corrected files

changed to FedProxOptimizer and ran set_old_weights for new FedProx Pytorch example

renamed FedProx notebook

used mode.parrameters() to get pytorch model weights

got weights using state_dict

changed old wieghts to list (for serialization) and fixed README

input wieghts before zero_grad

This adds a new tutorial example on distributing a linear regression task over OpenFL cluster.

    The model is defined by Pytorch which is able to run over both cpu (by default) and gpu. The dataset is generated by make_regression from sklearn.datasets with pre-defined parameters.

This update:
1. Restores Roboto and Lato fonts for most body copy, leaving Intel One Mono for code samples.
2. Adds colors (in `colors.css`)
3. Adds a new `accessibility_overrides.css` file containing CSS that improves the accessibility of the documentation and, where possible, Read The Docs. These updates remediate numerous non-conforming WCAG 2.x Level AA bugs. The use of a separate file for this hopefully makes these changes easier to manage and less likely to be accessibility overwritten in the future.

# This is equivalent to:
# local_runtime = LocalRuntime(aggregator=aggregator, collaborators=collaborators, backend='single_process')
local_runtime = LocalRuntime(aggregator=aggregator, collaborators=collaborators)
Let's break this down, starting with the :code:`Aggregator` and :code:`Collaborator` placeholders. These placeholders represent the nodes where tasks will be executed. Each participant placeholder has its own set of :code:`private_attributes`; a dictionary where the key is the name of the attribute, and the value is the object. In the above example, each of the four collaborators ('Portland', 'Seattle', 'Chandler', and 'Bangalore'), have a :code:`train_loader` and `test_loader` that they can access. These private attributes can be named anything, and do not necessarily need to be the same across each participant.
# Setup collaborators private attributes via callable function
collaborators = []
for idx, collaborator_name in enumerate(collaborator_names):
collaborators.append(
Collaborator(
name=collaborator_name,
private_attributes_callable=callable_to_initialize_collaborator_private_attributes,
index=idx,
n_collaborators=len(collaborator_names),
train_dataset=mnist_train,
test_dataset=mnist_test,
batch_size=64
)
)
local_runtime = LocalRuntime(aggregator=aggregator_, collaborators=collaborators)
Let's break this down, starting with the :code:`Aggregator` and :code:`Collaborator` components. These components represent the *Participants* in a Federated Learning experiment. Each participant has its own set of *private attributes* that represent the information / data specific to its role or requirements. As the name suggests these *private attributes* are accessible only to the particular participant, and are appropriately inserted into or filtered out of current Flow state when transferring from between Participants. For e.g. Collaborator private attributes are inserted into :code:`flow` when transitioning from Aggregator to Collaborator and are filtered out when transitioning from Collaborator to Aggregator.

In the above :code:`FederatedFlow`, each collaborator accesses train and test datasets via *private attributes* :code:`train_loader` and :code:`test_loader`. These *private attributes* need to be set using a (user defined) callback function while instantiating the participant. Participant *private attributes* are returned by the callback function in form of a dictionary, where the key is the name of the attribute and the value is the object.

In this example callback function :code:`callable_to_initialize_collaborator_private_attributes()` returns the collaborator private attributes :code:`train_loader` and :code:`test_loader` that are accessed by collaborator steps (:code:`aggregated_model_validation`, :code:`train` and :code:`local_model_validation`). Some important points to remember while creating callback function and private attributes are:

- Callback Function needs to be defined by the user and should return the *private attributes* required by the participant in form of a key/value pair
- In above example multiple collaborators have the same callback function. Depending on the Federated Learning requirements, user can specify unique callback functions for each Participant
- If no Callback Function is specified then the Participant shall not have any *private attributes*
- Callback function can be provided with any parameters required as arguments. In this example, parameters essential for the callback function are supplied with corresponding values bearing *same names* during the instantiation of the Collaborator

* :code:`index`: Index of the particular collaborator needed to shard the dataset
* :code:`n_collaborators`: Total number of collaborators in which the dataset is sharded
* :code:`batch_size`: For the train and test loaders
* :code:`train_dataset`: Train Dataset to be sharded between n_collaborators
* :code:`test_dataset`: Test Dataset to be sharded between n_collaborators

- Callback function needs to be specified by user while instantiating the participant. Callback function is invoked by the OpenFL runtime at the time participant is created and once created these attributes cannot be modified
- Private attributes are accessible only in the Participant steps

Now let's see how the runtime for a flow is assigned, and the flow gets run:

Runtime Backends
================

The Runtime defines where code will run, but the Runtime has a :code:`Backend` - which defines the underlying implementation of *how* the flow will be executed. :code:`'single_process'` is the default in the :code:`LocalRuntime`: it executes all code sequentially within a single python process, and is well suited to run both on high spec and low spec hardware. For users with large servers or multiple GPUs they wish to take advantage of, we also provide a `Ray <https://github.com/ray-project/ray>` backend. The Ray backend enables parallel task execution for collaborators, and optionally allows users to request dedicated GPUs for collaborator tasks in the placement decorator, as follows:

For users with large servers or multiple GPUs they wish to take advantage of, we also provide a :code:`ray` `<https://github.com/ray-project/ray>` backend. The Ray backend enables parallel task execution for collaborators, and optionally allows users to request dedicated CPU / GPUs for Participants by using the :code:`num_cpus` and :code:`num_gpus` arguments while instantiating the Participant in following manner:

.. code-block:: python
ExampleDedicatedGPUFlow(FLSpec):
...
# We request one dedicated GPU for this task
@collaborator(num_gpus=1)
def training(self):
print(f'CUDA_VISIBLE_DEVICES: {os.environ["CUDA_VISIBLE_DEVICES"]}'))
self.loss = train_func(self.model, self.train_loader)
self.next(self.validation)
...
# Aggregator
aggregator_ = Aggregator(num_gpus=0.2)
collaborator_names = ["Portland", "Seattle", "Chandler", "Bangalore"]
def callable_to_initialize_collaborator_private_attributes(index, n_collaborators, batch_size, train_dataset, test_dataset):
...
# Setup collaborators private attributes via callable function
collaborators = []
for idx, collaborator_name in enumerate(collaborator_names):
collaborators.append(
Collaborator(
name=collaborator_name,
num_gpus=0.2, # Number of the GPU allocated to Participant
private_attributes_callable=callable_to_initialize_collaborator_private_attributes,
index=idx,
n_collaborators=len(collaborator_names),
train_dataset=mnist_train,
test_dataset=mnist_test,
batch_size=64
)
)
# The Ray Backend will now be used for local execution
local_runtime = LocalRuntime(aggregator=aggregator, collaborators=collaborators, backend='ray')
In the above example, we have used :code:`num_gpus=0.2` while instantiating Aggregator and Collaborator to specify that each participant shall use 1/5th of GPU - this results in one GPU being dedicated for a total of 4 collaborators and 1 Aggregator. Users can tune these arguments based on their Federated Learning requirements and available hardware resources. Configurations where one Participant is shared across GPUs is not supported. For e.g. trying to run 5 participants on 2 GPU hardware with :code:`num_gpus=0.4` will not work since 80% of each GPU is allocated to 4 participants and 5th participant does not have any available GPU remaining for use.

**Note:** It is not necessary to have ALL the participants use GPUs. For e.g. only the Collaborator are allocated to GPUs. In this scenario user should ensure that the artifacts returned by Collaborators to Aggregator (e.g. locally trained model object) should be loaded back to CPU before exiting the collaborator step (i.e. before the join step). As Tensorflow manages the object allocation by default therefore this step is needed only for Pytorch.
