REM ACE-Step Gradio Web UI Launcher - AMD ROCm 7.2
REM For AMD RX 7000/6000 series GPUs on Windows 11
REM IMPORTANT: Requires Python 3.12 (AMD ROCm 7.2 only provides Python 3.12 wheels)
REM Requires: ROCm PyTorch from repo.radeon.com

REM ==================== Load .env Configuration ====================
REM Load settings from .env file if it exists
call :LoadEnvFile

REM ==================== ROCm Configuration ====================
REM Force PyTorch LM backend (bypasses nano-vllm flash_attn dependency)
set ACESTEP_LM_BACKEND=pt

REM RDNA3 GPU architecture override (RX 7900 XT/XTX, RX 7800 XT, etc.)
REM Change to 11.0.1 for gfx1101 (RX 7700 XT, RX 7800 XT)
REM Change to 11.0.2 for gfx1102 (RX 7600)
set HSA_OVERRIDE_GFX_VERSION=11.0.0

REM Disable torch.compile Triton backend (not available on ROCm Windows)
set TORCH_COMPILE_BACKEND=eager

REM MIOpen: use fast heuristic kernel selection instead of exhaustive benchmarking
REM Without this, first-run VAE decode hangs for minutes on each conv layer
set MIOPEN_FIND_MODE=FAST

REM HuggingFace tokenizer parallelism
set TOKENIZERS_PARALLELISM=false

REM ==================== Server Configuration ====================

REM You can override these by uncommenting and modifying the lines below
REM or by creating a .env file (recommended to survive updates)

REM Models shuttle between CPU/GPU as needed (DiT stays on GPU, LM/VAE/text_encoder move on demand)
REM Adds ~8-10s overhead per generation but prevents VRAM oversubscription
REM Disable if using 1.7B/0.6B LM or if your GPU has >=24GB VRAM
