Tensorflow 1.13.1無法識別GPU

Question

我安裝了GPU NVIDIA GeForce GT 740M（計算能力3.0）以及以下版本的CUDA，cuDNN和tensorflow。

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

貓/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

Name: tensorflow-gpu
Version: 1.13.1

pip3顯示tensorflow

Name: tensorflow
Version: 1.13.1
Summary: TensorFlow is an open source machine learning framework for everyone.

但是當我使用print（device_lib.list_local_devices（））檢查tensorflow檢測到的設備時，輸出如下...

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

我怎樣才能使Tensorflow看到GPU？

ps tensorflow-gpu是在tensorflow之前安裝的，因此按“ 1）tensorflow-gpu 2）tensorflow”的順序重新安裝效率很低

Answer 1

張量流需要計算能力+3.2。

您有一個具有計算能力3.0的GPU
