Food Recognition Challenge
Submission problem, can't start evaluation issue
Almost 4 years agoI tried just now as well, and have the same issue @shivam
Train using mmdetection and submit via Colab (Round 2)!
Over 4 years agoHey,
I think the baseline(food-round2) was created using this config file. You can compare this with the config you are using right now and try find out where the issue might be.
Cannot upload to the git even git lfs is checked ... windows using git tortoise
Over 4 years agoNot unless it would be something compute intensive. Have you managed to get your code running locally using nvdia-docker, if your code works locally on nvidia-docker then maybe it is a server issue.
Step by step tutorials
Over 4 years agoI’m not quite sure what errors you ran into while changing the model, I’ve made a notebook that does exactly that and makes a submission directly on colab. You can check it out here Train using mmdetection and submit via Colab!

Cannot upload to the git even git lfs is checked ... windows using git tortoise
Over 4 years agoClearly for some reason the module has not been installed in your docker image. I would suggest adding RUN pip install scikit-image in your Dockerfile. Since this is a docker issue, I think you could find the problem by debugging locally. It is explained in the baseline repo’s readme.
It seems you have a submission in progress already, I hope you’ve managed to solve your issue.
Train using mmdetection and submit via Colab (Round 2)!
Over 4 years agoLEARN HOW TO SUBMIT | NO SSH | ON COLAB | DIRECTLY!!!
Hey everyone,
Since a lot of people seem to be finding it difficult to submit, we’ve converted the baseline code using mmdetection into a colab notebook which allows you to submit directly via colab. If you are not using mmdetection you can still check this notebook out and have a look at the submission steps. If you have any issues or need any help do feel free to post here.

New Starter Notebook + paperspace
Over 4 years agoHey everyone,
We know that computing resources may be really difficult to come by, especially for beginners, so we have written a new starter notebook that allows you to train a MaskRCNN model directly on Colab.
This dataset and notebook correspond to the Food Recognition Challenge being held on AICrowd.
In this Notebook, we will first do an analysis of the Food Recognition Dataset and then use maskrcnn for training on the dataset.
The Challenge¶
- Given Images of Food, we are asked to provide Instance Segmentation over the images for the food items.
- The Training Data is provided in the COCO format, making it simpler to load with pre-available COCO data processors in popular libraries.
- The test set provided in the public dataset is similar to Validation set, but with no annotations.
- The test set after submission is much larger and contains private images upon which every submission is evaluated.
- Pariticipants have to submit their trained model along with trained weights. Immediately after the submission the AICrowd Grader picks up the submitted model and produces inference on the private test set using Cloud GPUs.
- This requires Users to structure their repositories and follow a provided paradigm for submission.
- The AICrowd AutoGrader picks up the Dockerfile provided with the repository, builds it and then mounts the tests folder in the container. Once inference is made, the final results are checked with the ground truth.
For more submission related information, please check the AIcrowd Challenge page and the starter kit.
The Notebook¶
- Installation of MaskRCNN
- Using MatterPort MaskRCNN Library and Making local inference with it
- Local Evaluation Using Matterport MaskRCNN
A bonus section on other resources to read is also added!

MaskRCNN¶
To train MaskRCNN, two things we have to define FoodChallengeDataset that implements the Dataset class of MaskRCNN and FoodChallengeConfig that implements the Config class.
The FoodChallengeDataset helps define certain functions that allow us to load the data.
The FoodChallengeConfig gives the information like NUM_CLASSES, BACKBONE, etc.

This, in addition to the existing Mask RCNN baseline repo should allow you to plug and play models for easy submission and experimentation.
As an alternative to Colab, Paperspace is an amazing option. Their gradient community notebooks let you use free cloud GPU’s and CPU’s and also provide internal storage that let you save models and resume training after the deployment time expires.

Cannot upload to the git even git lfs is checked ... windows using git tortoise
Over 4 years agohave you setup git-lfs properly? These are the steps I used:
(check that git-lfs is setup correctly in your git configuration files)
git lfs install
track the model files, if the models are saved as model.pth for example, use the following to track all pth files
git lfs track '*.pth'
Next, you need to add .gitattributes to your git repository.
git add .gitattributes
Now that this is all set up, you should be able add the model to the git repo by
git add .
git commit -m "commit message"
git push -u origin master
Let me know if this helped.

Where to submit the repository link?
Over 4 years agoTo submit you’ll need to create a private git repository at https://gitlab.aicrowd.com with the contents of your submission(this is where all your files need to be,along with the appropriate directory structure mentioned in the starter-kit readme), and push a git tag corresponding to the version of your repository you’d like to submit.
The starter-kit has more instructions on how you can submit. Hope this helped.

Learning to Smell
Where to start? 5 ways to learn 2 smell!
About 4 years agoHi everyone!
@rohitmidha23 and me are undergrad students studying computer science, and found this challenge particularly interesting to explore the applications of ML in Chemistry. We have written a notebook that explores 5 ways to attempt this challenge. It includes baselines for
- ChemBERTa
- Graph Conv Networks
- MultiTaskClassifier using Molecular Fingerprints
- Sklearn Classifiers (Random Forest etc.) using Molecular Fingerprints
- Chemception (2D representation of molecules)
Check it out @ https://colab.research.google.com/drive/1-RedHEQSAVKUowOx2p-QoKthxayRshUa?usp=sharing
The most difficult task in this challenge is trying to get good representations of SMILES that is understandable for ML algorithms and we have tried to give examples on how that has been done in the past for these kind of tasks.
We hope that this notebook helps out other beginners like ourselves.
As always we are open to any feedback, suggestions and criticism!

The title is self-explanatory. Nothing too major, just some visualizations and a baseline model that we hope can help all those looking to start out.
Some really cool 3D visualizations for you to interact and play around with. Geologists in the community, looking to you to make more sense of the data and maybe even share some insights before the challenge ends

Hockey Team Classification
Request to see individual submission scores
About 4 years agoHey @jason_brumwell,
Would it be possible to see the score of each submission? Currently, we can only see the submission that scored the highest on the leaderboard. This would really help understand how different approaches work for this task. Would this be possible? or is there a specific reason for not showing the scores?

FOODC
Image ambiguity
Over 4 years agoHi @jakub_bartczuk,
Thanks for your observations and feedback. The images in this dataset were collected from real users who track their daily food habits by taking pictures of food items they consume, and hence reflects the actual distribution of the data in the wild !
As you would expect there would be a few overlapping food items as well as some level of wrongly annotated data. Having gone through the data myself, there is a significant portion of images that can be classified as just one thing. There definitely are some exceptions as you have found. For example here is a visualization of all the images in the hard cheese class.
Some of the images have multiple food items, and hence as pointed out by you, there is significant merit in treating this as a multi-label classification problem. As a matter of fact, we plan to release a much larger version of this dataset with individual segmentations of all the different food items in each of the images, modelled as an image segmentation task. The said task would be a research challenge and not a part of the educational Blitz related initiatives. But we assure you, the nuanced data distributions and class imbalances will continue to be well represented even in the larger dataset : because it is what the real world distribution is.
At the same time, as mentioned in the forums a few times, we wanted to come up with a simplified classification problem from the original dataset as an easy-to-get-started problem for many of the community members.
We appreciate your inputs and the points you raised around the problem formulation, and are sure all of them would be well addressed when the larger dataset is released at the end of this month.
As this iteration of the AIcrowd Blitz ends, we hope we will be successful in aggregating all the activity that happened around these starter problems, and hope that we will be able to have continued engagement from community members like yourself even in the research challenges that we will organize as extensions to these problems.
Regards

@rohitmidha23 and me have been following this challenge for quite a while. We have written a starter notebook using MaskRCNN. We further integrate MaskRCNN with WandB which really helps to keep track of the various experiments that anyone might want to run. Check out our runs here
We also added functionality to view predictions of the model on the validation set as the model trains.
You can find the notebook @ https://colab.research.google.com/drive/1D8jC9GdHhCyoGB-8bJogW-lSO21MeTKF?usp=sharing
We trained the model on 40 classes alone due to Colab’s timing restrictions. However we provide a GitHub repo using which you can train on the entire dataset.
We also made a submission repo, using which you can submit models trained using the code above. The model we trained gets a precision score of 0.135 on the test set.
We hope that this notebook helps out other participants.
As always we are open to any feedback, suggestions and criticism!
