Xiaofan, If the parameters were correctly set, it seems that you have a wrong library linking (the shared library used in compilation is not the library you are currently linking to), or you compiled ALPS with some features that your CPU does not actually support. The ways to solve such problems are trying to: recompile ALPS, or set the correct shared library, which is purely technical work.

To whom it may concern,
When I use the mps_evolve to calculate the time evolution of Fermi-Hubbard, there are some problems that I can not solve. The python file and the error information are shown as follow.
