'''
配置psutil    $sudo pip install psutil

print(ghi.getHardwareInfo('/', '/home/room304/lichengyuan/make_voc2007.py').disk_used) 
第一个参数为硬盘编号，可以通过psutil.disk_partitions()获得
第二个参数为需要监测大小的文件路径

s = ghi.getHardwareInfo('/', '/home/room304/lichengyuan/make_voc2007.py')
所有参数单位为M
s.disk_total 硬盘大小
s.disk_used 已使用硬盘大小
s.disk_free 未使用硬盘大小
s.disk_percent 硬盘使用率
s.ram_total 内存大小
s.ram_used 已使用内存大小
s.ram_available 可以使用的内存大小
s.ram_percent 内存使用率
s.cpu_percent cpu使用率
s.temperatures 硬件温度，结构体
s.file_size 监测的文件大小
