Download dataset

When I click to download DOTAv1.5.zip, it will automatically stop when it reaches 1.5G. The download log shows that there is a problem with the website.

This appears to be a server or network connectivity issue. Try using the safe_download function from ultralytics which includes retry mechanisms and better error handling:

from ultralytics.utils.downloads import safe_download
safe_download("https://release-assets.githubusercontent.com/github-production-release-asset/521807533/91f6b769-e30f-4bc4-8846-f2fd8def2081?sp=r&sv=2018-11-09&sr=b&spr=https&se=2025-08-08T12%3A54%3A38Z&rscd=attachment%3B+filename%3DDOTAv1.5.zip&rsct=application%2Foctet-stream&skoid=96c2d410-5711-43a1-aedd-ab1947aa7ab0&sktid=398a6654-997b-47e9-b12b-9515b896b4de&skt=2025-08-08T11%3A54%3A07Z&ske=2025-08-08T12%3A54%3A38Z&sks=b&skv=2018-11-09&sig=6C8DfPNiCX6fufVQ5%2F4hbiW0HyngzxYBlAVoYdQLSG4%3D&jwt=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJnaXRodWIuY29tIiwiYXVkIjoicmVsZWFzZS1hc3NldHMuZ2l0aHVidXNlcmNvbnRlbnQuY29tIiwia2V5Ijoia2V5MSIsImV4cCI6MTc1NDY1NTIyMiwibmJmIjoxNzU0NjU0OTIyLCJwYXRoIjoicmVsZWFzZWFzc2V0cHJvZHVjdGlvbi5ibG9iLmNvcmUud2luZG93cy5uZXQifQ.8TIwytDNdm-aOvZdcijuDnM5SBa1MB2-IRYDNSOtbio&response-content-disposition=attachment%3B%20filename%3DDOTAv1.5.zip&response-content-type=application%2Foctet-stream", retry=3)

This approach should handle temporary connection issues more reliably than direct browser downloads.
