=2)
Soil input
soil=Soil('SandyLoam')
Initial water condition input
init_wc = InitialWaterContent('FC') # default is field capacity. Maybe we can play with this values to adapt it to the actual yield

model=AquaCropModel('2001/01/01','2023/04/30',base,soil,crop,init_wc)
model.run_model(till_termination=True)"

It works if the planting date is 05/x but it returns the following error when changing it:

"File ~\anaconda3\Lib\site-packages\aquacrop\solution\biomass_accumulation.py:104 in biomass_accumulation
dB = WPadj * (Tr / et0)"

I printed et0 and Tr values in this line and most Tr are 0 and some et0 are 0 too. I imagine that it has something to do with the calculation of Tr maaybe because of the climate data but I wanted to share it in case someone could help me.
Thanks

I forgot to include the actual error that python returns

ZeroDivisionError: float division by zero
