I have NumPy array of float X_train shape: (6000,2304) I need to convert it into (6000,48,48,1)

I have read image data from CSV file which has row vector of all images. I made NumPy array from that but I need to pass this into the convolutional neural network which needs 4D array.

What's wrong with using `.reshape`? – PM 2Ring Jan 18 '18 at 11:30

To extend on @PM2Ring 's comment: `a.reshape(6000,48,48,1)` – Thomas Kühn Jan 18 '18 at 12:07
