tf.squeeze()

Ref:

tf.squeeze()

Function

tf.squeeze(input, squeeze_dims=None, name=None)
Removes dimensions of size 1 from the shape of a tensor.
从tensor中删除所有大小是1的维度
Given a tensor input, this operation returns a tensor of the same type with all dimensions of size 1 removed. If you don’t want to remove all size 1 dimensions, you can remove specific size 1 dimensions by specifying squeeze_dims. 
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。 如果不想删除所有尺寸1尺寸，可以通过指定squeeze_dims来删除特定尺寸1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。
For example:
  1. # 't' is a tensor of shape [1, 2, 1, 3, 1, 1]
  2. shape(squeeze(t)) ==> [2, 3]
  3. Or, to remove specific size 1 dimensions:
  5. # 't' is a tensor of shape [1, 2, 1, 3, 1, 1]
  6. shape(squeeze(t, [2, 4])) ==> [1, 2, 3, 1]
