为什么main的新版本，我开启训练后只能使用CPU，没法使用GPU，训练速度低到 0.08setp/s

为什么main的新版本，我开启训练后只能使用CPU，没法使用GPU，训练速度低到 0.08setp/s

{| Epoch: 52/3334 (3/3) | Loss: 1.005 | 0.081 steps/s | Step: 0k | }
{| Epoch: 53/3334 (3/3) | Loss: 0.9955 | 0.081 steps/s | Step: 0k | }
{| Epoch: 54/3334 (3/3) | Loss: 0.9905 | 0.081 steps/s | Step: 0k | }
{| Epoch: 55/3334 (3/3) | Loss: 0.9797 | 0.081 steps/s | Step: 0k | }

任务管理器中，GPU显示为3%，CPU为60%

是还需要修改什么参数吗

Start by reproducing the reported main-version training run and inspect its GPU/CPU selection and training parameters; compare the reported Task Manager utilization and 0.081 steps/s. Done means identifying whether a parameter or environment issue prevents GPU use and documenting the required setting.
