 切记：tensorflow中大小写非常有区别！！

3.2. 变量:创建、初始化、保存和加载:

tf.Variable

6.3.1 ARRAY OPS

tf.reshape(tensor, shape, name=None)

6.3.2. CLIENT

class tf.Session

tf.Session.run(fetches, feed_dict=None)

6.3.3. CONSTANT OP:

tf.random_uniform(shape, minval=0.0, maxval=1.0, dtype=tf.float32, seed=None, name=None)

tf.zeros(shape, dtype=tf.float32, name=None)

tf.constant(value, dtype=None, shape=None, name=\'Const\')

6.3.5 FRAMWORK

3.2. 变量:创建、初始化、保存和加载:

class tf.Variable

http://www.tensorfly.cn/tfdoc/api_docs/python/array_ops.html#reshape

6.3.1 ARRAY OPS

tf.reshape(tensor, shape, name=None)

https://blog.csdn.net/lxg0807/article/details/53021859

http://www.tensorfly.cn/tfdoc/api_docs/python/array_ops.html#reshape

6.3.2. CLIENT

class tf.Session

tf.Session.run(fetches, feed_dict=None):

http://www.tensorfly.cn/tfdoc/api_docs/python/client.html#Session

6.3.3. CONSTANT OP:

tf.random_uniform(shape, minval=0.0, maxval=1.0, dtype=tf.float32, seed=None, name=None):

Outputs random values from a uniform distribution.(从均匀分布中输出随机值)

The generated values follow a uniform distribution in the range [minval, maxval). The lower bound minval is included in the range, while the upper bound maxval is excluded.

http://www.tensorfly.cn/tfdoc/api_docs/python/constant_op.html#random_uniform

tf.random_normal(shape, mean=0.0, stddev=1.0, dtype=tf.float32, seed=None, name=None)

• mean: A 0-D Tensor or Python value of type dtype. The mean of the normal distribution(正态分布的均值)
• stddev: A 0-D Tensor or Python value of type dtype. The standard deviation of the normal distribution(正态分布的标准差).

http://www.tensorfly.cn/tfdoc/api_docs/python/constant_op.html#random_normal

tf.zeros(shape, dtype=tf.float32, name=None)

http://www.tensorfly.cn/tfdoc/api_docs/python/constant_op.html#zeros 

tf.constant(value, dtype=None, shape=None, name=\'Const\')

 

注意：上面tf.constant()中参数指出shape的必要性，参数对应！

tf.placeholder(dtype, shape=None, name=None)

Inserts a placeholder for a tensor that will be always fed.
