pycharm ValueError: source code string cannot contain null bytes在GitHub下载的代码在win10上调试遇到错误首先检测python代码中的from，调整目录。如下：用lib.xvision等依次导入需要的函数。from lib.datasets import GeneralDataset as Datasetfrom lib.xvision import transformsfrom lib.xvision.visualizati

pytorch 单gpu改为多gpu训练和测试训练中在plfd_backbone = plfd_backbone.to(device)之前加import torch.nn as nnplfd_backbone = nn.DataParallel(plfd_backbone, device_ids = [0, 1, 2, 3])device_ids:设置gpu个数。测试时，同样要修改在to(device)后加入pfld_backbone = nn.DataParallel(pfld_ba
