Can't get return_calculated_values to execute in mplfinance (Python)

I am trying to get the ATR for each of the stocks I am plotting (renko & PNF) but get an error. Following is the code I am using which is basically the same as what I found on Github for "return_calculated_values."

https://github.com/matplotlib/mplfinance/issues/135

ChartATR = 14 ###### atr_length=ChartATR retvals = ()

try:
    ThisChart = 'Charts\\' + ThisStock + '-renko.png'
    ThisChartTitle = '\n ' + ThisStock + ' - renko' + " " + Dayte
    # ====> The next line of code works <====================================================
    mpf.plot(year,type='renko', renko_params=dict(brick_size='atr', atr_length=ChartATR),savefig = ThisChart, title = ThisChartTitle)
    # ====>This next line of code does not work (generates the error <===========================================
    mpf.plot(year,type='renko', renko_params=dict(brick_size='atr', atr_length=ChartATR), return_calculated_values=retvals)
    # print('ATR =',retvals[size]) # This generates an error <==========================
    print('ATR =',retvals)
except:
    print("An error occured processing " + ThisStock)
    print()

I appreciate any help or thoughts.

Thanks, Manny

Problem solved:

retvals = () should be a dictionary: retvals = {}, and needs to be cleared with each pass
