Many unclear errors when running main.py -- prepare_masks #179

Closed carbonox-infernox closed 5 years ago

carbonox-infernox commented 5 years ago

Using Ubuntu 16.04 and Python 3.6

I'm running the command: python main.py -- prepare_masks and getting the following error:

neptune: Executing in Offline Mode. neptune: Executing in Offline Mode. 2018-09-18 09-15-04 mapping-challenge >>> Overlaying masks, dataset: train 2018-09-18 09-15-04 mapping-challenge >>> Output directory: ~/open-solution-mapping-challenge/data/masks_overlayed_eroded_0_dilated_2 loading annotations into memory...

I've checked many times that annotation.json is in the right directory, and i also tried re-extracting it. @taraspiotr suggested preparing the metadata first but it doesn't matter which order I run the commands in. I have a stage1_metadata.csv but it is empty.

I think I fixed the issue by replacing ~/ in the file path with the full home/username. At least, it started trying to actually work but then it overwhelmed my system's resources with the number of files.
