Google cloud platform 谷歌云特斯拉K80，只有一台设备出现？

我在Google Cloud上安装了一个实例，其规格如下： 4个VCPU，15 GB内存，1个特斯拉K80 GPU

特斯拉K80由2个GPU单元组成，每个GPU单元应在nvidia的日志中显示为单独的设备。但是，当我在shell中运行nvidia smi时，它只显示一个。 图片：

有人知道如何解决这个问题吗？这是因为我的云GPU配额是一个，因此只使用了一个设备吗

通过挖掘云平台网站，我找到了答案。我没有删除这个问题，而是把它留在这里，以防其他人面临同样的问题

特斯拉K80是由2个GPU组成的“1 GPU板”。如果您在Google云平台上的VM实例上的GPU数量设置为1，您将被分配1个GPU或半块板
