📚 The doc issue As mmcv.runner has been transfered to mmengine, ann there is no force_fp32 in mmengine.runner, how can I get it? Suggest a potential alternative/fix No response
5. (可选) 如果对应某些 OP 希望强制运行在 FP32 上,则可以在对应位置引入 force_fp32 装饰器 # 1 作用到 forward 函数中class ExampleModule(nn.Module):@auto_fp16()def forward(self, x, y):return x, y# 2 如果开启 AMP,则需要加入开启标志model.fp16_enabled = True# 3 配置 Fp16OptimizerHoo...

loss 乘 scale factor s 反向传播(FP16 的模型参数和参数梯度), 此时 gradients 也是 FP16 参数梯度乘 1/s 利用FP16 的梯度更新 FP32 的模型参数 GradientCumulativeOptimizerHook 用于节省显存,即通过指定梯度累积的次数,实现反向传播多次才更新参数,常常用于显存不足但想用比较大的 batch size 训练模型。 Fp16O...

在训练的不同时刻,调用 Fp16OptimizerHook,如果你同时使用了 MMCV 中的 Runner 模块,那么直接将第 3 步的参数输入到 Runner 中即可 (可选) 如果对应某些 OP 希望强制运行在 FP32 上,则可以在对应位置引入 force_fp32 装饰器 # 1 作用到 forward 函数中 ...
