python查看显卡gpu信息

sudo pip install nvidia-ml-py

import pynvml
pynvml.nvmlInit()
# 这里的1是GPU id
handle = pynvml.nvmlDeviceGetHandleByIndex(1)
meminfo = pynvml.nvmlDeviceGetMemoryInfo(handle)
print(meminfo.total) #第二块显卡总的显存大小
print(meminfo.used)#这里是字节bytes，所以要想得到以兆M为单位就需要除以1024**2
print(meminfo.free) #第二块显卡剩余显存大小

>>> from pynvml import *
>>> nvmlInit()
>>> print "Driver Version:", nvmlSystemGetDriverVersion()#显卡驱动版本
Driver Version: 304.00
>>> deviceCount = nvmlDeviceGetCount()#几块显卡
>>> for i in range(deviceCount):
...     handle = nvmlDeviceGetHandleByIndex(i)
...     print "Device", i, ":", nvmlDeviceGetName(handle) #具体是什么显卡
...
Device 0 : Tesla C2070

>>> nvmlShutdown()
