Testing Gazefollow

[Unfazed Max]

Hey Guys
I'm trying to install the Caffe model to test Gazefollow. but for some reason, it doesn't seem to work. I installed Nvidia CUDA, CUDNN, MatLab 2018a and visual studio 2019.
This is the error I get when I try to run the demo file.

User selected G:\ImageProcessing\task\task\Input.png

  In imshow (line 336)

  In demo (line 14)
