The error makes sense but I don't know how to retry the data download
Thanks for reporting, @SaulLu .
This error raises when the source data files are hosted in servers with strong constraints in the allowed request limit:
- One possible solution is to optimize the loading script so that it makes as few as possible filesystem requests. But I have had a look at your code and I think it is already optimized in this sense.
- Therefore, the remaining possible solution is to host their data on the Hub (under a
datadirectory in the same repo) if their license allows so.
Thanks a lot for the quick answer @albertvillanova ! I really appreciate it! I must admit that it's a lot of things to do and check to see if the viewer can work, so for the moment we will do without the viewer.
OK @SaulLu .
Just note that this issues is not exclusive of the viewer, but of streaming. There will be no problem as long as you you do not use the dataset in streaming mode.
If you want to use it in streaming mode, then I think you should host the data files here in this repo as well, so that the error will be fixed.
