WebHi @jacquelinehong. CNNs are designed to take input an RGB image. In MNIST digit classification since the digits are in grayscale format that is why the input_shape for the network is defined as (28, 28, 1). So if your dataset consists of 300x300 RGB images then the input_shape for the CNN will be (300, 300, 3). Hope your doubt is cleared. WebI note that the y axis of the image is mapped in reverse, from 100-0 rather than 0-100, and the x axis is sized at 250. The image shape is (100, 250): IN []: img.shape OUT []: (100, … WebExplanation of the changes: The integral limits in the double integral are correct, so no need to reshape the data. The stream_sum calculation is correct and remains the same.; Instead of directly cumulating the stream_sum array, we need to multiply it by the dz and vmask arrays first to get the contribution of each vertical layer to the stream function.
