Try using ImageCms from PIL to do the profile conversion:

from PIL import Image
from PIL import ImageCms
import numpy

img_path = 'input.png'

def cmyk_to_rgb(cmyk_img):
    img = Image.open(cmyk_img)
    if img.mode == "CMYK":
        img = ImageCms.profileToProfile(img, "Color Profiles\\USWebCoatedSWOP.icc", "Color Profiles\\sRGB_Color_Space_Profile.icm", outputMode="RGB")
    return numpy.array(img)

orig_img = cmyk_to_rgb(str(img_path))
pilImage = Image.fromarray(orig_img)
pilImage.save('output.png')
