第1章 TensorFlow基础学习

1.1 1TensorFlow Python 库安装

1)  pip install wheel

2)  download  tensorflow-.whl file

a)     https://ci.tensorflow.org/view/Nightly/job/nightly-matrix-cpu/TF_BUILD_IS_OPT=OPT,TF_BUILD_IS_PIP=PIP,TF_BUILD_PYTHON_VERSION=PYTHON2,label=mac-slave/lastSuccessfulBuild/artifact/pip_test/whl/tensorflow-1.0.1-py2-none-any.whl

b)    https://ci.tensorflow.org/view/Nightly/job/nightly-matrix-cpu/TF_BUILD_IS_OPT=OPT,TF_BUILD_IS_PIP=PIP,TF_BUILD_PYTHON_VERSION=PYTHON2,label=mac-slave/lastSuccessfulBuild/artifact/pip_test/whl/tensorflow-1.head-py2-none-any.whl

3)  Install tensorflow

a)     pip install tensorflow-1.head-py2-none-any.whl 

b)    pip install tensorflow-1.0.1-py2-none-any.whl

c)     pip install --ignore-installed--upgrade    https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.0.1-cp27-none-linux_x86_64.whl(验证通过)

d)     

4)  验证模块是否可以用

importtensorflow as tf

    hello = tf.constant('Hello, TensorFlow!')

    sess = tf.Session()

           print(sess.run(hello))

              b =tf.constant(100)

       a = tf.constant200

       printsess.run(a+b)

1.2 Win10 安装tensorflow

1)   安装Python3.5 匹配CP35版本的TensorFlow

2)   安装vc2015 版本

3)   工具下载

a)     https://download.microsoft.com/download/6/D/F/6DF3FF94-F7F9-4F0B-838C-A328D1A7D0EE/vc_redist.x64.exe

b)    https://www.python.org/ftp/python/3.5.3/python-3.5.3-amd64.exe

4)   安装tensorflow

a)     pip install --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-0.12.0-cp35-cp35m-win_amd64.whl

Error importing tensorflow.  Unless you are using bazel,
you should not try to import tensorflow from its source directory;
please exit the tensorflow source tree, and relaunch your python interpreter
from there.

解决办法:

    

1)ImportError: No module named '_pywrap_tensorflow' 

    a)Download : https://download.microsoft.com/download/6/D/F/6DF3FF94-F7F9-4F0B-838C-A328D1A7D0EE/vc_redist.x64.exe 

    b)安装vc_redist.x64.exe

2)Import tensorflow
