tf.contrib.kfac.utils.column_to_tensors( tensors_template, colvec )
Converts a column vector back to the shape of the given template.
tensors_template: A tensor or list of tensors.
colvec: A 2d column vector with the same shape as the value of tensors_to_column(tensors_template).
X, where X is tensor or list of tensors with the properties: 1) tensors_to_column(X) = colvec 2) X (or its elements) have the same shape as tensors_template (or its elements)
