2020-06-16 17:38:08
本文介紹TensorFlow原始碼方式安裝。安裝的系統為 Ubuntu 15.04。
獲取TensorFlow原始碼
1
|
git clone --recurse-submodules https: //github .com /tensorflow/tensorflow |
使用 --recurse-submodules
選項來獲取 TensorFlow 需要依賴的 protobuf 庫檔案。
安裝 Bazel
遵從以下 指令 來安裝 bazel 依賴。bazel 安裝檔案:下載地址
bazel 預設需要使用JDK1.8,如你使用JDK1.7,請下載相應的安裝包。
安裝 Bazel 其他所需依賴:
1
|
sudo apt-get install pkg-config zip g++ zlib1g-dev unzip |
執行如下命令來安裝Bazel:
1
2
|
chmod +x PATH_TO_INSTALL.SH . /PATH_TO_INSTALL .SH --user |
記住把 PATH_TO_INSTALL.SH 替換為你下載的Bazel安裝檔名,如:
1
|
. /bazel-0 .1.4-installer-linux-x86_64.sh --user |
安裝其他依賴

設定安裝
執行 tensorflow 根目錄下的 configure
指令碼。這個指令碼會要求你輸入 python 直譯器的安裝路徑,並允許你可選擇安裝CUDA庫。
如果不安裝CUDA,則這一步主要是定位python和numpy標頭檔案所在位置:
1
2
|
. /configure Please specify the location of python. [Default is /usr/bin/python ]: |
如果要安裝CUDA,則除了指定 python 外,還需指定 CUDA 安裝位置:

. /configure Please specify the location of python. [Default is /usr/bin/python ]: Do you wish to build TensorFlow with GPU support? [y /N ] y GPU support will be enabled for TensorFlow Please specify the location where CUDA 7.0 toolkit is installed. Refer to README.md for more details. [default is: /usr/local/cuda ]: /usr/local/cuda Please specify the location where the cuDNN v2 library is installed. Refer to README.md for more details. [default is: /usr/local/cuda ]: /usr/local/cuda Setting up Cuda include Setting up Cuda lib64 Setting up Cuda bin Setting up Cuda nvvm Configuration finished |
構建支援GPU的Tensorflow
在tensorflow 根目錄下執行如下命令:
$ bazel build -c opt --config=cuda --spawn_strategy=standalone //tensorflow/cc:tutorials_example_trainer
$ bazel-bin/tensorflow/cc/tutorials_example_trainer --use_gpu
# Lots of output. This tutorial iteratively calculates the major eigenvalue of
# a 2x2 matrix, on GPU. The last few lines look like this.
000009/000005 lambda = 2.000000 x = [0.894427 -0.447214] y = [1.788854 -0.894427]
000006/000001 lambda = 2.000000 x = [0.894427 -0.447214] y = [1.788854 -0.894427]
000009/000009 lambda = 2.000000 x = [0.894427 -0.447214] y = [1.788854 -0.894427]
Note that "--config=cuda" is needed to enable the GPU support.
