jupyterlab/jupyterlab#16139 while i use spyder/Jupyterlab, i found some unintended(i presume) memory leak.
above issue, i try to make list/array inside of python function and return it
but if i try to use the function with one line execution, there happen incresing memory and never decrease
first i think it is problem of spyder/JupyterLab, but same issue occur in IPython Shell in command prompt
i attach code below.
please review
import numpy as np import gc cnt = 100000000 def np_gen(): _ret = np.ones(cnt, dtype = np.int32) try: return _ret finally: while gc.collect(): print("collect gcing...")
execute sequence.
Mem usage of windows task mgr.
case study. if i use %reset, all variable remove.
%reset out => remove output, but memory never recovered
%xdel => can't remove because output data has no variable name

Interesting.
If someone want to investigate, you might want to use https://objgraph.readthedocs.io/en/stable/ and a weakref to the created object to see what is holing to it.
Sorry, something went wrong.
