# Launching Multi-GPU Training from a Jupyter Environment
This tutorial teaches you how to fine tune a computer vision model with 🤗 Accelerate from a Jupyter Notebook on a distributed system.
You will also learn how to setup a few requirements needed for ensuring your environment is configured properly, your data has been prepared properly, and finally how to launch training.
<Tip>
This tutorial is also available as a Jupyter Notebook [here](https://github.com/huggingface/notebooks/blob/main/examples/accelerate_examples/simple_cv_example.ipynb)
</Tip>
## Configuring the Environment
Before any training can be performed, a 🤗 Accelerate config file must exist in the system. Usually this can be done by running the following in a terminal and answering the prompts:
```bash
accelerate config
```
However, if general defaults are fine and you are *not* running on a TPU, 🤗Accelerate has a utility to quickly write your GPU configuration into a config file via [`utils.write_basic_config`].
The following code will restart Jupyter after writing the configuration, as CUDA code was called to perform this.
<Tip warning={true}>
CUDA can't be initialized more than once on a multi-GPU system. It's fine to debug in the notebook and have calls to CUDA, but in order to finally train a full cleanup and restart will need to be performed.
</Tip>
```python
import os
from accelerate.utils import write_basic_config
write_basic_config() # Write a config file
os._exit(00) # Restart the notebook
```
## Preparing the Dataset and Model
Next you should prepare your dataset. As mentioned at earlier, great care should be taken when preparing the `DataLoaders` and model to make sure that **nothing** is put on *any* GPU.
If you do, it is recommended to put that specific code into a function and call that from within the notebook launcher interface, which will be shown later.
Make sure the dataset is downloaded based on the directions [here](https://github.com/huggingface/accelerate/tree/main/examples#simple-vision-example)
```python
import os, re, torch, PIL
import numpy as np
from torch.optim.lr_scheduler import OneCycleLR
from torch.utils.data import DataLoader, Dataset
from torchvision.transforms import Compose, RandomResizedCrop, Resize, ToTensor
from accelerate import Accelerator
from accelerate.utils import set_seed
from timm import create_model
```
First you need to create a function to extract the class name based on a filename:
```python
import os
data_dir = "../../images"
fnames = os.listdir(data_dir)
fname = fnames[0]
print(fname)
```
```python out
beagle_32.jpg
```
In the case here, the label is `beagle`. Using regex you can extract the label from the filename:
```python
import re
def extract_label(fname):
stem = fname.split(os.path.sep)[-1]
return re.search(r"^(.*)_\d+\.jpg$", stem).groups()[0]
```
```python
extract_label(fname)
```
And you can see it properly returned the right name for our file:
```python out
"beagle"
```
Next a `Dataset` class should be made to handle grabbing the image and the label:
```python
class PetsDataset(Dataset):
def __init__(self, file_names, image_transform=None, label_to_id=None):
self.file_names = file_names
self.image_transform = image_transform
self.label_to_id = label_to_id
def __len__(self):
return len(self.file_names)
def __getitem__(self, idx):
fname = self.file_names[idx]
raw_image = PIL.Image.open(fname)
image = raw_image.convert("RGB")
if self.image_transform is not None:
image = self.image_transform(image)
label = extract_label(fname)
if self.label_to_id is not None:
label = self.label_to_id[label]
return {"image": image, "label": label}
```
Now to build the dataset. Outside the training function you can find and declare all the filenames and labels and use them as references inside the
launched function:
```python
fnames = [os.path.join("../../images", fname) for fname in fnames if fname.endswith(".jpg")]
```
Next gather all the labels:
```python
all_labels = [extract_label(fname) for fname in fnames]
id_to_label = list(set(all_labels))
id_to_label.sort()
label_to_id = {lbl: i for i, lbl in enumerate(id_to_label)}
```
Next, you should make a `get_dataloaders` function that will return your built dataloaders for you. As mentioned earlier, if data is automatically
sent to the GPU or a TPU device when building your `DataLoaders`, they must be built using this method.
```python
def get_dataloaders(batch_size: int = 64):
"Builds a set of dataloaders with a batch_size"
random_perm = np.random.permutation(len(fnames))
cut = int(0.8 * len(fnames))
train_split = random_perm[:cut]
eval_split = random_perm[cut:]
# For training a simple RandomResizedCrop will be used
train_tfm = Compose([RandomResizedCrop((224, 224), scale=(0.5, 1.0)), ToTensor()])
train_dataset = PetsDataset([fnames[i] for i in train_split], image_transform=train_tfm, label_to_id=label_to_id)
# For evaluation a deterministic Resize will be used
eval_tfm = Compose([Resize((224, 224)), ToTensor()])
eval_dataset = PetsDataset([fnames[i] for i in eval_split], image_transform=eval_tfm, label_to_id=label_to_id)
# Instantiate dataloaders
train_dataloader = DataLoader(train_dataset, shuffle=True, batch_size=batch_size, num_workers=4)
eval_dataloader = DataLoader(eval_dataset, shuffle=False, batch_size=batch_size * 2, num_workers=4)
return train_dataloader, eval_dataloader
```
Finally, you should import the scheduler to be used later:
```python
from torch.optim.lr_scheduler import CosineAnnealingLR
```
## Writing the Training Function
Now you can build the training loop. [`notebook_launcher`] works by passing in a function to call that will be ran across the distributed system.
Here is a basic training loop for the animal classification problem:
<Tip>
The code has been split up to allow for explanations on each section. A full version that can be copy and pasted will be available at the end
</Tip>
```python
def training_loop(mixed_precision="fp16", seed: int = 42, batch_size: int = 64):
set_seed(seed)
accelerator = Accelerator(mixed_precision=mixed_precision)
```
First you should set the seed and create an [`Accelerator`] object as early in the training loop as possible.
<Tip warning={true}>
If training on the TPU, your training loop should take in the model as a parameter and it should be instantiated
outside of the training loop function. See the [TPU best practices](../concept_guides/training_tpu)
to learn why
</Tip>
Next you should build your dataloaders and create your model:
```python
train_dataloader, eval_dataloader = get_dataloaders(batch_size)
model = create_model("resnet50d", pretrained=True, num_classes=len(label_to_id))
```
<Tip>
You build the model here so that the seed also controls the new weight initialization
</Tip>
As you are performing transfer learning in this example, the encoder of the model starts out frozen so the head of the model can be
trained only initially:
```python
for param in model.parameters():
param.requires_grad = False
for param in model.get_classifier().parameters():
param.requires_grad = True
```
Normalizing the batches of images will make training a little faster:
```python
mean = torch.tensor(model.default_cfg["mean"])[None, :, None, None]
std = torch.tensor(model.default_cfg["std"])[None, :, None, None]
```
To make these constants available on the active device, you should set it to the Accelerator's device:
```python
mean = mean.to(accelerator.device)
std = std.to(accelerator.device)
```
Next instantiate the rest of the PyTorch classes used for training:
```python
optimizer = torch.optim.Adam(params=model.parameters(), lr=3e-2 / 25)
lr_scheduler = OneCycleLR(optimizer=optimizer, max_lr=3e-2, epochs=5, steps_per_epoch=len(train_dataloader))
```
Before passing everything to [`~Accelerator.prepare`].
<Tip>
There is no specific order to remember, you just need to unpack the objects in the same order you gave them to the prepare method.
</Tip>
```python
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler = accelerator.prepare(
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler
)
```
Now train the model:
```python
for epoch in range(5):
model.train()
for batch in train_dataloader:
inputs = (batch["image"] - mean) / std
outputs = model(inputs)
loss = torch.nn.functional.cross_entropy(outputs, batch["label"])
accelerator.backward(loss)
optimizer.step()
lr_scheduler.step()
optimizer.zero_grad()
```
The evaluation loop will look slightly different compared to the training loop. The number of elements passed as well as the overall
total accuracy of each batch will be added to two constants:
```python
model.eval()
accurate = 0
num_elems = 0
```
Next you have the rest of your standard PyTorch loop:
```python
for batch in eval_dataloader:
inputs = (batch["image"] - mean) / std
with torch.no_grad():
outputs = model(inputs)
predictions = outputs.argmax(dim=-1)
```
Before finally the last major difference.
When performing distributed evaluation, the predictions and labels need to be passed through
[`~Accelerator.gather`] so that all of the data is available on the current device and a properly calculated metric can be achieved:
```python
accurate_preds = accelerator.gather(predictions) == accelerator.gather(batch["label"])
num_elems += accurate_preds.shape[0]
accurate += accurate_preds.long().sum()
```
Now you just need to calculate the actual metric for this problem, and you can print it on the main process using [`~Accelerator.print`]:
```python
eval_metric = accurate.item() / num_elems
accelerator.print(f"epoch {epoch}: {100 * eval_metric:.2f}")
```
A full version of this training loop is available below:
```python
def training_loop(mixed_precision="fp16", seed: int = 42, batch_size: int = 64):
set_seed(seed)
# Initialize accelerator
accelerator = Accelerator(mixed_precision=mixed_precision)
# Build dataloaders
train_dataloader, eval_dataloader = get_dataloaders(batch_size)
# Instantiate the model (you build the model here so that the seed also controls new weight initaliziations)
model = create_model("resnet50d", pretrained=True, num_classes=len(label_to_id))
# Freeze the base model
for param in model.parameters():
param.requires_grad = False
for param in model.get_classifier().parameters():
param.requires_grad = True
# You can normalize the batches of images to be a bit faster
mean = torch.tensor(model.default_cfg["mean"])[None, :, None, None]
std = torch.tensor(model.default_cfg["std"])[None, :, None, None]
# To make these constants available on the active device, set it to the accelerator device
mean = mean.to(accelerator.device)
std = std.to(accelerator.device)
# Instantiate the optimizer
optimizer = torch.optim.Adam(params=model.parameters(), lr=3e-2 / 25)
# Instantiate the learning rate scheduler
lr_scheduler = OneCycleLR(optimizer=optimizer, max_lr=3e-2, epochs=5, steps_per_epoch=len(train_dataloader))
# Prepare everything
# There is no specific order to remember, you just need to unpack the objects in the same order you gave them to the
# prepare method.
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler = accelerator.prepare(
model, optimizer, train_dataloader, eval_dataloader, lr_scheduler
)
# Now you train the model
for epoch in range(5):
model.train()
for batch in train_dataloader:
inputs = (batch["image"] - mean) / std
outputs = model(inputs)
loss = torch.nn.functional.cross_entropy(outputs, batch["label"])
accelerator.backward(loss)
optimizer.step()
lr_scheduler.step()
optimizer.zero_grad()
model.eval()
accurate = 0
num_elems = 0
for batch in eval_dataloader:
inputs = (batch["image"] - mean) / std
with torch.no_grad():
outputs = model(inputs)
predictions = outputs.argmax(dim=-1)
accurate_preds = accelerator.gather(predictions) == accelerator.gather(batch["label"])
num_elems += accurate_preds.shape[0]
accurate += accurate_preds.long().sum()
eval_metric = accurate.item() / num_elems
# Use accelerator.print to print only on the main process.
accelerator.print(f"epoch {epoch}: {100 * eval_metric:.2f}")
```
## Using the notebook_launcher
All that's left is to use the [`notebook_launcher`].
You pass in the function, the arguments (as a tuple), and the number of processes to train on. (See the [documentation](../package_reference/launchers) for more information)
```python
from accelerate import notebook_launcher
```
```python
args = ("fp16", 42, 64)
notebook_launcher(training_loop, args, num_processes=2)
```
In the case of running on multiple nodes, you need to set up a Jupyter session at each node and run the launching cell at the same time.
For an environment containing 2 nodes (computers) with 8 GPUs each and the main computer with an IP address of "172.31.43.8", it would look like so:
```python
notebook_launcher(training_loop, args, master_addr="172.31.43.8", node_rank=0, num_nodes=2, num_processes=8)
```
And in the second Jupyter session on the other machine:
<Tip>
Notice how the `node_rank` has changed
</Tip>
```python
notebook_launcher(training_loop, args, master_addr="172.31.43.8", node_rank=1, num_nodes=2, num_processes=8)
```
In the case of running on the TPU, it would look like so:
```python
model = create_model("resnet50d", pretrained=True, num_classes=len(label_to_id))
args = (model, "fp16", 42, 64)
notebook_launcher(training_loop, args, num_processes=8)
```
As it's running it will print the progress as well as state how many devices you ran on. This tutorial was ran with two GPUs:
```python out
Launching training on 2 GPUs.
epoch 0: 88.12
epoch 1: 91.73
epoch 2: 92.58
epoch 3: 93.90
epoch 4: 94.71
```
And that's it!
Please note that [`notebook_launcher`] ignores the 🤗 Accelerate config file, to launch based on the config use:
```bash
accelerate launch
```
## Debugging
A common issue when running the `notebook_launcher` is receiving a CUDA has already been initialized issue. This usually stems
from an import or prior code in the notebook that makes a call to the PyTorch `torch.cuda` sublibrary. To help narrow down what went wrong,
you can launch the `notebook_launcher` with `ACCELERATE_DEBUG_MODE=yes` in your environment and an additional check
will be made when spawning that a regular process can be created and utilize CUDA without issue. (Your CUDA code can still be ran afterwards).
## Conclusion
This notebook showed how to perform distributed training from inside of a Jupyter Notebook. Some key notes to remember:
- Make sure to save any code that use CUDA (or CUDA imports) for the function passed to [`notebook_launcher`]
- Set the `num_processes` to be the number of devices used for training (such as number of GPUs, CPUs, TPUs, etc)
- If using the TPU, declare your model outside the training loop function

# DeepSpeed
[DeepSpeed](https://github.com/microsoft/DeepSpeed) implements everything described in the [ZeRO paper](https://arxiv.org/abs/1910.02054). Some of the salient optimizations are:
1. Optimizer state partitioning (ZeRO stage 1)
2. Gradient partitioning (ZeRO stage 2)
3. Parameter partitioning (ZeRO stage 3)
4. Custom mixed precision training handling
5. A range of fast CUDA-extension-based optimizers
6. ZeRO-Offload to CPU and Disk/NVMe
7. Hierarchical partitioning of model parameters (ZeRO++)
ZeRO-Offload has its own dedicated paper: [ZeRO-Offload: Democratizing Billion-Scale Model Training](https://arxiv.org/abs/2101.06840). And NVMe-support is described in the paper [ZeRO-Infinity: Breaking the GPU
Memory Wall for Extreme Scale Deep Learning](https://arxiv.org/abs/2104.07857).
DeepSpeed ZeRO-2 is primarily used only for training, as its features are of no use to inference.
DeepSpeed ZeRO-3 can be used for inference as well since it allows huge models to be loaded on multiple GPUs, which
won't be possible on a single GPU.
🤗 Accelerate integrates [DeepSpeed](https://github.com/microsoft/DeepSpeed) via 2 options:
1. Integration of the DeepSpeed features via `deepspeed config file` specification in `accelerate config` . You just supply your custom config file or use our template. Most of
this document is focused on this feature. This supports all the core features of DeepSpeed and gives user a lot of flexibility.
User may have to change a few lines of code depending on the config.
2. Integration via `deepspeed_plugin`.This supports subset of the DeepSpeed features and uses default options for the rest of the configurations.
User need not change any code and is good for those who are fine with most of the default settings of DeepSpeed.
## What is integrated?
Training:
1. 🤗 Accelerate integrates all features of DeepSpeed ZeRO. This includes all the ZeRO stages 1, 2 and 3 as well as ZeRO-Offload, ZeRO-Infinity (which can offload to disk/NVMe) and ZeRO++.
Below is a short description of Data Parallelism using ZeRO - Zero Redundancy Optimizer along with diagram from this [blog post](https://www.microsoft.com/en-us/research/blog/zero-deepspeed-new-system-optimizations-enable-training-models-with-over-100-billion-parameters/)
(Source: [link](https://www.microsoft.com/en-us/research/blog/zero-deepspeed-new-system-optimizations-enable-training-models-with-over-100-billion-parameters/))
a. **Stage 1** : Shards optimizer states across data parallel workers/GPUs
b. **Stage 2** : Shards optimizer states + gradients across data parallel workers/GPUs
c. **Stage 3**: Shards optimizer states + gradients + model parameters across data parallel workers/GPUs
d. **Optimizer Offload**: Offloads the gradients + optimizer states to CPU/Disk building on top of ZERO Stage 2
e. **Param Offload**: Offloads the model parameters to CPU/Disk building on top of ZERO Stage 3
f. **Hierarchical Partitioning**: Enables efficient multi-node training with data-parallel training across nodes and ZeRO-3 sharding within a node, built on top of ZeRO Stage 3.
<u>Note</u>: With respect to Disk Offload, the disk should be an NVME for decent speed but it technically works on any Disk
Inference:
1. DeepSpeed ZeRO Inference supports ZeRO stage 3 with ZeRO-Infinity. It uses the same ZeRO protocol as training, but
it doesn't use an optimizer and a lr scheduler and only stage 3 is relevant. For more details see:
[deepspeed-zero-inference](#deepspeed-zero-inference).
## How it works?
**Pre-Requisites**: Install DeepSpeed version >=0.6.5. Please refer to the [DeepSpeed Installation details](https://github.com/microsoft/DeepSpeed#installation)
for more information.
We will first look at easy to use integration via `accelerate config`.
Followed by more flexible and feature rich `deepspeed config file` integration.
### Accelerate DeepSpeed Plugin
On your machine(s) just run:
```bash
accelerate config
```
and answer the questions asked. It will ask whether you want to use a config file for DeepSpeed to which you should answer no. Then answer the following questions to generate a basic DeepSpeed config.
This will generate a config file that will be used automatically to properly set the
default options when doing
```bash
accelerate launch my_script.py --args_to_my_script
```
For instance, here is how you would run the NLP example `examples/nlp_example.py` (from the root of the repo) with DeepSpeed Plugin:
**ZeRO Stage-2 DeepSpeed Plugin Example**
```bash
compute_environment: LOCAL_MACHINE
deepspeed_config:
gradient_accumulation_steps: 1
gradient_clipping: 1.0
offload_optimizer_device: none
offload_param_device: none
zero3_init_flag: true
zero_stage: 2
distributed_type: DEEPSPEED
fsdp_config: {}
machine_rank: 0
main_process_ip: null
main_process_port: null
main_training_function: main
mixed_precision: fp16
num_machines: 1
num_processes: 2
use_cpu: false
```
```bash
accelerate launch examples/nlp_example.py --mixed_precision fp16
```
**ZeRO Stage-3 with CPU Offload DeepSpeed Plugin Example**
```bash
compute_environment: LOCAL_MACHINE
deepspeed_config:
gradient_accumulation_steps: 1
gradient_clipping: 1.0
offload_optimizer_device: cpu
offload_param_device: cpu
zero3_init_flag: true
zero3_save_16bit_model: true
zero_stage: 3
distributed_type: DEEPSPEED
fsdp_config: {}
machine_rank: 0
main_process_ip: null
main_process_port: null
main_training_function: main
mixed_precision: fp16
num_machines: 1
num_processes: 2
use_cpu: false
```
```bash
accelerate launch examples/nlp_example.py --mixed_precision fp16
```
Currently, `Accelerate` supports following config through the CLI:
```bash
`zero_stage`: [0] Disabled, [1] optimizer state partitioning, [2] optimizer+gradient state partitioning and [3] optimizer+gradient+parameter partitioning
`gradient_accumulation_steps`: Number of training steps to accumulate gradients before averaging and applying them.

`offload_param_device`: [none] Disable parameter offloading, [cpu] offload parameters to CPU, [nvme] offload parameters to NVMe SSD. Only applicable with ZeRO Stage-3.
`offload_param_nvme_path`: Decides Nvme Path to offload parameters. If unspecified, will default to 'none'.
`zero3_init_flag`: Decides whether to enable `deepspeed.zero.Init` for constructing massive models. Only applicable with ZeRO Stage-3.
`zero3_save_16bit_model`: Decides whether to save 16-bit model weights when using ZeRO Stage-3.
`mixed_precision`: `no` for FP32 training, `fp16` for FP16 mixed-precision training and `bf16` for BF16 mixed-precision training.
`deepspeed_moe_layer_cls_names`: Comma-separated list of transformer Mixture-of-Experts (MoE) layer class names (case-sensitive) to wrap ,e.g, `MixtralSparseMoeBlock`, `Qwen2MoeSparseMoeBlock`, `JetMoEAttention,JetMoEBlock` ...
`deepspeed_hostfile`: DeepSpeed hostfile for configuring multi-node compute resources.
`deepspeed_exclusion_filter`: DeepSpeed exclusion filter string when using mutli-node setup.
`deepspeed_inclusion_filter`: DeepSpeed inclusion filter string when using mutli-node setup.
`deepspeed_multinode_launcher`: DeepSpeed multi-node launcher to use. If unspecified, will default to `pdsh`.
`deepspeed_config_file`: path to the DeepSpeed config file in `json` format. See the next section for more details on this.
```
To be able to tweak more options, you will need to use a DeepSpeed config file.
### DeepSpeed Config File
On your machine(s) just run:
```bash
accelerate config
```
and answer the questions asked. It will ask whether you want to use a config file for deepspeed to which you answer yes
and provide the path to the deepspeed config file.
This will generate a config file that will be used automatically to properly set the
default options when doing
```bash
accelerate launch my_script.py --args_to_my_script
```
For instance, here is how you would run the NLP example `examples/by_feature/deepspeed_with_config_support.py` (from the root of the repo) with DeepSpeed Config File:

**ZeRO++ Config Example**
You can use the features of ZeRO++ by using the appropriate config parameters. Note that ZeRO++ is an extension for ZeRO Stage 3. Here is how the config file can be modified, from [DeepSpeed's ZeRO++ tutorial](https://www.deepspeed.ai/tutorials/zeropp/):
```json
{
"zero_optimization": {
"stage": 3,
"reduce_bucket_size": "auto",
"zero_quantized_weights": true,
"zero_hpz_partition_size": 8,
"zero_quantized_gradients": true,
"contiguous_gradients": true,
"overlap_comm": true
}
}
```
For hierarchical partitioning, the partition size `zero_hpz_partition_size` should ideally be set to the number of GPUs per node. (For example, the above config file assumes 8 GPUs per node)
**Important code changes when using DeepSpeed Config File**
1. DeepSpeed Optimizers and Schedulers. For more information on these,
see the [DeepSpeed Optimizers](https://deepspeed.readthedocs.io/en/latest/optimizers.html) and [DeepSpeed Schedulers](https://deepspeed.readthedocs.io/en/latest/schedulers.html) documentation.
We will look at the changes needed in the code when using these.
a. DS Optim + DS Scheduler: The case when both `optimizer` and `scheduler` keys are present in the DeepSpeed config file.
In this situation, those will be used and the user has to use `accelerate.utils.DummyOptim` and `accelerate.utils.DummyScheduler` to replace the PyTorch/Custom optimizers and schedulers in their code.
Below is the snippet from `examples/by_feature/deepspeed_with_config_support.py` showing this:
```python
# Creates Dummy Optimizer if `optimizer` was specified in the config file else creates Adam Optimizer
optimizer_cls = (
torch.optim.AdamW
if accelerator.state.deepspeed_plugin is None
or "optimizer" not in accelerator.state.deepspeed_plugin.deepspeed_config
else DummyOptim
)
optimizer = optimizer_cls(optimizer_grouped_parameters, lr=args.learning_rate)
# Creates Dummy Scheduler if `scheduler` was specified in the config file else creates `args.lr_scheduler_type` Scheduler
if (
accelerator.state.deepspeed_plugin is None
or "scheduler" not in accelerator.state.deepspeed_plugin.deepspeed_config
):
lr_scheduler = get_scheduler(
name=args.lr_scheduler_type,
optimizer=optimizer,
num_warmup_steps=args.num_warmup_steps,
num_training_steps=args.max_train_steps,
)
else:
lr_scheduler = DummyScheduler(
optimizer, total_num_steps=args.max_train_steps, warmup_num_steps=args.num_warmup_steps
)
```
b. Custom Optim + Custom Scheduler: The case when both `optimizer` and `scheduler` keys are absent in the DeepSpeed config file.
In this situation, no code changes are needed from the user and this is the case when using integration via DeepSpeed Plugin.
In the above example we can see that the code remains unchanged if the `optimizer` and `scheduler` keys are absent in the DeepSpeed config file.
c. Custom Optim + DS Scheduler: The case when only `scheduler` key is present in the DeepSpeed config file.
In this situation, the user has to use `accelerate.utils.DummyScheduler` to replace the PyTorch/Custom scheduler in their code.
d. DS Optim + Custom Scheduler: The case when only `optimizer` key is present in the DeepSpeed config file.
This will result in an error because you can only use DS Scheduler when using DS Optim.
2. Notice the `auto` values in the above example DeepSpeed config files. These are automatically handled by `prepare` method
based on model, dataloaders, dummy optimizer and dummy schedulers provided to `prepare` method.
Only the `auto` fields specified in above examples are handled by `prepare` method and the rest have to be explicitly specified by the user.
The `auto` values are calculated as:
- `reduce_bucket_size`: `hidden_size * hidden_size`
- `stage3_prefetch_bucket_size`: `0.9 * hidden_size * hidden_size`
- `stage3_param_persistence_threshold`: `10 * hidden_size`
For the `auto` feature to work for these 3 config entries - Accelerate will use `model.config.hidden_size` or `max(model.config.hidden_sizes)` as `hidden_size`. If neither of these is available, the launching will fail and you will have to set these 3 config entries manually. Remember the first 2 config entries are the communication buffers - the larger they are the more efficient the comms will be, and the larger they are the more GPU memory they will consume, so it's a tunable performance trade-off.
**Things to note when using DeepSpeed Config File**
Below is a sample script using `deepspeed_config_file` in different scenarios.
Code `test.py`:
```python
from accelerate import Accelerator
from accelerate.state import AcceleratorState
def main():
accelerator = Accelerator()
accelerator.print(f"{AcceleratorState()}")
if __name__ == "__main__":
main()
```
**Scenario 1**: Manually tampered accelerate config file having `deepspeed_config_file` along with other entries.
1. Content of the `accelerate` config:
```yaml
command_file: null
commands: null
compute_environment: LOCAL_MACHINE
deepspeed_config:
gradient_accumulation_steps: 1
gradient_clipping: 1.0
offload_optimizer_device: 'cpu'
offload_param_device: 'cpu'
zero3_init_flag: true
zero3_save_16bit_model: true
zero_stage: 3
deepspeed_config_file: 'ds_config.json'
distributed_type: DEEPSPEED
downcast_bf16: 'no'
dynamo_backend: 'NO'
fsdp_config: {}
gpu_ids: null
machine_rank: 0
main_process_ip: null

num_machines: 1
num_processes: 2
rdzv_backend: static
same_network: true
tpu_name: null
tpu_zone: null
use_cpu: false
```
2. `ds_config.json`:
```json
{
"bf16": {
"enabled": true
},
"zero_optimization": {
"stage": 3,
"stage3_gather_16bit_weights_on_model_save": false,
"offload_optimizer": {
"device": "none"
},
"offload_param": {
"device": "none"
}
},
"gradient_clipping": 1.0,
"train_batch_size": "auto",
"train_micro_batch_size_per_gpu": "auto",
"gradient_accumulation_steps": 10,
"steps_per_print": 2000000
}
```
3. Output of `accelerate launch test.py`:
```bash
ValueError: When using `deepspeed_config_file`, the following accelerate config variables will be ignored:
['gradient_accumulation_steps', 'gradient_clipping', 'zero_stage', 'offload_optimizer_device', 'offload_param_device',
'zero3_save_16bit_model', 'mixed_precision'].
Please specify them appropriately in the DeepSpeed config file.
If you are using an accelerate config file, remove other config variables mentioned in the above specified list.
The easiest method is to create a new config following the questionnaire via `accelerate config`.
It will only ask for the necessary config variables when using `deepspeed_config_file`.
```
**Scenario 2**: Use the solution of the error to create new accelerate config and check that no ambiguity error is now thrown.
1. Run `accelerate config`:
```bash
$ accelerate config
-------------------------------------------------------------------------------------------------------------------------------
In which compute environment are you running?
This machine
-------------------------------------------------------------------------------------------------------------------------------
Which type of machine are you using?
multi-GPU
How many different machines will you use (use more than 1 for multi-node training)? [1]:
Do you wish to optimize your script with torch dynamo?[yes/NO]:
Do you want to use DeepSpeed? [yes/NO]: yes
Do you want to specify a json file to a DeepSpeed config? [yes/NO]: yes
Please enter the path to the json DeepSpeed config file: ds_config.json
Do you want to enable `deepspeed.zero.Init` when using ZeRO Stage-3 for constructing massive models? [yes/NO]: yes
How many GPU(s) should be used for distributed training? [1]:4
accelerate configuration saved at ds_config_sample.yaml
```
2. Content of the `accelerate` config:
```yaml
compute_environment: LOCAL_MACHINE
deepspeed_config:
deepspeed_config_file: ds_config.json
zero3_init_flag: true
distributed_type: DEEPSPEED
downcast_bf16: 'no'
dynamo_backend: 'NO'
fsdp_config: {}
machine_rank: 0
main_training_function: main
megatron_lm_config: {}
num_machines: 1
num_processes: 4
rdzv_backend: static
same_network: true
use_cpu: false
```
3. Output of `accelerate launch test.py`:
```bash
Distributed environment: DEEPSPEED Backend: nccl
Num processes: 4
Process index: 0
Local process index: 0
Device: cuda:0
Mixed precision type: bf16
ds_config: {'bf16': {'enabled': True}, 'zero_optimization': {'stage': 3, 'stage3_gather_16bit_weights_on_model_save': False, 'offload_optimizer': {'device': 'none'}, 'offload_param': {'device': 'none'}}, 'gradient_clipping': 1.0, 'train_batch_size': 'auto', 'train_micro_batch_size_per_gpu': 'auto', 'gradient_accumulation_steps': 10, 'steps_per_print': inf, 'fp16': {'enabled': False}}
```
**Scenario 3**: Setting the `accelerate launch` command arguments related to DeepSpeed as `"auto"` in the DeepSpeed` configuration file and check that things work as expected.
1. New `ds_config.json` with `"auto"` for the `accelerate launch` DeepSpeed command arguments:
```json
{
"bf16": {
"enabled": "auto"
},
"zero_optimization": {
"stage": "auto",
"stage3_gather_16bit_weights_on_model_save": "auto",
"offload_optimizer": {
"device": "auto"
},
"offload_param": {
"device": "auto"
}
},
"gradient_clipping": "auto",
"train_batch_size": "auto",
"train_micro_batch_size_per_gpu": "auto",
"gradient_accumulation_steps": "auto",
"steps_per_print": 2000000
}
```
2. Output of `accelerate launch --mixed_precision="fp16" --zero_stage=3 --gradient_accumulation_steps=5 --gradient_clipping=1.0 --offload_param_device="cpu" --offload_optimizer_device="nvme" --zero3_save_16bit_model="true" test.py`:
```bash
Distributed environment: DEEPSPEED Backend: nccl
Num processes: 4
Process index: 0
Local process index: 0
Device: cuda:0
Mixed precision type: fp16
ds_config: {'bf16': {'enabled': False}, 'zero_optimization': {'stage': 3, 'stage3_gather_16bit_weights_on_model_save': True, 'offload_optimizer': {'device': 'nvme'}, 'offload_param': {'device': 'cpu'}}, 'gradient_clipping': 1.0, 'train_batch_size': 'auto', 'train_micro_batch_size_per_gpu': 'auto', 'gradient_accumulation_steps': 5, 'steps_per_print': inf, 'fp16': {'enabled': True, 'auto_cast': True}}
```
**Note**:
1. Remaining `"auto"` values are handled in `accelerator.prepare()` call as explained in point 2 of
`Important code changes when using DeepSpeed Config File`.
2. Only when `gradient_accumulation_steps` is `auto`, the value passed while creating `Accelerator` object via `Accelerator(gradient_accumulation_steps=k)` will be used. When using DeepSpeed Plugin, the value from it will be used and it will overwrite the value passed while creating Accelerator object.
## Saving and loading
1. Saving and loading of models is unchanged for ZeRO Stage-1 and Stage-2.
2. under ZeRO Stage-3, `state_dict` contains just the placeholders since the model weights are partitioned across multiple GPUs.
ZeRO Stage-3 has 2 options:
a. Saving the entire 16bit model weights to directly load later on using `model.load_state_dict(torch.load(pytorch_model.bin))`.
For this, either set `zero_optimization.stage3_gather_16bit_weights_on_model_save` to True in DeepSpeed Config file or set
`zero3_save_16bit_model` to True in DeepSpeed Plugin.
**Note that this option requires consolidation of the weights on one GPU it can be slow and memory demanding, so only use this feature when needed.**
Below is the snippet from `examples/by_feature/deepspeed_with_config_support.py` showing this:
```python
unwrapped_model = accelerator.unwrap_model(model)
# New Code #
# Saves the whole/unpartitioned fp16 model when in ZeRO Stage-3 to the output directory if
# `stage3_gather_16bit_weights_on_model_save` is True in DeepSpeed Config file or
# `zero3_save_16bit_model` is True in DeepSpeed Plugin.
# For Zero Stages 1 and 2, models are saved as usual in the output directory.
# The model name saved is `pytorch_model.bin`
unwrapped_model.save_pretrained(
args.output_dir,
is_main_process=accelerator.is_main_process,
save_function=accelerator.save,
state_dict=accelerator.get_state_dict(model),
)
```
b. To get 32bit weights, first save the model using `model.save_checkpoint()`.
Below is the snippet from `examples/by_feature/deepspeed_with_config_support.py` showing this:
```python
success = model.save_checkpoint(PATH, ckpt_id, checkpoint_state_dict)
status_msg = f"checkpointing: PATH={PATH}, ckpt_id={ckpt_id}"
if success:
logging.info(f"Success {status_msg}")
else:
logging.warning(f"Failure {status_msg}")
```
This will create ZeRO model and optimizer partitions along with `zero_to_fp32.py` script in checkpoint directory.
You can use this script to do offline consolidation.
It requires no configuration files or GPUs. Here is an example of its usage:
```bash
$ cd /path/to/checkpoint_dir
$ ./zero_to_fp32.py . pytorch_model.bin
Processing zero checkpoint at global_step1
Detected checkpoint of type zero stage 3, world_size: 2
Saving fp32 state dict to pytorch_model.bin (total_numel=60506624)
```
To get 32bit model for saving/inference, you can perform:
```python
from deepspeed.utils.zero_to_fp32 import load_state_dict_from_zero_checkpoint
unwrapped_model = accelerator.unwrap_model(model)
fp32_model = load_state_dict_from_zero_checkpoint(unwrapped_model, checkpoint_dir)
```
If you are only interested in the `state_dict`, you can do the following:
```python
from deepspeed.utils.zero_to_fp32 import get_fp32_state_dict_from_zero_checkpoint
state_dict = get_fp32_state_dict_from_zero_checkpoint(checkpoint_dir)
```
Note that all these functions require ~2x memory (general RAM) of the size of the final checkpoint.
## ZeRO Inference
DeepSpeed ZeRO Inference supports ZeRO stage 3 with ZeRO-Infinity.
It uses the same ZeRO protocol as training, but it doesn't use an optimizer and a lr scheduler and only stage 3 is relevant.
With accelerate integration, you just need to prepare the model and dataloader as shown below:
```python
model, eval_dataloader = accelerator.prepare(model, eval_dataloader)
```
## Few caveats to be aware of
1. Current integration doesn’t support Pipeline Parallelism of DeepSpeed.
2. Current integration doesn’t support `mpu`, limiting the tensor parallelism which is supported in Megatron-LM.
3. Current integration doesn’t support multiple models.

# What are these scripts?
All scripts in this folder originate from the `nlp_example.py` file, as it is a very simplistic NLP training example using Accelerate with zero extra features.
From there, each further script adds in just **one** feature of Accelerate, showing how you can quickly modify your own scripts to implement these capabilities.
A full example with all of these parts integrated together can be found in the `complete_nlp_example.py` script and `complete_cv_example.py` script.
Adjustments to each script from the base `nlp_example.py` file can be found quickly by searching for "# New Code #"
## Example Scripts by Feature and their Arguments
### Base Example (`../nlp_example.py`)
- Shows how to use `Accelerator` in an extremely simplistic PyTorch training loop
- Arguments available:
- `mixed_precision`, whether to use mixed precision. ("no", "fp16", or "bf16")
- `cpu`, whether to train using only the CPU. (yes/no/1/0)
All following scripts also accept these arguments in addition to their added ones.
These arguments should be added at the end of any method for starting the python script (such as `python`, `accelerate launch`, `python -m torch.distributed.run`), such as:
```bash
accelerate launch ../nlp_example.py --mixed_precision fp16 --cpu 0
```
### Checkpointing and Resuming Training (`checkpointing.py`)
- Shows how to use `Accelerator.save_state` and `Accelerator.load_state` to save or continue training
- **It is assumed you are continuing off the same training script**
- Arguments available:
- `checkpointing_steps`, after how many steps the various states should be saved. ("epoch", 1, 2, ...)
- `output_dir`, where saved state folders should be saved to, default is current working directory
- `resume_from_checkpoint`, what checkpoint folder to resume from. ("epoch_0", "step_22", ...)
These arguments should be added at the end of any method for starting the python script (such as `python`, `accelerate launch`, `python -m torchrun`), such as:
(Note, `resume_from_checkpoint` assumes that we've ran the script for one epoch with the `--checkpointing_steps epoch` flag)
```bash
accelerate launch ./checkpointing.py --checkpointing_steps epoch output_dir "checkpointing_tutorial" --resume_from_checkpoint "checkpointing_tutorial/epoch_0"
```
### Cross Validation (`cross_validation.py`)
- Shows how to use `Accelerator.free_memory` and run cross validation efficiently with `datasets`.
- Arguments available:
- `num_folds`, the number of folds the training dataset should be split into.
These arguments should be added at the end of any method for starting the python script (such as `python`, `accelerate launch`, `python -m torchrun`), such as:
```bash
accelerate launch ./cross_validation.py --num_folds 2
```
### Experiment Tracking (`tracking.py`)
- Shows how to use `Accelerate.init_trackers` and `Accelerator.log`
- Can be used with Weights and Biases, TensorBoard, or CometML.
- Arguments available:
- `with_tracking`, whether to load in all available experiment trackers from the environment.
These arguments should be added at the end of any method for starting the python script (such as `python`, `accelerate launch`, `python -m torchrun`), such as:
```bash
accelerate launch ./tracking.py --with_tracking
```
### Gradient Accumulation (`gradient_accumulation.py`)
- Shows how to use `Accelerator.no_sync` to prevent gradient averaging in a distributed setup.
- Arguments available:
- `gradient_accumulation_steps`, the number of steps to perform before the gradients are accumulated and the optimizer and scheduler are stepped + zero_grad
These arguments should be added at the end of any method for starting the python script (such as `python`, `accelerate launch`, `python -m torchrun`), such as:
```bash
accelerate launch ./gradient_accumulation.py --gradient_accumulation_steps 5
```
### LocalSGD (`local_sgd.py`)
- Shows how to use `Accelerator.no_sync` to prevent gradient averaging in a distributed setup. However, unlike gradient accumulation, this method does not change the effective batch size. Local SGD can be combined with gradient accumulation.
These arguments should be added at the end of any method for starting the python script (such as `python`, `accelerate launch`, `python -m torchrun`), such as:
```bash
accelerate launch ./local_sgd.py --local_sgd_steps 4
```

# This is a fully working simple example to use Accelerate
#
# This example trains a ResNet50 on the Oxford-IIT Pet Dataset
# in any of the following settings (with the same script):
# - single CPU or single GPU
# - multi GPUS (using PyTorch distributed mode)
# - (multi) TPUs
# - fp16 (mixed-precision) or fp32 (normal precision)
#
# To run it in each of these various modes, follow the instructions
# in the readme for examples:

To use this function absolutely zero calls to a CUDA device must be made in the notebook session before calling. If

# How 🤗 Accelerate runs very large models thanks to PyTorch
## Load and run large models
Meta AI and BigScience recently open-sourced very large language models which won't fit into memory (RAM or GPU) of most consumer hardware. At Hugging Face, part of our mission is to make even those large models accessible, so we developed tools to allow you to run those models even if you don't own a supercomputer. All the examples picked in this blog post run on a free Colab instance (with limited RAM and disk space) if you have access to more disk space, don't hesitate to pick larger checkpoints.
Here is how we can run OPT-6.7B:
```python
import torch
from transformers import pipeline
# This works on a base Colab instance.
# Pick a larger checkpoint if you have time to wait and enough disk space!
checkpoint = "facebook/opt-6.7b"
generator = pipeline("text-generation", model=checkpoint, device_map="auto", torch_dtype=torch.float16)
# Perform inference
generator("More and more large language models are opensourced so Hugging Face has")
```
We'll explain what each of those arguments do in a moment, but first just consider the traditional model loading pipeline in PyTorch: it usually consists of:
1. Create the model
2. Load in memory its weights (in an object usually called `state_dict`)
3. Load those weights in the created model
4. Move the model on the device for inference
While that has worked pretty well in the past years, very large models make this approach challenging. Here the model picked has 6.7 *billion* parameters. In the default precision, it means that just step 1 (creating the model) will take roughly **26.8GB** in RAM (1 parameter in float32 takes 4 bytes in memory). This can't even fit in the RAM you get on Colab.
Then step 2 will load in memory a second copy of the model (so another 26.8GB in RAM in default precision). If you were trying to load the largest models, for example BLOOM or OPT-176B (which both have 176 billion parameters), like this, you would need 1.4 **terabytes** of CPU RAM. That is a bit excessive! And all of this to just move the model on one (or several) GPU(s) at step 4.
Clearly we need something smarter. In this blog post, we'll explain how Accelerate leverages PyTorch features to load and run inference with very large models, even if they don't fit in RAM or one GPU. In a nutshell, it changes the process above like this:
1. Create an empty (e.g. without weights) model
2. Decide where each layer is going to go (when multiple devices are available)
3. Load in memory parts of its weights
4. Load those weights in the empty model
5. Move the weights on the device for inference
6. Repeat from step 3 for the next weights until all the weights are loaded
## Creating an empty model
PyTorch 1.9 introduced a new kind of device called the *meta* device. This allows us to create tensor without any data attached to them: a tensor on the meta device only needs a shape. As long as you are on the meta device, you can thus create arbitrarily large tensors without having to worry about CPU (or GPU) RAM.
For instance, the following code will crash on Colab:
```python
import torch
large_tensor = torch.randn(100000, 100000)
```
as this large tensor requires `4 * 10**10` bytes (the default precision is FP32, so each element of the tensor takes 4 bytes) thus 40GB of RAM. The same on the meta device works just fine however:
```python
import torch
large_tensor = torch.randn(100000, 100000, device="meta")
```
If you try to display this tensor, here is what PyTorch will print:
```
tensor(..., device='meta', size=(100000, 100000))
```
As we said before, there is no data associated with this tensor, just a shape.
You can instantiate a model directly on the meta device:
```python
large_model = torch.nn.Linear(100000, 100000, device="meta")
```
But for an existing model, this syntax would require you to rewrite all your modeling code so that each submodule accepts and passes along a `device` keyword argument. Since this was impractical for the 150 models of the Transformers library, we developed a context manager that will instantiate an empty model for you.
Here is how you can instantiate an empty version of BLOOM:
```python
from accelerate import init_empty_weights
from transformers import AutoConfig, AutoModelForCausalLM
config = AutoConfig.from_pretrained("bigscience/bloom")
with init_empty_weights():
model = AutoModelForCausalLM.from_config(config)
```
This works on any model, but you get back a shell you can't use directly: some operations are implemented for the meta device, but not all yet. Here for instance, you can use the `large_model` defined above with an input, but not the BLOOM model. Even when using it, the output will be a tensor of the meta device, so you will get the shape of the result, but nothing more.
As further work on this, the PyTorch team is working on a new [class `FakeTensor`](https://pytorch.org/torchdistx/latest/fake_tensor.html), which is a bit like tensors on the meta device, but with the device information (on top of shape and dtype)
Since we know the shape of each weight, we can however know how much memory they will all consume once we load the pretrained tensors fully. Therefore, we can make a decision on how to split our model across CPUs and GPUs.
## Computing a device map
Before we start loading the pretrained weights, we will need to know where we want to put them. This way we can free the CPU RAM each time we have put a weight in its right place. This can be done with the empty model on the meta device, since we only need to know the shape of each tensor and its dtype to compute how much space it will take in memory.
Accelerate provides a function to automatically determine a *device map* from an empty model. It will try to maximize the use of all available GPUs, then CPU RAM, and finally flag the weights that don't fit for disk offload. Let's have a look using [OPT-13b](https://huggingface.co/facebook/opt-13b).
```python
from accelerate import infer_auto_device_map, init_empty_weights
from transformers import AutoConfig, AutoModelForCausalLM
config = AutoConfig.from_pretrained("facebook/opt-13b")
with init_empty_weights():
model = AutoModelForCausalLM.from_config(config)
device_map = infer_auto_device_map(model)
```
This will return a dictionary mapping modules or weights to a device. On a machine with one Titan RTX for instance, we get the following:
```python out
{'model.decoder.embed_tokens': 0,
'model.decoder.embed_positions': 0,
'model.decoder.final_layer_norm': 0,
'model.decoder.layers.0': 0,
'model.decoder.layers.1': 0,
...
'model.decoder.layers.9': 0,
'model.decoder.layers.10.self_attn': 0,
'model.decoder.layers.10.activation_fn': 0,
'model.decoder.layers.10.self_attn_layer_norm': 0,
'model.decoder.layers.10.fc1': 'cpu',
'model.decoder.layers.10.fc2': 'cpu',
'model.decoder.layers.10.final_layer_norm': 'cpu',
'model.decoder.layers.11': 'cpu',
...
'model.decoder.layers.17': 'cpu',
'model.decoder.layers.18.self_attn': 'cpu',
'model.decoder.layers.18.activation_fn': 'cpu',
'model.decoder.layers.18.self_attn_layer_norm': 'cpu',
'model.decoder.layers.18.fc1': 'disk',
'model.decoder.layers.18.fc2': 'disk',
'model.decoder.layers.18.final_layer_norm': 'disk',
'model.decoder.layers.19': 'disk',
...
'model.decoder.layers.39': 'disk',
'lm_head': 'disk'}
```
Accelerate evaluated that the embeddings and the decoder up until the 9th block could all fit on the GPU (device 0), then part of the 10th block needs to be on the CPU, as well as the following weights until the 17th layer. Then the 18th layer is split between the CPU and the disk and the following layers must all be offloaded to disk
Actually using this device map later on won't work, because the layers composing this model have residual connections (where the input of the block is added to the output of the block) so all of a given layer should be on the same device. We can indicate this to Accelerate by passing a list of module names that shouldn't be split with the `no_split_module_classes` keyword argument:
```python
device_map = infer_auto_device_map(model, no_split_module_classes=["OPTDecoderLayer"])
```
This will then return
```python out
'model.decoder.embed_tokens': 0,
'model.decoder.embed_positions': 0,
'model.decoder.final_layer_norm': 0,
'model.decoder.layers.0': 0,
'model.decoder.layers.1': 0,
...
'model.decoder.layers.9': 0,
'model.decoder.layers.10': 'cpu',
'model.decoder.layers.11': 'cpu',
...
'model.decoder.layers.17': 'cpu',
'model.decoder.layers.18': 'disk',
...
'model.decoder.layers.39': 'disk',
'lm_head': 'disk'}
```
Now, each layer is always on the same device.
In Transformers, when using `device_map` in the `from_pretrained()` method or in a `pipeline`, those classes of blocks to leave on the same device are automatically provided, so you don't need to worry about them. Note that you have the following options for `device_map` (only relevant when you have more than one GPU):
- `"auto"` or `"balanced"`: Accelerate will split the weights so that each GPU is used equally;
- `"balanced_low_0"`: Accelerate will split the weights so that each GPU is used equally except the first one, where it will try to have as little weights as possible (useful when you want to work with the outputs of the model on one GPU, for instance when using the `generate` function);
- `"sequential"`: Accelerate will fill the GPUs in order (so the last ones might not be used at all).
You can also pass your own `device_map` as long as it follows the format we saw before (dictionary layer/module names to device).
Finally, note that the results of the `device_map` you receive depend on the selected dtype (as different types of floats take a different amount of space). Providing `dtype="float16"` will give us different results:
```python
device_map = infer_auto_device_map(model, no_split_module_classes=["OPTDecoderLayer"], dtype="float16")
```
In this precision, we can fit the model up to layer 21 on the GPU:
```python out
{'model.decoder.embed_tokens': 0,
'model.decoder.embed_positions': 0,
'model.decoder.final_layer_norm': 0,
'model.decoder.layers.0': 0,
'model.decoder.layers.1': 0,
...
'model.decoder.layers.21': 0,
'model.decoder.layers.22': 'cpu',
...
'model.decoder.layers.37': 'cpu',
'model.decoder.layers.38': 'disk',
'model.decoder.layers.39': 'disk',
'lm_head': 'disk'}
```
Now that we know where each weight is supposed to go, we can progressively load the pretrained weights inside the model.
## Sharding state dicts
Traditionally, PyTorch models are saved in a whole file containing a map from parameter name to weight. This map is often called a `state_dict`. Here is an excerpt from the [PyTorch documentation](https://pytorch.org/tutorials/beginner/basics/saveloadrun_tutorial.html) on saving on loading:
```python
# Save the model weights
torch.save(my_model.state_dict(), 'model_weights.pth')
# Reload them
new_model = ModelClass()
new_model.load_state_dict(torch.load('model_weights.pth'))
```
This works pretty well for models with less than 1 billion parameters, but for larger models, this is very taxing in RAM. The BLOOM model has 176 billions parameters; even with the weights saved in bfloat16 to save space, it still represents 352GB as a whole. While the super computer that trained this model might have this amount of memory available, requiring this for inference is unrealistic.
This is why large models on the Hugging Face Hub are not saved and shared with one big file containing all the weights, but **several** of them. If you go to the [BLOOM model page](https://huggingface.co/bigscience/bloom/tree/main) for instance, you will see there is 72 files named `pytorch_model_xxxxx-of-00072.bin`, which each contain part of the model weights. Using this format, we can load one part of the state dict in memory, put the weights inside the model, move them on the right device, then discard this state dict part before going to the next. Instead of requiring to have enough RAM to accommodate the whole model, we only need enough RAM to get the biggest checkpoint part, which we call a **shard**, so 7.19GB in the case of BLOOM.
We call the checkpoints saved in several files like BLOOM *sharded checkpoints*, and we have standardized their format as such:
- One file (called `pytorch_model.bin.index.json`) contains some metadata and a map parameter name to file name, indicating where to find each weight
- All the other files are standard PyTorch state dicts, they just contain a part of the model instead of the whole one. You can have a look at the content of the index file [here](https://huggingface.co/bigscience/bloom/blob/main/pytorch_model.bin.index.json).
To load such a sharded checkpoint into a model, we just need to loop over the various shards. Accelerate provides a function called `load_checkpoint_in_model` that will do this for you if you have cloned one of the repos of the Hub, or you can directly use the `from_pretrained` method of Transformers, which will handle the downloading and caching for you:
```python
import torch
from transformers import AutoModelForCausalLM
# Will error
checkpoint = "facebook/opt-13b"
model = AutoModelForCausalLM.from_pretrained(checkpoint, device_map="auto", torch_dtype=torch.float16)
```
If the device map computed automatically requires some weights to be offloaded on disk because you don't have enough GPU and CPU RAM, you will get an error indicating you need to pass an folder where the weights that should be stored on disk will be offloaded:
```python out
ValueError: The current `device_map` had weights offloaded to the disk. Please provide an
`offload_folder` for them.
```
Adding this argument should resolve the error:
```python
import torch
from transformers import AutoModelForCausalLM
# Will go out of RAM on Colab
checkpoint = "facebook/opt-13b"
model = AutoModelForCausalLM.from_pretrained(
checkpoint, device_map="auto", offload_folder="offload", torch_dtype=torch.float16
)
```
Note that if you are trying to load a very large model that require some disk offload on top of CPU offload, you might run out of RAM when the last shards of the checkpoint are loaded, since there is the part of the model staying on CPU taking space. If that is the case, use the option `offload_state_dict=True` to temporarily offload the part of the model staying on CPU while the weights are all loaded, and reload it in RAM once all the weights have been processed
```python
import torch
from transformers import AutoModelForCausalLM
checkpoint = "facebook/opt-13b"
model = AutoModelForCausalLM.from_pretrained(
checkpoint, device_map="auto", offload_folder="offload", offload_state_dict = True, torch_dtype=torch.float16
)
```
This will fit in Colab, but will be so close to using all the RAM available that it will go out of RAM when you try to generate a prediction. To get a model we can use, we need to offload one more layer on the disk. We can do so by taking the `device_map` computed in the previous section, adapting it a bit, then passing it to the `from_pretrained` call:
```python
import torch
from transformers import AutoModelForCausalLM
checkpoint = "facebook/opt-13b"
device_map["model.decoder.layers.37"] = "disk"
model = AutoModelForCausalLM.from_pretrained(
checkpoint, device_map=device_map, offload_folder="offload", offload_state_dict = True, torch_dtype=torch.float16
)
```
## Running a model split on several devices
One last part we haven't touched is how Accelerate enables your model to run with its weight spread across several GPUs, CPU RAM, and the disk folder. This is done very simply using hooks.
> [hooks](https://pytorch.org/docs/stable/generated/torch.nn.Module.html#torch.nn.Module.register_forward_hook) are a PyTorch API that adds functions executed just before each forward called
We couldn't use this directly since they only support models with regular arguments and no keyword arguments in their forward pass, but we took the same idea. Once the model is loaded, the `dispatch_model` function will add hooks to every module and submodule that are executed before and after each forward pass. They will:
- make sure all the inputs of the module are on the same device as the weights;
- if the weights have been offloaded to the CPU, move them to GPU 0 before the forward pass and back to the CPU just after;
- if the weights have been offloaded to disk, load them in RAM then on the GPU 0 before the forward pass and free this memory just after.
The whole process is summarized in the following video:
<iframe width="560" height="315" src="https://www.youtube.com/embed/MWCSGj9jEAo" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
This way, your model can be loaded and run even if you don't have enough GPU RAM and CPU RAM. The only thing you need is disk space (and lots of patience!) While this solution is pretty naive if you have multiple GPUs (there is no clever pipeline parallelism involved, just using the GPUs sequentially) it still yields [pretty decent results for BLOOM](https://huggingface.co/blog/bloom-inference-pytorch-scripts). And it allows you to run the model on smaller setups (albeit more slowly).

# TTS Arena: Benchmarking Text-to-Speech Models in the Wild
Automated measurement of the quality of text-to-speech (TTS) models is very difficult. Assessing the naturalness and inflection of a voice is a trivial task for humans, but it is much more difficult for AI. This is why today, we’re thrilled to announce the TTS Arena. Inspired by [LMSys](https://lmsys.org/)'s [Chatbot Arena](https://huggingface.co/spaces/lmsys/chatbot-arena-leaderboard) for LLMs, we developed a tool that allows anyone to easily compare TTS models side-by-side. Just submit some text, listen to two different models speak it out, and vote on which model you think is the best. The results will be organized into a leaderboard that displays the community’s highest-rated models.

<gradio-app theme_mode="light" space="TTS-AGI/TTS-Arena"></gradio-app>
## Motivation
The field of speech synthesis has long lacked an accurate method to measure the quality of different models. Objective metrics like WER (word error rate) are unreliable measures of model quality, and subjective measures such as MOS (mean opinion score) are typically small-scale experiments conducted with few listeners. As a result, these measurements are generally not useful for comparing two models of roughly similar quality. To address these drawbacks, we are inviting the community to rank models in an easy-to-use interface. By opening this tool and disseminating results to the public, we aim to democratize how models are ranked and to make model comparison and selection accessible to everyone.
## The TTS Arena
Human ranking for AI systems is not a novel approach. Recently, LMSys applied this method in their [Chatbot Arena](https://arena.lmsys.org/) with great results, collecting over 300,000 rankings so far. Because of its success, we adopted a similar framework for our leaderboard, inviting any person to rank synthesized audio.
The leaderboard allows a user to enter text, which will be synthesized by two models. After listening to each sample, the user will vote on which model sounds more natural. Due to the risks of human bias and abuse, model names will be revealed only after a vote is submitted.
## Selected Models
We selected several SOTA (State of the Art) models for our leaderboard. While most are open-source models, we also included several proprietary models to allow developers to compare the state of open-source development with proprietary models.
The models available at launch are:
- ElevenLabs (proprietary)
- MetaVoice
- OpenVoice
- Pheme
- WhisperSpeech
- XTTS
Although there are many other open and closed source models available, we chose these because they are generally accepted as the highest-quality publicly available models.
## The TTS Leaderboard
The results from Arena voting will be made publicly available in a dedicated leaderboard. Note that it will be initially empty until sufficient votes are accumulated, then models will gradually appear. As raters submit new votes, the leaderboard will automatically update.
Similar to the Chatbot Arena, models will be ranked using an algorithm similar to the [Elo rating system](https://en.wikipedia.org/wiki/Elo_rating_system), commonly used in chess and other games.
## Conclusion
We hope the [TTS Arena](https://huggingface.co/spaces/TTS-AGI/TTS-Arena) proves to be a helpful resource for all developers. We'd love to hear your feedback! Please do not hesitate to let us know if you have any questions or suggestions by sending us an [X/Twitter DM](https://twitter.com/realmrfakename), or by opening a discussion in [the community tab of the Space](https://huggingface.co/spaces/TTS-AGI/TTS-Arena/discussions).

# Some Notes on Pros of Open Science and Open Source
- **Pooling Resources**: Building off of one another’s strengths; learning from one another’s failures.
- **Accessibility**: Anyone can use the models, regardless of budget or affiliation.
- This also helps to ensure diversity of contributors.
- **Lowering Barriers**: You don’t need to have a tech job to explore how AI works.
- **Innovation**: High-value applications are possible for more people to discover and create.
- Relatedly, advancements in **addressing bias/harms** become more possible.
- **Economic Opportunity**: More access leads to more businesses and jobs.
- **Transparency**: Users and those affected have full visibility on the model and the training data. They can better identify potential biases or errors.
- **Accountability**: Provenance to trace who-did-what; independent auditing possible.
- **Privacy**: Users don't have to send their data to black box APIs.
- **IP protection**: Users train their models on their data, and own them.
- **Freedom of choice**: Users are not locked in. They can switch models anytime.
- **IT flexibility**: Users can train and deploy models anywhere they like.
- **Tailored use**: Users can train/fine-tune for their specific needs.
- **Safety**: More mechanisms available.
- **Speed**: Good ideas can quickly flourish and be built on. Security issues can be quickly addressed.
- **Diversity** of options.
# Cons of Closed Source
- **Centralization** of power.
- **Opacity** of subtle bias/harm issues.
- Hiding **illegal** or problematic data.
- **Bare minimum of legal compliance** as opposed to good practices.
- Fostering **misunderstanding for hype and profit**.
- **Insularity of thinking** creates "groupthink" technology issues (such as harming people with marginalized characteristics).
- **Security issues** not addressed quickly.
- Consumer apps **can’t be flexible** and become dependent on a single model: Consumer apps built on top of closed source must “lock-in” their code based on what an API outputs; as closed source internal models are updated or changed, this can completely break the consumer’s system, or the consumer’s expectations of behavior.
# Common Misunderstandings
## There’s an idea that open source is “less secure”.
- Misses that closed software has just as dire (or more so) security concerns as open source.
- Misses the fact that the diversity of options available with open source limits how many people will be affected by a malicious actor.
## There’s an idea that open source will help China to “beat us”.
- Misses that part of why U.S. technology has flourished due to open science/open source.
- Misses that U.S. dominance is a function of how friendly the U.S. is to companies: There is more to success than the code itself, the socioeconomic variables that the U.S. provides is particularly well-placed to help open companies flourish.
