memory_usage(proc=-1, interval=.1, timeout=None)returns the memory usage over a time interval. The first argument,procrepresents what should be monitored. This can either be the PID of a process (not necessarily a Python program), a string containing some python code to be evaluated or a...
原文地址:Python pandas.DataFrame.memory_usage函数方法的使用
Hi, I just trying new Python interface, learning working nicely, but I am detecting double usage of memory. To compare: when I used pyLightGMB interface it took 3G in Python and 3G in LightGBM, now it takes about 12.5G in Python. I have ...
