viz2code status report error

[HyunwooCho]

I made a very simple network, composing of 'Conv2d' and 'MaxPool2d' in Visualization. When I clicked 'Generate' button, viz2code was trying to export JSON file but failed to report status 'completed' to Project Manager.

They look up model 'StatusList' to report status. but they did not save any, so get_status(len(get_status)-1] refers -1 (negative index).
