Slowfast gradcam

Webb1 apr. 2024 · 1. I have trained a model to figure out if an image is right or wrong (just 2 classes) and I have used the guide on keras website for GradCAM . The input images are reshaped to (250, 250) and then normalized by dividing the image numpy array by 255. This is then passed for the training of the model. Here is the code attached.
