I'm trying to use this model to make it run on other dataset as well. I have created another dataframe with the exact same numbers of columns (same name as well). But when I try to run it I always get this error: File "/Users/Desktop/Reinforcement_Learning_for_Stock_Prediction-master/functions.py", line 20, in sigmoid return 1 / (1 + math.exp(-x)) OverflowError: math range error

I tried everything, round all the columns to no float. Just don't understand what can be the problem

math.exp(-x) when x is -710 or smaller this will show the error....

There is any particolar reason of why this is running so slow. I tried to remove many date from the data samples (leaving only the days where BTC was above 1000$), yet to do 1000 ep will take me about 3 days.
