** pyhessian

This package `pyhessian' contains the following components:
      A python3 module to estimate Hessian matrices using TensorFlow
      ( and NumPy (

      An example showing how to apply HessianEstimator on
      a feed-forward neural network TensorFlow model

pyhessian is written in Python3 and depends on the TensorFlow and
NumPy libraries.

pyhessian is a module used to estimate Hessian matrices of TensorFlow
models. See the accompagnying paper "Efficient Computation of Hessian Matrices
in TensorFlow" found at:
