Error in loading of image files

[rishabh prakash]

I installed this amazing software package on my Linux machine but when I run the SimVascular application using ubuntu terminal every thing looks good but after opening the SimVascular, no numpy module found while I already installed numpy and second error is none of the option is working. Each option is showing "Error, Invalid Command". I attached my script file and error image.
