报错AttributeError: 'Tensor' object has no attribute 'numpy'
    解决：tf.enable_eager_execution()
    拓展：获取tensor类型的变量值
    
    方法一：在会话中print( sess.run(x) )
    	import tensorflow as tf
    	#定义tensor常量
    	x = tf.random_uniform((2, 3), -1, 1)
    	#开启会话
    	with tf.Session() as sess:
    	    print (sess.run(x))
    	#[[ 0.46468353 -0.61598516 -0.9036629 ]
    	# [ 0.68292856  0.65335464  0.00641084]]
    	
    方法二：使用.eval()相当于将tensor类数据转为numpy，再输出
    	import tensorflow as tf
    	#定义tensor常量
    	x = tf.random_uniform((2, 2), -1, 1)
    	#开启会话
    	with tf.Session() as sess:
    		print (x.eval())
    	#[[-0.8492842   0.50390124]
             # [-0.9012234   0.77892494]]
    
    方法三：
        开启紧急执行
        tf.enable_eager_execution()
    
    方法四：
        tensor类型变量.numpy()
