How to use my own images to train the model

Hello,

I am trying to use your code to train my own images (https://github.com/oist/Usiigaci/blob/master/Mask%20R-CNN/samples/shapes/train_shapes.ipynb). But I had some issues loading the image with mask by the path. Can you tell me how to achieve it, please? 

Thanks!
Thiem
