Thanks for the report! I'm not sure exactly why this is happening but some extra information would help. Would you mind building tippecanoe from https://github.com/felt/tippecanoe/pull/220, rerunning your tiling, and sending me the extra log output that you get? On my laptop I get:
Using 32 temporary files and 1 threads on 8 CPUS for 32 child shards
Using 32 temporary files and 4 threads on 8 CPUS for 8 child shards
Using 32 temporary files and 8 threads on 8 CPUS for 4 child shards
Using 32 temporary files and 8 threads on 8 CPUS for 4 child shards
Using 32 temporary files and 8 threads on 8 CPUS for 4 child shards
Using 32 temporary files and 8 threads on 8 CPUS for 4 child shards
but there must be a miscalculation somewhere based on how many CPUs your computer has and how many files it allows open at once.
Thanks for your reply! Unfortunately, I wasn't able to build it successfully and ran into a couple of errors in the process. However, for context, Tippecanoe is running on a Kubernetes node which means it has access to shared CPU which is quite large. With the way Kubernetes works, I don't think the size of the CPU is also going to be guaranteed a power of 2 which would explain the error. I'll keep trying to build it and comment again if I can get that extra logging.
When trying to convert my GeoJSONs to tiles, I get the error
Internal error: 745 shards not a power of 2
.My tiles end up empty at only 28kb. I'm using Tippecanoe with Ubuntu on Docker. I haven't gotten this issue before but it's suddenly coming up even though nothing has changed with my installation. I'm calling Tippecanoe from Python subprocess using the command below:
Not sure where to go from here and there doesn't seem to be much online about this issue, any tips on debugging?
