Whether displaying it on a screen or feeding it to a neural network, it is fundamental to have a tool to turn the stored bytes into a meaningful representation. A solution is to read the bytes that we need when we need them directly from Blob Storage. open ( "container/file.svs" ) as f : # read the first 256 bytes print ( f.
