4. 监控CUDA内存使用情况 在训练期间,监控内存使用情况非常重要,可以通过以下方法实现: # 显示当前已分配和总内存allocated_memory=torch.cuda.memory_allocated()reserved_memory=torch.cuda.memory_reserved()print(f"已分配内存:{allocated_memory/(1024**2)}MB")print(f"总预留内存:{reserved_memory/(1024**2)...

在训练模型时,我遇到了以下问题: RuntimeError: CUDA out of memory. Tried to allocate 304.00 MiB (GPU 0; 8.00 GiB total capacity; 142.76 MiB already allocated; 6.32 GiB free; 158.00 MiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb ...
在PyTorch中,显存是指显卡内存,用于存储训练过程中的张量和模型参数。在进行显存分析时,我们需要关注以下几个方面: 显存使用量:PyTorch会根据需要自动分配显存,但可能出现显存不足的情况。我们可以使用torch.cuda.memory_allocated()查看当前已分配的显存数量,以及使用torch.cuda.max_memory()查看显卡最多能分配的显存...
🚀 Feature Having multiple resettable torch.cuda.max_memory_allocated() counters Motivation With the help of torch.cuda's reset_max_memory_allocated and max_memory_allocated one can now measure peak memory usage. Which is very helpful. No...
