Webb答：能否启用 GDRDMA 和 NCCL 版本有关，经测试，使用 PyTorch1.7（自带 NCCL2.7.8）时，启动 GDRDMA 失败，和 Nvidia 的人沟通后确定是 NCCL 高版本的 bug，暂时使用的运行注入的方式来修复；使用 PyTorch1.6（自带 NCCL2.4.8）时，能够启用 GDRDMA。 WebbYou can disable distributed mode and switch to threading based data parallel as follows: % python -m espnet2.bin.asr_train --ngpu 4 --multiprocessing_distributed false. If you meet some errors with distributed mode, please try single gpu mode or multi-GPUs with --multiprocessing_distributed false before reporting the issue.
