Installation Instructions Enhancement

[thomasklau]

Hi,

Thanks so much for putting this script together. It's really helpful.

It almost works right out of the box. It would be good to explain explicitly that the user has to install pdollar's MATLAB toolbox in order to use this library. https://pdollar.github.io/toolbox/

Was scratching my head a bit until tried to run your wrapper in MATLAB and saw that functions were being called from the toolbox that wasn't installed.

Hi. I runned the python code, why the mat file is empty?

Hi,

I would need a bit more information on your concrete setup. Usually, an empty mat file would suggest an error has occurred while running the toolbox. And you need the toolbox, regardless of the system type.

Best,

d

One basic question, do we still need matlab installed to use this library?

Hi @thomasklau , I tried to run the python code, but failed: Traceback (most recent call last): File "/home/wqq/External/Data/IDE/pycharm-community-2016.3.2/helpers/pydev/pydevd.py", line 1596, in globals = debugger.run(setup['file'], None, None, is_module) File "/home/wqq/External/Data/IDE/pycharm-community-2016.3.2/helpers/pydev/pydevd.py", line 974, in run pydev_imports.execfile(file, globals, locals) # execute the script File "/home/wqq/DeepLearning/edge_boxes_with_python-master/edge_boxes.py", line 66, in boxes = get_windows(image_filenames) File "/home/wqq/DeepLearning/edge_boxes_with_python-master/edge_boxes.py", line 36, in get_windows shlex.split(mc), stdout=open('/dev/null', 'w'), cwd=script_dirname) File "/home/wqq/anaconda2/lib/python2.7/subprocess.py", line 390, in init errread, errwrite) File "/home/wqq/anaconda2/lib/python2.7/subprocess.py", line 1024, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory

could you provide more information on your installation steps? Thank you very much.

Hi, I install the toolbox and compile the mex file. But when i run the example by python edge_boxes.py I got this error saying mat file empty. edge_boxes_wrapper({'/home/hollyemotion/workspace/edge_boxes_with_python/000004.jpg','/home/hollyemotion/workspace/edge_boxes_with_python/001551.jpg'}, '/tmp/tmpyCbS4U.mat') Traceback (most recent call last): File "edge_boxes.py", line 67, in boxes = get_windows(image_filenames) File "edge_boxes.py", line 42, in get_windows all_boxes = list(scipy.io.loadmat(output_filename)['all_boxes'][0]) File "/usr/local/lib/python2.7/dist-packages/scipy/io/matlab/mio.py", line 135, in loadmat MR = mat_reader_factory(file_name, appendmat, **kwargs) File "/usr/local/lib/python2.7/dist-packages/scipy/io/matlab/mio.py", line 59, in mat_reader_factory mjv, mnv = get_matfile_version(byte_stream) File "/usr/local/lib/python2.7/dist-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

I had the same problem I am using Windows10 with MATLAB2016

Hi. I runned the python code, why the mat file is empty?

Hello. Can you teach me how to edge-boxes all pictures?

Do you handle it? And generate mat files containing boxes and boxscores. Thank you!

Hello, We also had the same problem where the generated mat file is empty. Would appreciate any help with solving this problem, been stuck with it a week now :( Thanks in advance.
