Witryna5 Answers. Since you trained your model on mini-batches, your input is a tensor of shape [batch_size, image_width, image_height, number_of_channels]. When predicting, you have to respect this shape even if you have only one image. Your input should be of shape: [1, image_width, image_height, number_of_channels]. You can do this in … Witryna14 maj 2024 · By reading the image as a NumPy array ndarray, various image processing can be performed using NumPy functions.
