How can I release memory after creating matplotlib figures

Question

I have several matlpotlib functions rolled into some django-celery tasks.

Every time the tasks are called more RAM is dedicated to python. Before too long, python is

Answer 1

import matplotlib.pyplot as plt
from datetime import datetime
import gc

class MyClass:
    def plotmanytimesandsave(self):
        plt.plot([1, 2, 3])
        ro2 = datetime.now()
        f =ro2.second
        name =str(f)+".jpg"
        plt.savefig(name)
        plt.draw()
        plt.clf()
        plt.close("all")


for y in range(1, 10):
    k = MyClass()
    k.plotmanytimesandsave()
    del k
    k = "now our class object is a string"
    print(k)
    del k
    gc.collect

with this program you will save directly as many times you want without the plt.show() command. And the memory consumption will be low.
