how to clear jupyter notebook cell code from the memory after execution

Question

A visualizing code consumes 1gb+ of ram memory and notebook gets unresponsive. Is there any solution to remove it from memory without hurting other codes?. Restarting kernel isn't fruitful. Thank you

Answer 1

I had 6GB files for Pandas handling and cleaning. In a loop execution from file folder each next file was processed two times slower than the previous one (43 min, 86, 125, 254 min, etc.). Restarting kernel was not an option. I just added one line for deleting variable (Pandas dataframe in my case) on the bottom of each cell. It solves the day for me!

import pandas as pd

data = pd.read_csv('file_name.csv')

#any amount of lines for your actions

#after the next line memory becomes clean and ready to start with a new cell. The same approach at the end of a loop. 

del data
