ResNet50混合精度训练test阶段出现core dump问题

Created by: wzzju

1、环境配置

  • PaddlePaddle版本：Paddle develop分支代码。

  • CPU/GPU（GPU驱动、CUDA、cuDNN版本）：Intel(R) Xeon(R) Gold 6148 CPU @ 2.40GHz; Tesla V100; CUDA 10; CUDNN 7.6.4

  • 操作系统版本：Ubuntu 14.04

  • Python版本：Python 3.7

  • 显存信息：16 GB

2、BUG复现步骤（必要时给出截图）：

CUDA_VISIBLE_DEVICES=0 python -m paddle.distributed.launch \
	--selected_gpus=0 \
	--use_paddlecloud \
	--log_dir mylog \
	./train_with_fleet.py \
	--model=ResNet50 \
	--total_images=1281167 \
	--data_dir=./ImageNet \
	--class_dim=1000 \
	--image_shape=3,224,224 \
	--model_save_dir=output/ \
	--with_mem_opt=False \
	--lr_strategy=piecewise_decay \
	--l2_decay=1e-4 \
	--num_threads=3 \
	--do_test=True \
	--use_hierarchical_allreduce=0 \
	--fuse=True \
	--batch_size=256 \
	--fp16=True \
	--num_epochs=2 \
	--scale_loss=128.0 \
	--lr=0.1 \
	--use_dali=True \
	--data_format=NHWC

3、期望结果：

  • ResNet50混合精度训练可正常进行train和test过程。

4、实际结果（必要时给出截图，报错信息、日志/代码关键片段）：

  • 运行到test阶段的最后一两个batch时会出现core dumped错误。

  • log如下：
