How can I release memory after creating matplotlib figures
Did you try to run you task function several times (in a for) to be sure that not your function is leaking no matter of celery?Make sure that django.settings.DEBUG is set False( The connection object holds all queries in memmory when DEBUG=True).
import matplotlib.pyplot as pltfrom datetime import datetimeimport gcclass 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.collectwith this program you will save directly as many times you want without the plt.show() command. And the memory consumption will be low.
