TensorFlow安裝筆記

紀錄在 windows 10 安裝 TensorFlow GPU 版本的過程

目錄

安裝

安裝TensorFlow

此筆記紀錄支援GPU的安裝版本,安裝環境GPU為GeForce GTX 750 Ti 繪圖卡。

安裝CUDA 8.0

下載、安裝

CUDA 8 下載網址: https://developer.nvidia.com/cuda-80-ga2-download-archive
此筆記選擇local版本安裝。

選擇所要的版本下載完成後,打開安裝程式,照著指示安裝。此筆記安裝選項選擇: 快速(建議)。
並安裝Patch 2 (Released Jun 26, 2017)做補丁更新。

檢查配置是否正確

檢查CUDA Toolkit的版本: 在命令提示字元中輸入 nvcc -V

驗證硬體與軟體的正確配置,官方文件強烈建議在預設路徑 C:\ProgramData\NVIDIA Corporation\CUDA Samples\v8.0\bin\win64\Release 中執行 DEVICEQUERY
筆者結果如下:

C:\ProgramData\NVIDIA Corporation\CUDA Samples\v8.0\bin\win64\Release>DEVICEQUERY

deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 8.0, CUDA Runtime Version = 8.0, NumDevs = 1, Device0 = GeForce GTX 750 Ti
Result = PASS

主要確保有偵測到與系統所安裝符合的設備,筆者即為GeForce GTX 750 Ti

若cmd找不到 DEVICEQUERY ,則到預設路徑 C:\ProgramData\NVIDIA Corporation\CUDA Samples\v8.0\1_Utilities\deviceQuery 找到與系統對應的VS版本.sln檔進行編譯,如筆者為VS2013版,包括Debug與Release皆進行編譯 [[1]]。編譯後即可回去執行 DEVICEQUERY

(另有 bandwidthTest 部分,cmd找不到,筆者未能理解,暫為保留)
(設定 $path 尚待理解,現確認有未新專案增加路徑與現存專案增加路徑2種)

安裝cuDNN 6.0

cuDNN下載網址: https://developer.nvidia.com/rdp/cudnn-download
需註冊nVIDIA developer帳號才能下載。

選擇符合的作業系統版本安裝,下載後為一個壓縮檔,將CUDA 資料夾裡面的3個資料夾: binincludelib,解壓縮至 C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0 中 [[2]]。此筆記使用cuDNN v6.0 (April 27, 2017), for CUDA 8.0

原生pip安裝TensorFlow

安裝

此筆記選擇GPU版本TensorFlow,使用以下指令:

C:\> pip3 install --upgrade tensorflow-gpu

此指令會下載最新的版本,筆者此時的版本為1.4

驗證安裝成功

shell裡啟動python(筆者使用cmd):

$ python

並在裡面輸入以下python程式碼:

>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))

若輸出為Hello, TensorFlow! 表示成功可執行。
