TypeError: Input Image Tensor Channel Error (1, 3 Expected, Found 4) - Solution & Explanation

This error occurs when the input image tensor has 4 channels, but only 1 or 3 channels are expected. \n\nIn computer vision, an image is typically represented as a tensor with three dimensions: height, width, and channels. The number of channels represents the color information in the image. For example, grayscale images have 1 channel, while RGB images have 3 channels.\n\nTo fix this error, you need to ensure that the input image tensor has either 1 or 3 channels. If you have an image with 4 channels, you can convert it to 1 or 3 channels depending on your requirements.
