以下是我在训练的时候出现的报错 之前大概跑了几十个iteration后就出现了这个问题 现在一个都跑不了了,有没有大神可以帮我解决一下的 谢谢发布于 2019-03-21 20:21赞同13 条评论 分享喜欢收藏申请转载 写下你的评论... 3 条评论 默认 最新 璨鹿的森林 我的解决了,如果...

Please note that PyTorch uses shared memory to share data between processes, so if torch multiprocessing is used (e.g. for multithreaded data loaders) the default shared memory segment size that container runs with is not enough, and you should increase shared memory size either with --ipc=hos...

While PyTorch aggressively frees up memory, a pytorch process may not give back the memory back to the OS even after youdelyour tensors. This memory is cached so that it can be quickly allocated to new tensors being allocated without requesting the OS new extra memory. ...

通过将pin_memory=True传递给其构造函数,可以使DataLoader将batch返回到固定内存中。 使用nn.DataParallel 替代 multiprocessing 大多数涉及批量输入和多个GPU的情况应默认使用DataParallel来使用多个GPU。尽管有GIL的存在,单个python进程也可能使多个GPU饱和。 从0.1.9版本开始,大量的GPU(8+)可能未被充分利用。然而,这是一...
