在CentOS上进行PyTorch性能测试,可以通过以下步骤进行:
sudo yum update -y
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh
conda create -n pytorch python=3.8
conda activate pytorch
pip install torch torchvision torchaudio
pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu117
import torch
print(torch.__version__)
print(torch.cuda.is_available())
import torch
import torchvision.models as models
from torch.profiler import profile, record_function, ProfilerActivity
model = models.resnet18()
inputs = torch.randn(5, 3, 224, 224)
with profile(activities=[ProfilerActivity.CPU], record_shapes=True) as prof:
with record_function("model_inference"):
model(inputs)
print(prof.key_averages().table(sort_by="cpu_time_total", row_limit=10))
from torch.utils.tensorboard import SummaryWriter
writer = SummaryWriter('runs/experiment-1')
writer.add_graph(model, inputs)
writer.close()
使用DistributedDataParallel
进行多GPU训练,比较其与DataParallel
的性能差异。
num_workers
。pin_memory
。torch.backends.cudnn.benchmark = true
。通过这些步骤和策略,可以在CentOS上对PyTorch进行性能测试和优化,以确保深度学习模型的高效运行。
