Doubt regarding dataset used in video

#1

I downloaded MNIST dataset from kaggle. On using the dataset, my results are different from sir’s results. Like, the shape of the dataset shown in video is different from the shape I obtained and the column headings obtained on using df.columns are also different.

Maybe I have downloaded the dataset from wrong source. Please tell where is the problem

You can download the dataset from here : http://yann.lecun.com/exdb/mnist/

Also the image size should be the same as (28*28) , the number of images in a dataset can vary from different sources. The larger the number of images, the better the dataset.
