Description
A fresh .venv built from build_uv_env.sh installs torchaudio 2.11.0 against torch 2.7.0. The ABI mismatch throws OSError: undefined symbol: torch_library_impl on first import, which crashes the very first complexa download.
Severity: High · Status: workaround verified; upstream open
Steps to reproduce
- Build the UV env from scratch (
build_uv_env.sh). - Run
complexa download(or anything importing torch/torchaudio). - →
OSError: undefined symbol: torch_library_impl.
Fix
Pin a compatible torchaudio:
uv pip install --torch-backend=cu126 --reinstall-package torchaudio "torchaudio==2.7.0"
build_uv_env.sh should pin torchaudio==2.7.0.
Environment
- NVIDIA A100 80GB PCIe · driver 565.57.01 · CUDA 12.7
- Repo: branch
dev@916eaae - Runtime: UV (
.venv+env.sh)

Research direction
Start in build_uv_env.sh and reproduce the fresh UV environment setup described in the issue. Pin torchaudio to 2.7.0, then verify that complexa download or a torch/torchaudio import no longer raises the undefined-symbol error.
