• 原型

      tf.squeeze(input, squeeze_dims=None, name=None)

      从tensor中删除所有大小是1的维度

      给定张量输入，此操作返回相同类型的张量，并删除所有尺寸为1的尺寸。 如果不想删除所有大小是1的维度，可以通过squeeze_dims指定。

 

• 参数解释

1. input: A Tensor. The input to squeeze. 
2. squeeze_dims: An optional list of ints. Defaults to []. If specified, only squeezes the dimensions listed. The dimension index starts at 0. It is an error to squeeze a dimension that is not 1. 
3. name: A name for the operation (optional).

 

• 示例

# \'t\' is a tensor of shape [1, 2, 1, 3, 1, 1]
shape(squeeze(t)) ==> [2, 3]
Or, to remove specific size 1 dimensions:

# \'t\' is a tensor of shape [1, 2, 1, 3, 1, 1]
shape(squeeze(t, [2, 4])) ==> [1, 2, 3, 1]
