ezpz
πLaunch, train and communicate across all your accelerators,
ezpz
.Full support for your favorite framework backend combo β€οΈ.
ezpz
simplifies the process of:
Setting up launching distributed training:
import ezpz as ez
RANK =
ez.setup_torch(backend=backend)
forbackend
$\in$ {DDP
,deepspeed
,horovod
}
RANK =
ez.get_rank()
LOCAL_RANK =
ez.get_local_rank()
WORLD_SIZE =
ez.get_world_size()
(see
ezpz/dist.py
for more details).
Using your favorite framework:
framework=pytorch
backend={DDP, deepspeed, horovod}
framework=tensorflow
backend=horovod
ez.get_torch_device()
: {cuda
,xpu
,mps
,cpu
}
ez.get_torch_backend()
: {nccl
,ccl
,gloo
}2ez π. (see frameworks for additional details)
Writing device agnostic code:
ezpz.get_torch_device()
>>> import ezpz as ez >>> DEVICE = ez.get_torch_device() >>> model = torch.nn.Linear(10, 10) >>> model.to(DEVICE) >>> x = torch.randn((10, 10), device=DEVICE) >>> y = model(x) >>> y.device device(type='mps', index=0)
Using
wandb
:
- Full support for any {
device
framework
backend
}:
- device: {
GPU
,XPU
,MPS
,CPU
}- framework: {
torch
,deepspeed
,horovod
,tensorflow
}- backend: {
DDP
,deepspeed
,horovod
}
