The optimizer uses distribution statistics for better estimates of the cost of different query access plans. Unless it has additional information about the distribution of values between the low and high values,
This is like assuming T has an unknown random value, that is uniformly distributed on the interval [200,400]. In the case where you have better information about the distribution of T than uniform, then you should use it, computing instead the integral of f(T)^2*P(T), where P(T) is...
Distributed Training: Supports distributed data parallel (DDP), device_map simple model parallelism, DeepSpeed ZeRO2/ZeRO3, FSDP, and other distributed training techniques. Quantization Training: Supports training quantized models like BNB, AWQ, GPTQ, AQLM, HQQ, EETQ. RLHF Training: Supports huma...
TypeBoolean Default value0 Value range 0: The optimizer generates and executes a new plan without considering the plans in the plan baseline. 1: The optimizer uses plans in the plan baseline with priority and uses a new plan only after the plan is verified. ...
这个警告信息意味着在进行多GPU训练时,不推荐使用DataParallel(DP)方法,而是推荐使用torch.distributed.run命令结合DistributedDataParallel(DDP)来实现最佳的多GPU训练效果。torch.distributed.run是一个命令行工具,用于简化分布式训练的启动和管理,而DDP是一种更高效的分布式数据并行方式。 为什么使用torch.distributed.data.Di...
