hello，when i test a 532*570 image， it happens that “Cannot feed value of shape (1, 720, 1280, 4) for Tensor 'Placeholder:0', which has shape '(1, 720, 1280, 3)'”，what‘s the matter？How can solve this problem?

And maybe your image has 4 channels, try to convert to RGB images first: you can slice first 3 channels or use opencv
