d.each do |year, month|
  # For Year

wish of those help If you're using Python 3.5+ you can use the bytes.fromhex method to convert hex string to bytes, and use the list constructor to convert bytes into a list of integers:
>>> list(bytes.fromhex('7f33117cf266a525'))
[127, 51, 17, 124, 242, 102, 165, 37]
>>> bytes([127, 51, 17, 124, 242, 102, 165, 37]).hex()

wish help you to fix your issue You can do it in two ways:
You can use opencv for this. To converts the image from Gray to RGB:
import cv2
import numpy as np
gray = np.random.rand(256, 256)
gary2rgb = cv2.cvtColor(gray,cv2.COLOR_GRAY2RGB)
import numpy as np
def convert_gray2rgb(image):
    width, height = image.shape
    out = np.empty((width, height, 3), dtype=np.uint8)
    out[:, :, 0] = image
    out[:, :, 1] = image
    out[:, :, 2] = image
    return out

gray = np.random.rand(256, 256)  # gray scale image
gray2rgb = convert_gray2rgb(gray)
