tf.size

简介:
size(input, name=None, out_type=tf.int32)
    Returns the size of a tensor.
    
    Returns a 0-D `Tensor` representing the number of elements in `input`
    of type `out_type`. Defaults to tf.int32.
    
    For example:
    
    ```python
    t = tf.constant([[[1, 1, 1], [2, 2, 2]], [[3, 3, 3], [4, 4, 4]]])
    tf.size(t)  # 12
    ```
    
    Args:
      input: A `Tensor` or `SparseTensor`.
      name: A name for the operation (optional).
      out_type: (Optional) The specified non-quantized numeric output type
        of the operation. Defaults to `tf.int32`.
    
    Returns:
      A `Tensor` of type `out_type`. Defaults to `tf.int32`.
    
    @compatibility(numpy)
    Equivalent to np.size()
    @end_compatibility

Expected more than 1 value per channel when training, got input size torch.Size
因为模型中用了batchnomolization,训练中用batch训练的时候当前batch恰好只含一个sample,而由于BatchNorm操作需要多于一个数据计算平均值,因此造成该错误。

pytorch报错 RuntimeError: The size of tensor a (25) must match the size of tensor b (50) at non-singleton dimension 1 怎么解决?
这个错误提示表明,在进行某个操作时,张量a和b在第1个非单例维(即除了1以外的维度)上的大小不一致。例如,如果a是一个形状为(5, 5)的张量,而b是一个形状为(5, 10)的张量,则在第二个维度上的大小不匹配。
