I uploaded a submission.csv to Kaggle APTOS. During training of revised version, I found the training process is kind of slow. So I was thinking using Google TPU which I used for 2 days in the first semester to accelerate the process. And I can use kaggle to commit or submit file and Google TPU to train to avoid waiting time.
Today I spent 1 hour to get myself familiar with TPU. Following resources are useful.
