Tensorflow 1.13.1无法识别GPU

Question

I have GPU NVIDIA GeForce GT 740M (compute capability 3.0) and the following versions of CUDA, cuDNN and tensorflow installed.

nvcc -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 show tensorflow-gpu

pip3 show tensorflow

But when I check devices detected by tensorflow with print(device_lib.list_local_devices()), the output is as follows...

[name: "/device:CPU:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}
incarnation: 13567978771733496471
, name: "/device:XLA_CPU:0"
device_type: "XLA_CPU"
memory_limit: 17179869184
locality {
}
incarnation: 12191851301991039336
physical_device_desc: "device: XLA_CPU device"
]

How can I make tensorflow see GPU?

ps tensorflow-gpu was installed before tensorflow, so re-installing in order "1) tensorflow-gpu 2) tensorflow" is inefficient

Answer 1

tensorflow need compute capability +3.2.

you have a GPU with compute capability 3.0
