在没有梯度检查点的情况下，使用PyTorch训练分类模型 我们将使用PyTorch构建一个分类模型，并在不使用梯度检查点的情况下训练它。记录模型的不同指标，如训练所用的时间、内存消耗、准确性等。由于我们主要关注GPU的内存消耗，所以在训练时需要检测每批的内存消耗。这里使用nvidia-ml-py3库，该库使用nvidia-smi命令来...
pytorch提供了两种多gpu训练的方式,方案一:利用nn.DataParallel实现,实现简单,不涉及多进程,另一种是用采用分布式并行训练torch.nn.parallel.DistributedDataParallel和torch.utils.data.distributed.DistributedSampler结合多进程实现。第二种方式效率更高,但是实现起来稍难,第二种方式同时支持多节点分布式实现。方案二的效率要...

当前安装的PyTorch支持的CUDA能力(Compute Capability)为sm_37, sm_50, sm_60, sm_70。这可以通过运行以下Python代码来确认: python import torch print(torch.cuda.get_arch_list()) 检查NVIDIA GeForce RTX 3090 GPU的CUDA能力: NVIDIA GeForce RTX 3090 GPU的CUDA能力为sm_86。这意味着其算力为8.6,超过了...
The SageMaker model parallelism (SMP) library supports PyTorch APIs for checkpoints, and provides APIs that help checkpoint properly while using the SMP library. PyTorch FSDP (Fully Sharded Data Parallelism) supports three types of checkpoints: full, sharded, and local, each serving different purpo...

Remove all aspects of CUDA and GPU driver from your machine, and do a complete reload. If the machine is a horrible mess, option 2 might really only be achievable by doing a disk wipe and OS reload, first. If option 1 doesn’t seem to work for some reason, then...
For that reason, sys is a good module to turn to when you want more verbose version information. Using platform The platform module includes a function that fetches the current version of Python. The example code below uses this function to print the current Python version number. It first ...
