Overview

Repository contains the code for 2nd place solution of VinBigData Chest X-ray Abnormalities Detection competition. The goal of competition was to automatically localize and classify thoracic abnormalities from chest radiographs.

Kaggle forum posts about the solution:

Details

Solution consists of 3 parts. Each part is models from each team member. Predictions of each part in the end ensembled in single 2nd place submission on LeaderBoard. You can use only inference or train models from scratch.

Warning: since some of the data is hosted on Kaggle, in order to be able to download it, save your Kaggle API token to .kaggle/kaggle.json

  • Question to sergey part, 640 or 1024 size?

    Question to sergey part, 640 or 1024 size?

    Question to Sergey Part, why he first resizes to 640 for inference, but then normalizes the resultant boxes like they were for 1024*1024 pixels image?

    pred_boxes, pred_scores, pred_labels = predict_for_files(weights, folder, imagenames, 640, is_TTA)
....
if len(cur_boxes) > 0:
    cur_boxes[:, [0, 2]] = (cur_boxes[:, [0, 2]] * image_width / 1024).astype(int)
    cur_boxes[:, [1, 3]] = (cur_boxes[:, [1, 3]] * image_height / 1024).astype(int)

    Regarding Learning Rate

    Regarding ivan part on mmdetection Can you please upload schedule_1x.py. The below error is seen. There was another solution recommended in (https://github.com/open-mmlab/mmdetection/issues/6456) Can you confirm on the same.

    Traceback (most recent call last): File "/home/prashant/anaconda3/envs/kmmdet/lib/python3.7/site-packages/mmcv/utils/registry.py", line 52, in build_from_cfg return obj_cls(**args) File "/home/prashant/anaconda3/envs/kmmdet/lib/python3.7/site-packages/mmcv/runner/hooks/lr_updater.py", line 264, in init super(CosineAnnealingLrUpdaterHook, self).init(**kwargs) TypeError: init() got an unexpected keyword argument 'step'

    No hyper-parameter yaml found

    Thanks for sharing your great work.

    I was trying to run the training code for yolov5, but then it gives me an error saying "AssertionError: File Not Found: data/hyp.scratch.yaml"

    I can not find any scrip that generates hyp.scratch.yaml.

    Am I missing something?

    Thanks, Joseph

    No MegaMix 341_healthy file

    Hello! Again question about Sergey part) After inference, postprocess.py requires "../MegaMix/341_healthy.csv" file, can you please say where I can download it and why it is needed? Блин чет забыл что авторы русские и написал на английском вопрос опять)
