scipy.io.matlab.miobase.MatReadError: Mat file appears to be empty

[trickyMan]

Hi, I encounter an issue, When I run selective_search.py , Here is the print.
`[root@localhost selective_search_ijcv_with_python-master]# python selective_search.py

Traceback (most recent call last):
File "selective_search.py", line 62, in
boxes = get_windows(image_filenames)
File "selective_search.py", line 41, in get_windows
all_boxes = list(scipy.io.loadmat(output_filename)['all_boxes'][0])
File "/usr/lib64/python2.7/site-packages/scipy/io/matlab/mio.py", line 134, in loadmat
MR = mat_reader_factory(file_name, appendmat, **kwargs)
File "/usr/lib64/python2.7/site-packages/scipy/io/matlab/mio.py", line 58, in mat_reader_factory
mjv, mnv = get_matfile_version(byte_stream)
File "/usr/lib64/python2.7/site-packages/scipy/io/matlab/miobase.py", line 224, in get_matfile_version
raise MatReadError("Mat file appears to be empty")
scipy.io.matlab.miobase.MatReadError: Mat file appears to be empty`

And I noticed that the output .mat file is empty!!!
Also I checked the matlab script worked fine(Actually I don't know whether it's OK or not.):

`[root@localhost selective_search_ijcv_with_python-master]# matlab -nojvm -r "try; selective_search({'/home/philip/Desktop/fast-rcnn/data/demo/selective_search_ijcv_with_python-master/000015.jpg','/home/philip/Desktop/fast-rcnn/data/demo/selective_search_ijcv_with_python-master/cat.jpg','/home/philip/Desktop/fast-rcnn/data/demo/selective_search_ijcv_with_python-master/000015.jpg','/home/philip/Desktop/fast-rcnn/data/demo/selective_search_ijcv_with_python-master/cat.jpg','/home/philip/Desktop/fast-rcnn/data/demo/selective_search_ijcv_with_python-master/000015.jpg','/home/philip/Desktop/fast-rcnn/data/demo/selective_search_ijcv_with_python-master/cat.jpg','/home/philip/Desktop/fast-rcnn/data/demo/selective_search_ijcv_with_python-master/000015.jpg','/home/philip/Desktop/fast-rcnn/data/demo/selective_search_ijcv_with_python-master/cat.jpg'}, '/tmp/tmpaRllSN.mat'); catch; exit; end; exit"
