      distributed FSDP model initialization · abdad994
      Geet Sethi authored 
      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/656

Enable distributed FSDP model initialization. This iteratively moves and shards the model on GPU to allow for the training of models greater than single GPU HBM capacity and which cannot be instantiated multiple times on a single host.

The flow is as follows:
1. Rank 0 will init the whole model on CPU using existing code paths, while all other ranks init an 'empty' model using fake tensors.
2. Once this is complete and initialization moves to FSDP, distributed init will traverse the model 'bottom-up', transferring all params/buffers from rank 0 to all other ranks, while simultaneously wrapping modules in FSDP whenever possible (based on the specified config). Thus modules are sharded (and memory usage distributed) at the first possible instance using the existing FSDP api/implementation.

      ensure metadata thing_classes consistency with multiple datasets and category filtering · 1216c225
      Zhicheng Yan authored 
      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/653

# Changes
In Mask2Former RC4 training, we need to use a particular weighted category training sampler where `DATALOADER.SAMPLER_TRAIN = "WeightedCategoryTrainingSampler"`.

Also there are multiple datasets are used, and the set of each one's categories are not exactly identical. Some datasets have more categories (e.g. Exo-body) than other datasets that do not have exobody annotations.

Also we use category filtering by setting `D2GO_DATA.DATASETS.TRAIN_CATEGORIES` to a subset of full categories.

In this setup, currently D2GO will complain metadata.thing_classes is NOT consistency across datasets (https://fburl.com/code/k8xbvyfd).

The reason is when category filtering is used, D2GO writes a temporary dataset json file (https://fburl.com/code/slb5z6mc).
And this tmp json file will be loaded when we get the dataset dicts from DatasetCatalog (https://fburl.com/code/5k4ynyhc). Meanwhile, metadata in MetadataCatalog for this category-filtered dataset is also updated based on categories stored in this tmp file.

Therefore, we must ensure categories stored in the tmp file is consistent between multiple category-filtered datasets.

In this diff, we update the logic of writing such tmp dataset json file.

# Github CI test
Note **CI / python-unittest-cpu** is shown as failed with error below. But I do not think it is related to changes in this diff since error is related to observer in the QAT model training, but changes in the diff are related to dataset preparation.

      expose example_input argument in setup_qat_model() · 3c6f71b4
      Zhicheng Yan authored 
      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/647

Major changes
- **example_input** argument in **prepare_fake_quant_model()** is useful in certain cases. For example, in Argos model **custom_prepare_fx()** method under FX graph + QAT setup (D52760682), it is used to prepare example inputs to individual sub-modules by running one forward pass and bookkeeping the inputs to individual sub-modules. Therefore, we export argument **example_input** in **setup_qat_model()** function.
- For QAT model, currently we assert # of state dict keys (excluding observers) should be equal to # of state dict keys in the original model. However, when the assertion fails, it does not log useful information for debugging. We make changes to report what are the unique keys in each state dict.

      Kapil Krishnakumar authored 
      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/644

This diff consolidates deterministic settings in D2Go. In the `default_runner.py` file, the `torch.set_float32_matmul_precision("highest")` function is added to set the precision for matrix multiplication to the highest possible value. In the `setup.py` file, the `torch.backends.cudnn.deterministic` setting is set to `True` and the `torch.backends.cudnn.allow_tf32` setting is set to `False` to avoid random pytorch and CUDA algorithms during the training. The `torch.backends.cuda.matmul.allow_tf32` setting is also set to `False` to avoid random matrix multiplication algorithms. Additionally, the `seed` function is used to set the seed for reproducibility.

      allow to ignore state dict keys in QAT model · c2256758
      Zhicheng Yan authored 
      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/642

When we build a QAT model using FX graph mode API **prepare_qat_fx** and **convert_fx**, they will run symbolic tracing following **module.forward()**.

In certain cases, such as a module takes constant tensor input, the symbolic tracing will add new tensor attributes with name prefix **_tensor_constant** (https://fburl.com/code/msc4ch4o), which becomes new keys in the QAT model state dict.

In current implementation of **_setup_non_qat_to_qat_state_dict_map**, it asserts # of keys in the state dict of original- and QAT model should be the same.

Thus, we extend **qat_state_dict_keys_to_ignore** method by adding an argument, which allows to ignore specified state dict keys in the QAT model.

      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/643

For a QAT model, it contains observers. After QAT training, those observers already contain updated statistics, such as min_val, max_val.

When we want to export FP32 QAT model for a sanity check, if we call **fuse_utils.fuse_model()** again (which is often already called when we build the QAT model before QAT training), it will remove statistics in the observers.

      Zhicheng Yan authored 
      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/630

Currently, in runner **build_model()** method, when **eval_only=True**, we always try to load model weights.
This is quite restricted in some cases. For example, we may just wanna build a model in eval mode to profile its efficiency, and we have not trained the model or generated the model weights in a checkpoint file.

Thus, this diff adds an argument **skip_model_weights** to allow users to skip the loading of model weights.
Note, this diff is entirely back-compatible and is NOT expected to break existing implementations.

      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/627

Enable training for fraction of total steps: when doing HPO, users may want to train for a fraction of the number of training steps of a regular (baseline) training run. In this case, it is not enough to just change SOLVER.MAX_ITER because that also changes the learning rate schedule. We introduce a multiplier to be used on top of SOLVER.MAX_ITER when deciding how many steps to train for. This multiplier does not scale the number of steps over which the learning rate schedule is defined.

      Make EMA checkpointing with FSDP more robust · 477629d0
      Anthony Chen authored 
      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/615

Previous FSDP EMA checkpointing logic directly handles `EMAState`: it manually calls `FSDP.summon_full_params()` to gather the full model params, and reconstruct/load an `EMAState` for checkpointing. This logic has two drawbacks:

1. `FSDP.summon_full_params()` gathers all model weights at the same time, which could cause OOM issues if the model can't fit into a single GPU. This is quite common for FSDP workloads.
2.  Directly saving and loading `EMAState` is error-prone. EMA state dict has different semantics and behaviors than `model.state_dict()`. However, users often expect it to function seamlessly like the model state dict

This diff modifies the save/load logic of EMA to directly use `model.state_dict()` to solve the above 2 painpoints

      Propagate include_frozen/buffers to EMAState in FSDP FULL_STATE_DICT checkpoints · 206a05c6
      Ed Pizzi authored 
      Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/620

EMA can be configured to exclude frozen (`requires_grad=False`) parameters and buffers, reducing memory use and checkpoint size.

However `FULL_STATE_DICT` FSDP + EMA checkpoints construct an inner `EMAState` after unsharding FSDP parameters. This inner `EMAState` uses default `include_frozen` and `include_buffers` settings, resulting in checkpoints containing frozen parameters and buffers regardless of settings.

Propagate `include_frozen` and `include_buffers` settings to the inner `EMAState` when gathering `FULL_STATE_DICT` FSDP EMA state.

This change only affects frozen parameters with a parallel fix to PyTorch FSDP to propagate `requires_grad` across parameter sharding/unsharding: https://github.com/pytorch/pytorch/pull/109892.
