tf.reduce_mean
reduce_mean(
input_tensor,
axis=None,
keep_dims=False,
name=None,
reduction_indices=None
)
Defined in tensorflow/python/ops/math_ops.py.
See the guide: Math > Reduction
Computes the mean of elements across dimensions of a tensor.
input_tensor
along the dimensions given in axis
. Unless keep_dims
is true, the rank of the tensor is reduced by 1 for each entry in axis
. If keep_dims
axis
For example:
# 'x' is [[1., 1.]
# [2., 2.]]
tf.reduce_mean(x) ==> 1.5
tf.reduce_mean(x, 0) ==> [1.5, 1.5]
tf.reduce_mean(x, 1) ==> [1., 2.]
Args:
input_tensor
- : The tensor to reduce. Should have numeric type.
axis
- : The dimensions to reduce. If
None
keep_dims
- : If true, retains reduced dimensions with length 1.
name
- : A name for the operation (optional).
reduction_indices
- : The old (deprecated) name for axis.
Returns:
The reduced tensor.
numpy compatibility
Equivalent to np.mean
不翻译了,这个就是计算向量均值的,加各种参数按各种方式计算均值,不懂再交流
