Ram memory not freed after executing python script on ubuntu system

enter image description hereI am having a Ubuntu system which has 125 Gb of RAM. I executed few python scripts on that system. Those scripts uses numpy arrays and pandas. Now execution was over but still 50 gb of RAM and 2 Gb cache and 8.4 Gb of swap is occupied. At this moment nothing is running on the system. I have googled it. Most of th result shows that python garbage collector is poor in performance. I want this memory to be cleaned and re claim. One of the easiest way is to restart the system but i dont want to restart i want a way to do this when the system is up and running. Kindly tell me how to do this. Thanks

If the process ended then the memory should be freed, you can check what process is using memory by running utility such as htop.

when I have memory issues with python I often do following

del memory_heavy_object_which_is_no_longer_needed

import gc
gc.collect()
