TypeError: reduce() of empty sequence with no initial value

[OtenMoten]

Hello community,

if you got this error TypeError: reduce() of empty sequence with no initial value

Here is the workaround:

1. Go to your custom hyperopt file, in this case BBRSIOPT.py

2. Change

   dataframe.loc[
   reduce(lambda x, y: x & y, conditions),
   'buy'] = 1

   in

   if conditions:
   dataframe.loc[
       reduce(lambda x, y: x & y, conditions),
       'buy'] = 1

It should work now.
