use tensor flow's inception v3 to classify handwritten letters

convert png to jpg find . -iname '.png' | while read i; do mogrify -format jpg "$i" && rm "$i"; echo "Converted $i to ${i%.}.jpg"; done

remove files which has fewer than 20 images, because Inception v3 models only work on the files of more than 20 images.
