Defined in tensorflow/contrib/kfac/python/ops/utils.py.

Converts a vector shaped like layer parameters to a 2D matrix.

In particular, we reshape the weights/filter component of the vector to be 2D, flattening all leading (input) dimensions. If there is a bias component, we concatenate it to the reshaped weights/filter component.


  • vector: A Tensor or pair of Tensors shaped like layer parameters.


A 2D Tensor with the same coefficients and the same output dimension.
