Overview

TGS Salt Identification Challenge

This is an open solution to the TGS Salt Identification Challenge.

Note

Unfortunately, we can no longer provide support for this repo. Hopefully, it should still work, but if it doesn't, we cannot really help.

More competitions 🎇

Check collection of public projects 🎁 , where you can find multiple Kaggle competitions with code, experiments and outputs.

Our goals

We are building entirely open solution to this competition. Specifically:

Learning from the process - updates about new ideas, code and experiments is the best way to learn data science. Our activity is especially useful for people who wants to enter the competition, but lack appropriate experience.
Encourage more Kagglers to start working on this competition.
Deliver open source solution with no strings attached. Code is available on our GitHub repository 💻 . This solution should establish solid benchmark, as well as provide good base for your custom ideas and experiments. We care about clean code 😃
We are opening our experiments as well: everybody can have live preview on our experiments, parameters, code, etc. Check: TGS Salt Identification Challenge 📈 or screen below.

Train and validation monitor 📊

Disclaimer

In this open source solution you will find references to the neptune.ai. It is free platform for community Users, which we use daily to keep track of our experiments. Please note that using neptune.ai is not necessary to proceed with this solution. You may run it as plain Python script 🐍 .

Start experimenting with ready-to-use code

You can jump start your participation in the competition by using our starter pack. Installation instruction below will guide you through the setup.

Installation

Clone repository

git clone https://github.com/minerva-ml/open-solution-salt-identification.git

Set-up environment

You can setup the project with default env variables and open NEPTUNE_API_TOKEN by running:

source Makefile

I suggest at least reading the step-by-step instructions to know what is happening.

Install conda environment salt

conda env create -f environment.yml

After it is installed you can activate/deactivate it by running:

conda activate salt

conda deactivate

Register to the neptune.ai (if you wish to use it) even if you don't register you can still see your experiment in Neptune. Just go to shared/showroom project and find it.

Set environment variables NEPTUNE_API_TOKEN and CONFIG_PATH.

If you are using the default neptune.yaml config then run:

export export CONFIG_PATH=neptune.yaml

otherwise you can change to your config.

Registered in Neptune:

Set NEPTUNE_API_TOKEN variable with your personal token:

export NEPTUNE_API_TOKEN=your_account_token

Create new project in Neptune and go to your config file (neptune.yaml) and change project name:

project: USER_NAME/PROJECT_NAME

Not registered in Neptune:

open token

export NEPTUNE_API_TOKEN=eyJhcGlfYWRkcmVzcyI6Imh0dHBzOi8vdWkubmVwdHVuZS5tbCIsImFwaV9rZXkiOiJiNzA2YmM4Zi03NmY5LTRjMmUtOTM5ZC00YmEwMzZmOTMyZTQifQ==

Create data folder structure and set data paths in your config file (`neptune.yaml`)

Suggested directory structure:

project
|--   README.md
|-- ...
|-- data
    |-- raw
         |-- train 
            |-- images 
            |-- masks
         |-- test 
            |-- images
         |-- train.csv
         |-- sample_submission.csv
    |-- meta
        │-- depths.csv
        │-- metadata.csv # this is generated
        │-- auxiliary_metadata.csv # this is generated
    |-- stacking_data
        |-- out_of_folds_predictions # put oof predictions for multiple models/pipelines here
    |-- experiments
        |-- baseline # this is where your experiment files will be dumped
            |-- checkpoints # neural network checkpoints
            |-- transformers # serialized transformers after fitting
            |-- outputs # outputs of transformers if you specified save_output=True anywhere
            |-- out_of_fold_train_predictions.pkl # oof predictions on train
            |-- out_of_fold_test_predictions.pkl # oof predictions on test
            |-- submission.csv
        |-- empty_non_empty 
        |-- new_idea_exp

in neptune.yaml config file change data paths if you decide on a different structure:

  # Data Paths
  train_images_dir: data/raw/train
  test_images_dir: data/raw/test
  metadata_filepath: data/meta/metadata.csv
  depths_filepath: data/meta/depths.csv
  auxiliary_metadata_filepath: data/meta/auxiliary_metadata.csv
  stacking_data_dir: data/stacking_data

Run experiment based on U-Net:

Prepare metadata:

python prepare_metadata.py

Training and inference. Everything happens in main.py. Whenever you try new idea make sure to change the name of the experiment:

EXPERIMENT_NAME = 'baseline'

to a new name.

python main.py

You can always change the pipeline you want ot run in the main. For example, if I want to run just training and evaluation I can change `main.py':

if __name__ == '__main__':
    train_evaluate_cv()

Conflicts between open-solution-salt-identification and ipython

Hi, users are unable to run open-solution-salt-identification due to dependency conflict with ipython package. As shown in the following full dependency graph of open-solution-salt-identification, open-solution-salt-identification requires ipython==6.3.1, while steppy==0.1.6 requires _ipython >= 6.4.0. According to pip’s “first found wins” installation strategy, ipython 6.3.1 is the actually installed version. However, ipython 6.3.1 does not satisfy >=6.4.0.

Installation fails due to another conflicting pandas version

Hi, another dependency hell issue in open-solution-salt-identification. Users are unable to run open-solution-salt-identification due to dependency conflict with pandas package. As shown in the following full dependency graph of open-solution-salt-identification, this project directly requires pandas==0.22.0，while steppy-toolkit==0.1.5 requires _pandas>=0.23.0. According to pip’s “first found wins” installation strategy, pandas==0.22.0 is the actually installed version. However, pandas==0.22.0 does not satisfy >=0.23.0.

Solution

Relax the version range of pandas (change pandas==0.22.0 to >=0.22.0).

SO suggest to convert list to numpy this way np.asarray(coff) * C

but actually I'm kind confused where to apply it

Can not find the 'metadata.csv'

When I run the command 'python main.py -- train--pipeline_name unet', I got the error "Can not find the 'metadata.csv'" . I checked all the files of salt-detection and still can not find it. Did I miss something important?

Lovasz loss

Hi,

Thank you for the code. I am attempting to run your code with the lovasz hinge loss, and run into the following error -- please let me know if there is a quick way to fix this.

File "..../lovash_losses.py", line 105, in lovasz_hinge_flat errors = (1. - logits * Variable(signs)) RuntimeError: Variable data has to be a tensor, but got Variable

Apologies if this is a simple question -- recently converted from Keras, so not that familiar with Torch.

Memory Allocation of Solution 4

Hi~ Thanks for your team's great work. I implemented the solution 4 in a local machine. However, I found something quite annoying in the loop of cross-validation. Here are 2 pictures about the memory problem: The first one is the statistics of memory using during the fold_0. The second one is "fold_1". It is obvious that it will cost 3GB RAM after each training processing: I started this training process last night and went to bed. I saw the error of "cannot allocate memory" this morning. Can u give me some tip so how to solve this problem?

Confusion Matrix

As per the discussions on Kaggle, yours implementation is the only implementation that is fully correct for the given metric but there is one thing that I couldn't understand as per your code. Here are these three functions:

def compute_ious(gt, predictions):
    gt_ = get_segmentations(gt)
    predictions_ = get_segmentations(predictions)

    if len(gt_) == 0 and len(predictions_) == 0:
        return np.ones((1, 1))
    elif len(gt_) != 0 and len(predictions_) == 0:
        return np.zeros((1, 1))
    else:
        iscrowd = [0 for _ in predictions_]
        ious = cocomask.iou(gt_, predictions_, iscrowd)
        if not np.array(ious).size:
            ious = np.zeros((1, 1))
        return ious


def compute_precision_at(ious, threshold):
    mx1 = np.max(ious, axis=0)
    mx2 = np.max(ious, axis=1)
    tp = np.sum(mx2 >= threshold)
    fp = np.sum(mx2 < threshold)
    fn = np.sum(mx1 < threshold)
    return float(tp) / (tp + fp + fn)

def compute_eval_metric(gt, predictions):
    thresholds = [0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95]
    ious = compute_ious(gt, predictions)
    precisions = [compute_precision_at(ious, th) for th in thresholds]
    return sum(precisions) / len(precisions)

Now, given the fact that compute_ious function works on a single prediction and it's corresponding groundtruth, ious will be a singleton array. Then, how are you calculating TP/FP from that? Am I missing something here?

GPU utilization is 0 most of the time

nvidia-smi gives 0% percentage GPU-Util most of the time(in offline mode). Am I doing something wrong? Using the same config file as in [solution-3]. CPU usage is high most of the time.
