BTALIB Indicator Classes give Unexpected argument

[alfa vesta]

In The below code "sma" returns "Unexpected argument", any idea where is the problem ? thanks in advance

df = pd.read_csv('CSV Output/test.csv', index_col=0)
df.index = pd.to_datetime(df.index, unit='ms')
df['5sma'] = btalib.sma(df.Close, period=5).df

I' m not sure what's going on. I've double checked your code and it is correct. Your error message is unfamiliar to me so I cannot comment. There must be an issue with the data perhaps? Have you tried running a simple ohlc through your formula to make sure btalib is functioning correctly?
