Tensorflow 1.13.1无法识别GPU

Question

我有GPU NVIDIA GeForce GT 740M（计算能力3.0）和以下版本的CUDA，cuDNN和tensorflow安装。

nvsk -V

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Fri_Feb__8_19:08:17_PST_2019
Cuda compilation tools, release 10.1, V10.1.105

cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

#define CUDNN_MAJOR 7
#define CUDNN_MINOR 5
#define CUDNN_PATCHLEVEL 0
--
#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)

#include "driver_types.h"

pip3显示tensorflow-gpu

Version: 1.13.1

pip3显示tensorflow

Name: tensorflow
Version: 1.13.1

但是当我通过print（device_lib.list_local_devices（））检查tensorflow检测到的设备时，输出如下......

[name: "/device:CPU:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}
incarnation: 13567978771733496471
, name: "/device:XLA_CPU:0"
device_type: "XLA_CPU"

locality {
}
incarnation: 12191851301991039336
physical_device_desc: "device: XLA_CPU device"
]

如何让tensorflow看到GPU？

附： tensorflow-gpu是在tensorflow之前安装的，所以按顺序重新安装“1）tensorflow-gpu 2）tensorflow”效率低下

Answer 1

tensorflow需要计算能力+3.2。

你有一个具有计算能力3.0的GPU
