我已經安裝了GPU tensorflow作爲tutorial。相對環境是：GPU tensorflow運行問題
Ubuntu 14 + cuda8.0 + cudnn5.0 + GeForce Gt 640 (OEM)
的問題是：
E tensorflow/stream_executor/cuda/cuda_driver.cc:491] failed call to cuInit: CUDA_ERROR_NO_DEVICE
I tensorflow/stream_executor/cuda/cuda_diagnostics.cc:153] retrieving CUDA diagnostic information for host: wangyajie

E tensorflow/stream_executor/cuda/cuda_diagnostics.cc:296] kernel version 340.98.0 does not match DSO version 352.63.0 -- cannot find working devices in this configuration
我能做些什麼來解決這個問題？ 我應該更新DSO嗎？如果應該，應該使用什麼命令？
如何檢查的天氣我安裝CUDA和cudnn是否正確？應該使用什麼命令？
在此先感謝！ ZhQ
