You need to install package Pillow for supporting Images in openpyxl

[nenetto]

In dqc_utils if you change line 275-

img = openpyxl.drawing.image.Image(os.path.join(img_dir, '%s.png' %(graph_name))) ws.add_image(img, 'C%d' %(head_row+1)) except Exception as e: print(e) continue

It ask for PIL package to print images in XLS. Solve that installing Pillow

pip install Pillow
