HTTP Error 404 when runing the demo

afalaize commented 5 years ago

Hi! We tried the demo in examples, and got line 48 of dataset.py in download: urllib.error.HTTPError: HTTP Error 404: Not Found This appens after the file data.zip is successfully downloaded.

Unfortunately, the dataloader has a few errors. The 404 Not Found error is due to an incorrect url for downloading the .mat file. Updating as such will fix the error:

downloads = [{'test': False, 'url': 'http://www.vision.ee.ethz.ch/~zzhiwu/codes/AFEW_SPD_data.zip',
              'dst': './data/AFEW', 'zip': True, 'filename': 'data.zip'},
             {'test': False, 'url': 'https://github.com/zzhiwu/SPDNet/raw/master/data/afew/spddb_afew_train_spd400_int_histeq.mat',
              'dst': './data/AFEW', 'zip': False, 'filename': 'spddb_afew_train_spd400_int_histeq.mat'}
             ]

Another error I noticed was FileNotFound when attempting to load batches during training, as the dataloader uses an incorrect path to get items. As the zip file extracts data to ./data/AFEW/spdface_400_inter_histeq/ folder and not ./data/AFEW/, updating the data_path variable in AFEWDataset class' __getitem__ function as such will fix this:

data_path = os.path.join(self.base_path+'/spdface_400_inter_histeq', self.spd_path[index])

Thank you @raj-shah for your contribution. I'll fix them.
