【TST在windows10上运行错误】RuntimeError: CUDA out of memory.
系统环境及依赖包
os : Windows-10-10.0.19042-SP0
python : 3.8.12
tsai : 0.2.24
fastai : 2.5.3
fastcore : 1.3.27
torch : 1.10.1
n_cpus : 8
device : cuda (NVIDIA GeForce MX150)
使用TST模型训练时会出现以下错误
RuntimeError: CUDA out of memory. Tried to allocate 764.00 MiB (GPU 0; 2.00 GiB total capacity; 841.93 MiB already allocated; 277.44 MiB free; 854.00 MiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF
原因及解决方法如下
- 减小模型训练的batch_size
- kill 占用GPU内存的进程
- 增加语句，清除缓存
- 设置 max_split_size_mb
设置环境变量PYTORCH_CUDA_ALLOC_CONF为max_split_size_mb:128
