title: Turning a Large Matrix into a Grayscale Image
body: <p>I have a NumPy array of 3,076,568 binary values (1s and 0s). I would like to convert this to a matrix, and then to a grayscale image in Python.</p>
  
  <p>However, when I try to reshape the array into a 1,538,284 x 1,538,284 matrix, I get a memory error.</p>
  
  <p>How can I reduce the size of the matrix so that it will turn into an image that will fit on a screen without losing the uniqueness/data?</p>
  
  <p>Furthermore, how would I turn it into a grayscale image?</p>
  
  <p>Any help or advice would be appreciated. Thank you.</p>
