@Nic-Ma @wyli, this PR is ready to be reviewed/merged. Thanks

As I mentioned in #308, this notebook now tries to download two large histopathology images. Although the runner should work but it might take a while depending on the server speed (about 1 hour). Do you want me to exclude it from runner.sh again or it's fine since it is a cron job?

Hi @wyli ,

I feel 1 hour is acceptable for cron job, but it should be stable enough.
What do you think?

Thanks.

I saw that the cron job has 150min timeout for all the notebook. I'll move things to our google drive (instead of outside ftp) to speed up the download, and will change this notebook accordingly.

@Nic-Ma @wyli,
I updated the notebook and now it's only doing profiling for training (not validation) and only with the smallest Camelyon tumor image. I moved the image to our google drive and now it's very fast to download and depending on internet speed it should take more than few minutes.

I don't have write access to this repo so can any of you merge it. Thanks

[wyli]

Thanks for enhancing the tests!
