Development of a Voice Conversion App: Overcoming Seed-VC Model Download Issues
When developing a voice conversion app, I encountered an issue while trying to download the 44.1kHz Seed-VC model set (DiT weights, rmvpe, and BigVGAN vocoder) using huggingface_hub.
When attempting to download models using huggingface_hub, the transfer would stop halfway through large files (hundreds of MB) and never progress.
While small config.json files would download quickly, larger .pth or .pt files would get stuck at a certain point and freeze. This article describes how to use curl's stagnation detection and automatic resumption to ensure successful downloads, and create a custom Hugging Face cache structure to enable model reading even when HF_HUB_OFFLINE=1.
Symptoms: Only Large Files Freeze Silently
