Missing files in CityScapes dataset #1

Closed Ali2500 closed 5 years ago

After setting up everything according to SETUP.md and running the inference test on validation data from CityScapes, I get the following error:

Traceback (most recent call last): File "eval.py", line 76, in evaluate(evalConfig, model, valLoader) File "/globalwork/athar/person-motion-prediction/instpred/evaluation_functions.py", line 148, in evaluate for i, data in enumerate(val_loader): File "/globalwork/athar/person-motion-prediction/instpred/data_multiscale.py", line 38, in next sample = self.data_source[self.current] File "/home/athar/anaconda2/envs/fb_instpred/lib/python2.7/site-packages/torchnet/dataset/batchdataset.py", line 101, in getitem sample = self.dataset[j] File "/home/athar/anaconda2/envs/fb_instpred/lib/python2.7/site-packages/torchnet/dataset/transformdataset.py", line 46, in getitem z = self.dataset[idx] File "/globalwork/athar/person-motion-prediction/instpred/cityscapesDatasetAndFeatures.py", line 240, in getitem seq = self._add_rgb_bgr_features(sample, seqIDs) File "/globalwork/athar/person-motion-prediction/instpred/cityscapesDatasetAndFeatures.py", line 266, in _add_rgb_bgr_features seq = [np.expand_dims(cv2imread_like(imgID), 0) for imgID in seqIDs] #-- tested to be the same...

Running inference for the image file /work/athar/datasets/Cityscape/leftImg8bit_trainvaltest/leftImg8bit/val/frankfurt/frankfurt_000001_014565_leftImg8bit.png requires a past sequence of frame images (namely, for this case, 014547, 014550, 014553, 014556, 014559, 014562, 014565), but it seems that aside from the last image, none of the others exist in the CityScape dataset.

Although not verified, I think this problem will occur on all the images in the CityScape validation set.

Turns out I'm using the wrong portion of the dataset: the publicly available leftImg8bit_trainvaltest.zip archive does not have the aforementioned frames. The leftImg8bit_sequence_trainvaltest.zip archive has to be used instead.
