title: I have converted 3 channel RGB image into 2 channels grayscale image, How to decrease greyscale channels to 1?
body: <p>I have Converted 3 Channel RGB image into 2 channel grayscale image using :</p>
  
  <pre class="lang-py prettyprint-override"><code>from PIL import Image
  import glob
  images = glob.glob('C:/Users/.../*.jpg')
  for i in range(len(images)):
      img = Image.open(images[i]).convert('LA')
      img = img.resize((224,224),Image.ANTIALIAS)
      img.save('C:/Users/.../0_{}.png'.format(i))
  </code></pre>
  
  <p>My Goal was to create 1 channel grayscale but after doing code above, i found out that results are 2 channels images ! is there any way that i can decrease this channels to 1 as if i converted them from 3 to 1 at first place ?
  Thanks.</p>
