Placeholder issue

Hi, I am trying to run this on colab. But I'm getting the following error:
**** EPOCH 000 ****
2020-10-01 02:31:34.986664
Traceback (most recent call last):

ValueError: Cannot feed value of shape (32, 2048, 3) for Tensor 'Placeholder:0', which has shape '(32, 2048, 4)'

Can anyone suggest me any way? Thanks in advance
