MatchZoo-py DSSM tutorial code: RuntimeError Expected object of scalar type Float but got scalar type Double

Describe the bug

When I run the tutorial code for DSSM, the following error appears:
RuntimeError: Expected object of scalar type Float but got scalar type Double for argument #2 'mat1' in call to _th_addmm

please find the details below:

Describe your attempts

I am trying to address this problem according to the following post: https://stackoverflow.com/questions/56741087/how-to-fix-runtimeerror-expected-object-of-scalar-type-float-but-got-scalar-typ/56741419

But it seems not working by adding float().
