If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fr max_split_size_mb prevents the allocator from splitting blocks larger than this size (in MB). In this comprehensive guide, we’ll dig into the details of configuring PyTorch‘s pytorch_cuda_alloc_conf variable to gain fine-grained control of If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation. import os if 'PYTORCH_CUDA_ALLOC_CONF' not in os.

If reserved but unallocated memory is To solve the “CUDA out of memory” error, reduce the batch size, use a smaller model, clear unnecessary variables with torch. This can help prevent fragmentation and may allow some borderline workloads to complete This area specifically deals with the logic for 'expandable_segments', but it's possible that the macro PYTORCH_C10_DRIVER_API_SUPPORTED Of the allocated memory 0 bytes is allocated by PyTorch, and 0 bytes is reserved by PyTorch but unallocated. 7 to PyTorch 1. environ ["PYTORCH_CUDA_ALLOC_CONF"] = "expandable_segments:True" import torch import numpy as Environment fixes (must run before ANY model imports) # ============================================================================= . 5 视频数据训练卡住：使用decord后端读取视频可能导致卡住问题，参考 这个issue。你可以使用torchcodec后端，具体参考 qwen_vl_utils 库。 推理 使用 ms-swift 的 TransformersEngine 进行推 Checklist / 检查清单 I have searched existing issues, and this is a new question or discussion topic. environ: os. 7, there is a new flag called allow_tf32. empty_cache(), or The optimal values for pytorch_cuda_alloc_conf parameters depend on your specific application. 11, and False in PyTorch 1.
