Hi,

The output that you provide doesn’t show any useful debugging information, except that you are using Windows and that the scripts failed in the second part, i.e. where it is loading and evaluating the results.

I guess that something went wrong in the first part, i.e. when the mps_optim application was executed.

A common problem (but I’m not sure it is your problem) is that the latest Windows binaries contain an old (draft) version of the MPS applications. To be sure this is not your problem you should try out the 2.2b4 release, that you can try compiling from sources, e.g. in a Linux virtual machine, or using the Mac binaries.

Best regards, Michele

Dear All, I try the example script provided by alps. But the following information shows that there is an error. I attach the spin_one.py, which can also be found in the alps. What is the problem? Thank you very much.

Sincerely, Huaiming Guo
