Hi, I am using this https://github.com/WalterMa/gluon-faster-rcnn repo for doing Faster rcnn task on my own dataset.
I have done training on my own dataset and i got 70% accuracy after 4 epochs…
I want to visualize the output… so i tried with demo script… i gave 1 input image and tried with the trained model. i changed the class names in demo script.
but i got this error… Could you please let me know whats the problem… Thank You
