   It seems the file is lost, but you can recreate it. Basically, mean.bin is a mean image: every pixel of this image is a mean value of pixels on that position of all training images. That mean image is used to normalize every image during training and prediction.
   
   You can recreate this file by:
   - Take all training images tensors and sum them up
   - Divide resulting tensor to number of training images 
   - Resulting tensor is a mean image - save it to file with mean.bin file name.
   
   Also, if you do all of this and it will work, please contribute back to S3!
