Getting Started with Age Prediction

In this puzzle, we have to predict the age from the given human faces.

This is a starter kit explaining how to download the data and also submit direcly via this notebook.

We will be the sample submission file directly in the required format.

Download the files 💾¶

Download AIcrowd CLI

We will first install aicrowd-cli which will help you download and later make submission directly via the notebook.

In [ ]:
!pip install aicrowd-cli
%load_ext aicrowd.magic

Generating Prediction File

In this starter kit we will directly be submitting the sample prediction file. In case you would like to see a submission via baseline model, check it out here.

In [ ]:
submission = pd.read_csv('data/sample_submission.csv')
In [ ]:
!rm -rf assets
!mkdir assets
submission.to_csv(os.path.join("assets", "submission.csv"))
