OSError: Unable to open file (file signature not found)

See original GitHub issue

When I run this sample Usage

import numpy as np
from PIL import Image

img = Image.open(r'MyJPG_Path')
lr_img = np.array(img)

from ISR.models import RDN

rdn = RDN(arch_params={'C':6, 'D':20, 'G':64, 'G0':64, 'x':2})
rdn.model.load_weights('weights/sample_weights/rdn-C6-D20-G64-G064-x2/ArtefactCancelling/rdn-C6-D20-G64-G064-x2_ArtefactCancelling_epoch219.hdf5')
sr_img = rdn.predict(lr_img)
Image.fromarray(sr_img)

It warns that:

Traceback (most recent call last):
  File "test.py", line 12, in <module>
    rdn.model.load_weights('weights/sample_weights/rdn-C6-D20-G64-G064-x2/ArtefactCancelling/rdn-C6-D20-G64-G064-x2_ArtefactCancelling_epoch219.hdf5')

I use the original hdf5 file which is downloaded from the Github source. I wonder how to cope with this problem.
