1.linux 安装tensorflow
ubuntu中安装：link
用pip安装的过程中，可能出现网络链接的问题，尝试多次链接，直到成功！！！
python -V sudo apt-get install python-pip python-dev
problem：关于python升级，和pip正常使用。细节：请看python升级。
demo：
$ python >>> import tensorflow as tf >>> hello = tf.constant(‘Hello, TensorFlow!‘) >>> sess = tf.Session() >>> sess.run(hello) Hello, TensorFlow! >>> a = tf.constant(10) >>> b = tf.constant(32) >>> sess.run(a+b) 42 >>>
$ vim tensorboard_test.py tensorboard_test.py import tensorflow as tf import numpy as np WW = np.array([[0.1, 0.6, -0.9], [0.2, 0.5, -0.8], [0.3, 0.4, -0.7], [0.4, 0.3, -0.6], [0.5, 0.2, -0.5]]).astype(np.float32) bb = np.array([0.3, 0.4, 0.5]).astype(np.float32) x_data = np.random.rand(100,5).astype(np.float32) y_data = np.dot(x_data, WW) + bb with tf.Session() as sess: W = tf.Variable(tf.random_uniform([5,3], -1.0, 1.0)) # The zeros set to zero with all elements. b = tf.Variable $ python tensorboard_test.py
