the value of validation data is invalid. augmenetedImageDataStore cannot form MiniBatches of data because input image sizes differ in 3rd dimension. Consider using colorPreprocessing option to ensure all augmented images have same number of channels.
this is the error raised while training my own image dataset.help me?

It seems that the images in Input dosen't have consistent channel. To know more on RGB channel you can go to this link. augmentedimagedatastor works only with consistent number of channel in each image. Please use ColorPrerocessing to make channel consistent. For more information you can look into the following link.

Hi!
I did not understand how to do the ColourPreprocessing as I already read all the link you gave. But still I didn't understand how to do it. I'm trying to train the network using Deep Network Design Toolbox. Please help me to fix this problem. Thank you
