This line of code is reshaping the x_train dataset to have an additional dimension of size 1. It is being done using the reshape() method of the numpy library.
The first argument to reshape() specifies the new shape of the array, which is being set to (x_train.shape[0], x_train.shape[1], 1). This means that the new array will have the same number of rows as the original x_train array, the same number of columns as the original x_train array, and an additional dimension of size 1.
The second argument to reshape() is optional and specifies the order in which the elements of the original array should be arranged in the new array. In this case, it is not specified so the default value 'C' is used, which means that the elements will be arranged in row-major order.
