DREAMPlace: LEF/DEF Format error

Hi, Prof. Lin.

I really appreciate your help with the installation of our environment. However, I still have a problem when running DREAMPlace with LEF/DEF file format. I extracted LEF/DEF format file after macro placement of our chip design from IC Compiler II Tool.

But the result looks unnormal. The process is terminated with the below error.
