TypeError: 'dict_items' object is not subscriptable

[root-sudip]

I was doing exactly same code that has in the example in selectivesearch.

here is the code,

import skimage.data
import matplotlib.pyplot as plt
import matplotlib.patches as mpatches
from selectivesearch import selective_search


def main():

    # loading astronaut image
    img = skimage.data.astronaut()

    # perform selective search
    img_lbl, regions = selective_search(img, scale=500, sigma=0.9, min_size=10)

    candidates = set()
    for r in regions:
        # excluding same rectangle (with different segments)
        if r['rect'] in candidates:
            continue
        # excluding regions smaller than 2000 pixels
        if r['size'] < 2000:
            continue
        # distorted rects
        x, y, w, h = r['rect']
        if w / h > 1.2 or h / w > 1.2:
            continue
        candidates.add(r['rect'])

    # draw rectangles on the original image
    fig, ax = plt.subplots(ncols=1, nrows=1, figsize=(6, 6))
    ax.imshow(img)
    for x, y, w, h in candidates:
        print(x, y, w, h)
        rect = mpatches.Rectangle(
            (x, y), w, h, fill=False, edgecolor='red', linewidth=1)
        ax.add_patch(rect)

    plt.show()

if __name__ == "__main__":
    main()

and getting this error,

Traceback (most recent call last):
  File "selective_search.py", line 41, in <module>
    main()
  File "selective_search.py", line 13, in main
    img_lbl, regions = selective_search(img, scale=500, sigma=0.9, min_size=10)
  File "/usr/local/lib/python3.5/dist-packages/selectivesearch/selectivesearch.py", line 274, in selective_search
    neighbours = _extract_neighbours(R)
  File "/usr/local/lib/python3.5/dist-packages/selectivesearch/selectivesearch.py", line 208, in _extract_neighbours
    for cur, a in enumerate(R[:-1]):
TypeError: 'dict_items' object is not subscriptable

To fix this error, I have changed the line number 206 of selectivesearch.py by this line R = list(regions.items())
Now I am getting this error,

Traceback (most recent call last):
  File "selective_search.py", line 41, in <module>
    main()
  File "selective_search.py", line 13, in main
    img_lbl, regions = selective_search(img, scale=500, sigma=0.9, min_size=10)
  File "/usr/local/lib/python3.5/dist-packages/selectivesearch/selectivesearch.py", line 286, in selective_search
    i, j = sorted(S.items(), cmp=lambda a, b: cmp(a[1], b[1]))[-1][0]
TypeError: 'cmp' is an invalid keyword argument for this function

How do I fix this problem ??
