title: Tensorflow: Do created TFRecords files always have a larger file size than the original data?
body: <p>If I have an folder of jpg images 5gb in size in total, and I convert my files into TFRecords, splitting it into 280 for training, 120 for validation, and 100 for test, is the total file size of the 3 created TFrecords files always larger than 5Gb?</p>
  
  <p>Because currently I am having a tfrecords file of ~100mb for the training file, and around 40-50mb for the validation and test files. I suspect the files may be created wrongly but I have no way of verifying it. Thus, if a combined file size of the 3 tfrecords files is lesser than 5gb, does this mean the files are created wrong?</p>
  
  <p>How can I check further whether the files have read the correct data? (could I read the data from a tfrecords file? So far, the shapes for the tensor data are correct.)</p>
