import btalib
import pandas as pd

df = pd.read_csv('2006-day-001.txt', parse_dates=True, index_col='Date')
sma = btalib.sma(df)

gives AttributeError: module 'btalib' has no attribute 'sma'

SMMA Function is working good when calling in not threading modus however when code is running in muli thread we get the following error:

Im trying to use bta-lib to calculate rsi indicator although it was fine with the sma function but through an error on rsi function ''' df=pd.read_csv('prices.csv') sma=btalib.sma(df,period=9)#works fine rsi=btalib.rsi(df,period=14)#through an error ''' error= ValueError: cannot set using a slice indexer with a different length than the value... my df len is enough.

BTA-LIB is running into compatibility issues with Numpy. From backtrader forum: bta-lib adx() error

@run-out I found the library version incompatibility! I was running with numpy v1.20.1, the latest version. I installed an older version, the version of numpy available right around when btalib v1.0.0 was released, numpy v1.18.2. It worked 🙌🏼 So that means bta-lib needs to be updated to work with the latest versions of pandas and numpy. Thanks again for taking the time to work this out with me 👍🏼🌷 Here's my output now:
