label-maker-dask.ipynb example tutorial fails

[benmack]

The https://github.com/microsoft/PlanetaryComputerExamples/blob/main/tutorials/label-maker-dask.ipynb tutorial fails for me.

When running lmj.execute_job() I get many repetition of the following warning:

distributed.worker - WARNING - Compute Failed

args:      ((<function tile_to_label at 0x7f6dd4e45c10>, Tile(x=15550, y=12548, z=15), 'segmentation', [(<class 'dict'>, [['name', 'Roads'], ['filter', ['has', 'highway']]]), (<class 'dict'>, [['name', 'Buildings'], ['filter', ['has', 'building']]])], '[https://qa-tiles-server-dev.ds.io/services/z17/tiles/{z}/{x}/{y}.pbf](https://qa-tiles-server-dev.ds.io/services/z17/tiles/%7Bz%7D/%7Bx%7D/%7By%7D.pbf)'))

Followed by an SSL error

Looks like the label_source does not work as suggested in the notebook.

• label_source: str. A template string for a tile server providing OpenStreetMap QA tiles. Planetary Computer hosts a tile server supporting this format at https://qa-tiles-server-dev.ds.io/services/z17/tiles/{z}/{x}/{y}.pbf

cc @drewbo. Do you have any insight into the qa-tiles-server-dev.ds.io tile server?

[drewbo]

Hi @TomAugspurger, sorry I don't have insight into the state of that server (I've transitioned to a new role). cc: @geohacker @batpad for more info

[geohacker]

Thanks for the ping @drewbo! @TomAugspurger I'm not sure what the state of that server is, sorry! We noticed this on PEARL as well and I assumed that you guys must have cleaned it up those dev stacks. I think I may have also lost access to the PC devops account.

If the stack wasn't deleted, is it possible for you to paste the logs here? In the meantime, let me try and get access to my devops account.

Update: I tried to login to Azure Devops but got a 401 😭
