Can't run bta-lib inside a thread about bta-lib

[drhighliner]

Take a look at the pull request section. Someone found a solution for this (thread) issue which works quite nicely.

Team, getting same error
any solution ?

I found a workaround which is less than ideal but will have to do until we get an update from the maintainers.

I created a separate script for the bta-lib calculations that had looked something like this...

import pandas as pd
import pickle
import btalib
import sys

symbol = sys.argv[1]

with open('./data/' + symbol + '/' + symbol + '_kline.p', 'rb') as handle:
    kline_df = pickle.load(handle)

sma = btalib.sma(kline_df).df

with open('./data/' + symbol + '/sma.p', 'wb') as handle:
    pickle.dump(sma, handle)

...and then, from the main script, from inside the thread, I run...

subprocess.Popen(['python', 'bta.py', 'BTCEUR']).wait()

with open('./data/' + symbol + '/sma.p', 'rb') as handle:
    sma = pickle.load(handle)

It's clunky but it will have to do for now.

Has anyone found a better explanation why BTA-Lib doesn't work within threading? Getting the same errors with different indicators
