I want to use multiprocessing for a 'For loop'. So basically from a another dataframe I am passing ID,PID to main dataframe, so depends on ID,PID it will filter the dataframe & build a model. I tried, but it taking same time.
Code:
from time import time
import defs
import multiprocessing
if __name__ == '__main__':
currtime = time()
test =
for index,row in temp_sub.iterrows():
local_id = row["ID"]
local_pid = row["PID"]
p = multiprocessing.Pool(multiprocessing.cpu_count())
df = p.apply(defs.framing_df,(df,local_id,local_pid))
test.append(df)
print ('parallel: time elapsed:', time() - currtime)
#temp_sub : small dataframe consists of ids & pids
#df: main dataframe
#defs: wrote a framing_df function & saved in defs.py file
Where I am making mistake, please let me know. It is working fine, but taking same time as sequential process.
