Apologies this is not necessarily related to processing, I just couldn’t find an answer online.

I’ve only used mnist data with Python and Keras. But funny enough same question has been asked before and you can find there how to use mnist with processing.

How do I import an "idx3-ubyte" file?

I am wondering how to import the files found on this website into Processing: http://yann.lecun.com/exdb/mnist/ They’re supposed to contain thousands of 28x28 byte arrangements, each with its own “grayscale” value. In essence, they’re images. But the files don’t have a .dat extension, an extension I’ve learned to use thanks to the saveBytes() and loadBytes() reference tutorials on the Processing website. I don’t know what an .idx3-ubyte extension is and how to import it into an arbitrary Proce…

thanks for this, I figured out how to read the data, I was just wandering if a specific benefit to using the ubyte format over a traditional image format?
