A problem about load dataset #4

Closed sherlie831 closed 2 years ago

sherlie831 commented 2 years ago

Hi, I am trying to run ESS, may I ask which sequence of Cityspace is used for training? What is the format of the Cityspace dataset?

I have downloaded leftimg8bit and gtFine from the Cityspace website to solve the above problem.

But the following error occurred when I tried to run train.py: Loading model e2vid/pretrained/E2VID_lightweight.pth.tar... Using TransposedConvLayer (fast, with checkerboard artefacts) Using TransposedConvLayer (fast, with checkerboard artefacts) Cityscapes num of batches: 371 62 Traceback (most recent call last): File "/home/x/code/ESS/train.py", line 57, in <module> main() File "/home/x/code/ESS/train.py", line 38, in main trainer = ESSModel(settings) File "/home/x/code/ESS/training/ess_trainer.py", line 22, in __init__ super(ESSModel, self).__init__(settings) File "/home/x/code/ESS/training/base_trainer.py", line 29, in __init__ self.createDataLoaders() File "/home/x/code/ESS/training/base_trainer.py", line 320, in createDataLoaders self.settings.fixed_duration_b) File "/home/x/code/ESS/training/base_trainer.py", line 173, in createDSECDataset fixed_duration=fixed_duration) File "/home/x/code/ESS/datasets/DSEC_events_loader.py", line 36, in DSECEvents augmentation=augmentation, fixed_duration=fixed_duration, resize=resize) File "/home/x/code/ESS/DSEC/dataset/provider.py", line 45, in __init__ , resize=resize)) File "/home/x/code/ESS/DSEC/dataset/sequence.py", line 109, in __init__ assert img_left_dir.is_dir() AssertionError `

I try to positioning error, I found in the ESS/DSEC/dataset/sequence. py files line 107： if self.require_paired_data: img_dir = seq_path / 'images' img_left_dir = img_dir / 'left' / 'ev_inf' assert img_left_dir.is_dir()

The code runs here to load images from test/zurich_city_13_a/images, and DSEC-Semantic does not have this folder, so what images are being loaded here?

Hi @sherlie831, sorry to bother you! Have you solved this problem? What does ev_inf mean here?
