pytorch将GPU上训练的model load到CPU/GPU上 假设我们只保存了模型的参数(model.state_dict())到文件名为modelparameters.pth, model = Net() 1. cpu -> cpu或者gpu -> gpu: checkpoint = torch.load('modelparameters.pth') model.load_state_dict(checkpoint) 2. cpu -> gpu 1 checkpoint =torch.load(...
如题,pytorch cpu训练很慢,使用的是开源的wenet语音识别框架,搭了一个nvidia/cuda:11.6.1-cudnn8-runtime-ubuntu20.04镜像,但用的是cpu,训练可以正常运行,性能表现是模型前向计算很慢,一个小时的训练数据,batchsize 16, num_worker 4, 模型参数量80M, 需要一个小时才能跑一个batch,16小时跑一个epoch,这是因...
多卡训练启动有两种方式,其一是pytorch自带的torchrun,其二是自行设计多进程程序。 以下为torch,distributed.launch的简单demo: 运行方式为 # 直接运行torchrun --nproc_per_node=4test.py# 等价方式python -m torch.distributed.launch --nproc_per_node=4test.py ...
cuda(0)) # run output through decoder on the next GPU out = decoder_rnn(x.cuda(1)) # normally we want to bring all outputs back to GPU 0 out = out.cuda(0) 对于这种类型的训练,无需将Lightning训练器分到任何GPU上。与之相反,只要把自己的模块导入正确的GPU的Lightning模块中: 代码语言:...
使用 CPU 卸载来支持放不进 GPU 显存的大模型训练 训练 GPT-2 XL (1.5B) 模型的命令如下:export BS=#`try with different batch sizes till you don't get OOM error,#i.e., start with larger batch size and go on decreasing till it fits on GPU`time accelerate launch run_clm_no_trainer.py ...
Fig-2是PyTorch CPU上Conv2d memory format的传递方式: 一般来说,CL的性能要优于CF,因为可以省掉activation的reorder,这也是当初去优化channels last的最大动因。 另外,PyTorch上面的默认格式是CF的,对于特定OP来说,如果没有显示的CL支持,NHWC的input会被当作non-contiguous的NCHW来处理,从而output也是NCHW的,这带来...
