ram not tensorflow檢測gpu

我最近添加了一個8GB的ram到我的電腦以方便計算，但是，儘管我的ubuntu識別它，但gpu tensorflow似乎並不認出它。這裏是我的結果運行sudo lshw -class memory 後，其結果是ram not tensorflow檢測gpu

*-memory 
    description: System Memory 
    physical id: 2c 
    slot: System board or motherboard 
    size: 16GiB 
*-bank:0 
     description: SODIMM Synchronous 2400 MHz (0.4 ns) 
     product: HMA81GS6AFR8N-UH 
     vendor: 009C35230000 
     physical id: 0 
     serial: 31D92036 
     slot: ChannelA-DIMM0 
     size: 8GiB 
     width: 64 bits 
     clock: 2400MHz (0.4ns) 
*-bank:1 
     description: SODIMM Synchronous 2400 MHz (0.4 ns) 
     product: CT8G4SFS824A.C8FAD1 
     vendor: 009D36160000 
     physical id: 1 
     serial: 156C0B48 
     slot: ChannelB-DIMM0 
     size: 8GiB 
     width: 64 bits 
     clock: 2400MHz (0.4ns)

然而，tensorflow不承認它，還是輸出如下

I tensorflow/core/common_runtime/gpu/gpu_device.cc:885] Found device 0 with properties:

的GPU是否有我需要做任何額外的步驟得到我的全部公羊認可？

GPU RAM和系統RAM是兩件不同的東西
