Description 张浩 2019-01-26 18:07:25 UTC 
current master branch

this file:
unsupported/Eigen/CXX11/src/Tensor/TensorContraction.h

line 105
it says
  static const int NumDimensions = traits<RhsXprType>::NumDimensions + traits<RhsXprType>::NumDimensions - 2 * array_size<Dimensions>::value;

it shoud be
  static const int NumDimensions = traits<LhsXprType>::NumDimensions + traits<RhsXprType>::NumDimensions - 2 * array_size<Dimensions>::value;

Seems plausible to me. Could you provide a unit-test which exposes the error?
