From cdac5a8b326abb7ee0d71972714f2ef039096c9d Mon Sep 17 00:00:00 2001 From: clsferguson <48876201+clsferguson@users.noreply.github.com> Date: Mon, 22 Sep 2025 09:28:12 -0600 Subject: [PATCH] feat(entrypoint): add comprehensive error handling and RTX 50 series support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enhance entrypoint script with robust error handling, PyTorch validation, and RTX 50 support PyTorch CUDA Validation: - Add test_pytorch_cuda() function to verify CUDA availability and enumerate devices - Display compute capabilities for all detected GPUs during startup - Validate PyTorch installation before attempting Sage Attention builds Enhanced GPU Detection: - Update RTX 50 series architecture targeting to compute capability 12.0 (sm_120) - Improve mixed-generation GPU handling with better compatibility logic - Add comprehensive logging for GPU detection and strategy selection Triton Version Management: - Add intelligent fallback system for Triton installation failures - RTX 50 series: Try latest → pre-release → stable fallback chain - RTX 20 series: Enforce Triton 3.2.0 for compatibility - Enhanced error recovery when specific versions fail Build Error Handling: - Add proper error propagation throughout Sage Attention build process - Implement graceful degradation when builds fail (ComfyUI still starts) - Comprehensive logging for troubleshooting build issues - Better cleanup and recovery from partial build failures Architecture-Specific Optimizations: - Proper TORCH_CUDA_ARCH_LIST targeting for mixed GPU environments - RTX 50 series: Use sm_120 for Blackwell architecture support - Multi-GPU compilation targeting prevents architecture mismatches - Intelligent version selection (v1.0 for RTX 20, v2.2 for modern GPUs) Command Line Integration: - Enhanced argument handling preserves user-provided flags - Automatic --use-sage-attention injection when builds succeed - Support for both default startup and custom user commands - SAGE_ATTENTION_AVAILABLE environment variable for external integration This transforms the entrypoint from a basic startup script into a comprehensive GPU optimization and build management system with enterprise-grade error handling. --- entrypoint.sh | 93 +++++++++++++++++++++++++++++++++++---------------- 1 file changed, 64 insertions(+), 29 deletions(-) diff --git a/entrypoint.sh b/entrypoint.sh index e60a4aaa2..0f92c7dea 100644 --- a/entrypoint.sh +++ b/entrypoint.sh @@ -16,6 +16,24 @@ log() { echo "[$(date '+%H:%M:%S')] $1" } +# Function to test PyTorch CUDA compatibility +test_pytorch_cuda() { + python -c " +import torch +import sys +if not torch.cuda.is_available(): + print('[ERROR] PyTorch CUDA not available') + sys.exit(1) + +device_count = torch.cuda.device_count() +print(f'[TEST] PyTorch CUDA available with {device_count} devices') + +for i in range(device_count): + props = torch.cuda.get_device_properties(i) + print(f'[TEST] GPU {i}: {props.name} (Compute {props.major}.{props.minor})') +" 2>/dev/null +} + # Function to detect all GPUs and their generations detect_gpu_generations() { local gpu_info=$(nvidia-smi --query-gpu=name --format=csv,noheader,nounits 2>/dev/null || echo "") @@ -59,6 +77,13 @@ detect_gpu_generations() { export GPU_COUNT=$gpu_count log "Detection summary: RTX20=$has_rtx20, RTX30=$has_rtx30, RTX40=$has_rtx40, RTX50=$has_rtx50" + + # Test PyTorch CUDA compatibility + if test_pytorch_cuda;
