title: What is 'filename' in the code of Transfer Learning using MNIST dataset?
body: <p>The code for classification of MNIST dataset using Transfer Learning is given in the link <a href="https://www.analyticsvidhya.com/blog/2017/06/transfer-learning-the-art-of-fine-tuning-a-pre-trained-model/" rel="nofollow noreferrer">https://www.analyticsvidhya.com/blog/2017/06/transfer-learning-the-art-of-fine-tuning-a-pre-trained-model/</a></p>
  
  <p>I am not able to understand what 'filename' stands in the code? Also, why the dataset is loaded twice in the code.</p>
  
  <p>I have seen code using load_img() function but still, I am not able to run the given code without error as 'filename' is unknown as it is not defined in the link.</p>
  
  <p>The MNIST dataset consists of two files 'mnist_train.csv' and 'mnist_test.csv'. There is code where the .csv files are being converted into images but then they have a single .csv file for every image. Here, there are only two .csv files for all the images present in train and test.  </p>
  
  <p>Thanks in advance!</p>
