ZeroRedundancyOptimizer 可以与 torch.nn.parallel.DistributedDataParallel 结合使用,以减少 per-rank 峰值内存消耗。 ZeroRedundancyOptimizer 使用sorted-greedy 算法在每个等级打包多个参数。每个参数都属于一个等级,并且不分等级。分区是任意的,可能与参数注册或使用顺序不匹配。 例子: >>> import torch.nn as nn >...

官网:Celery - Distributed Task Queue Celery python生态圈无可替代的异步任务队列,用户请求时如果触发一个慢速的任务,但是用户当前并不关心结果,就可以放在celery里面满满执行 4· PyToolz 官网:PyToolz API Documentation PyToolz toolz库是几乎每个程序设计语言都有的函数式编程库。函数式编程范式的流行是有一定道理...
torch.nonzero(..., as_tuple=False)(默认)返回一个二维张量,其中每行都是非零值的索引。 torch.nonzero(..., as_tuple=True) 返回一维索引张量的元组,允许高级索引,因此 x[x.nonzero(as_tuple=True)] 给出张量 x 的所有非零值。在返回的元组中,每个索引张量都包含特定维度的非零索引。 有关这两种行...
With PyTorch, we use a technique called reverse-mode auto-differentiation, which allows you to change the way your network behaves arbitrarily with zero lag or overhead. Our inspiration comes from several research papers on this topic, as well as current and past work such astorch-autograd,auto...
我们希望能从患者住院期间的临床记录来预测该患者未来30天内是否会再次入院,该预测可以辅助医生更好的选择治疗方案并对手术风险进行评估。在临床中治疗手段...
DASK is an integrated component of RAPIDS for distributed computation on GPUs. You can take advantage of it to distribute the Monte Carlo simulation computation to multiple GPUs across multiple nodes. First, wrap all the computation inside a function to allow the allocated GPU memory to be ...
Distiller 是 Intel 开源的一个用于神经网络压缩的 Python 包,可减少深度神经网络的内存占用、提高推断速度并节省能耗
