'predict' was not declared in this scope

hi yiakwy:

I configure the environment in ubuntu18.04 system as you say in README, all is well, and I encounter a error when I make build the project, the error log is as follow:

~/SEMANTIC_VISUAL_SUPPORTED_ODEMETRY/modules/models/linear/line.cpp: In member function 'void svso::models::linear::LinearModel::fit (const MatrixXd&, const VectorXd&)':
~/SEMANTIC_VISUAL_SUPPORTED_ODEMETRY/modules/models/linear/line.cpp:41:5: error: 'predict' was not declared in this scope
predict(X, fittedVals);
^~~~~~~
~/SEMANTIC_VISUAL_SUPPORTED_ODEMETRY/modules/models/linear/line.cpp:41:5: note: suggested alternative: 'pselect'
predict(X, fittedVals);
^~~~~~~
pselect

Is this syntax error ?
thanks.
