I am trying to run mobility test, but I face this message:

"The network graph vertex count did not equal the number of nodes the graph was created from. This is an internal umi error and should be reported as a bug. In the meantime, try re-layering your model's streets."

and I cannot figure out where the problem is caused from. 

Please advise how I can fix it.

Sorry you're having trouble. This is a bug we still haven't been able to nail down. If you want to upload a file with the problem, I can take a look. Otherwise, others have had some success fixing it by redrawing their streets.

In Short

Umi is a Rhino-based design environment for architects and urban planners interested in modeling the environmental performance of neighborhoods and cities with respect to operational and embodied energy use, walkability and daylighting potential. Since 2012, Umi has been  developed by the Sustainable Design Lab at the Massachusetts Institute of Technology with support from a National Science Foundation EFRI_SEED project, the MIT Energy Initiative, the Kuwait-MIT Center, the Center for Complex Engineering Systems (CCES) at KACST and MIT, Transsolar Climate Engineering and United Technologies Corporation. Further tool developed is now also being conducted at the Environmental Systems Lab at Cornell University.

A first public version of Umi was released during a public symposium on Sustainable Urban Design on May 6th 2013 at the Massachusetts Institute of Technology. Version 2.0, which also includes an embodied energy module, was released on November 7th 2014.
