fairseq distributed training

You signed in with another tab or window. Training with fairseq-hydra-train To fully take advantage of configuration flexibility offered by Hydra, you may want to train new models using the fairseq-hydra-train entry point. For future reference, I encountered the same issue with PyTorch 1.5.1 and was sure that I don't have any OOM issues (issue persists at batch_size=1). One of the benets of pre-training is the possibility to use large, unlabeled, and thus relatively inexpen-sive datasets. I was actually referring this documentation. CUDA version: 9.2. """, freewym / espresso / fairseq / trainer.py, "Fatal error: gradients are inconsistent between workers. applications, this became problematic. PDF | Sharpness aware minimization (SAM) optimizer has been extensively explored as it can generalize better for training deep neural networks via. e.g., using Nvidia Tensor Cores. Torch Version: 1.1.0 I'm not sure why it launches 15 processes. using torchrun or something that can work with hydra-train? continuation markers can be removed with the --remove-bpe flag. the value one can use in a YAML config file or through command line to achieve Hydra is an open-source Python It runs normal in single gpu, but get stuck in valid period with multi-gpu. conflict_handler(action, confl_optionals) > curl https://dl.fbaipublicfiles.com/fairseq/models/wmt14.v2.en-fr.fconv-py.tar.bz2 | tar xvjf -, --beam 5 --source-lang en --target-lang fr \, --bpe subword_nmt --bpe-codes $MODEL_DIR/bpecodes, | loading model(s) from wmt14.en-fr.fconv-py/model.pt. This wasn't happening a few weeks ago. I am having the same issue actually? Btw, when you override the distributed_training arguments in fairseq: If key is in yaml, just dokey= in the command line. privacy statement. On 1st node I'm executing the fairseq training command with following distributed training flags: PYTHONPATH=$FAIRSEQPY:$PYTHONPATH CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 python3.6 $FAIRSEQPY/train.py --distributed-world-size 16 --distributed-rank 0 --distributed-backend "nccl" --distributed-init-method 'tcp://54.146.137.72:9001' --distributed-port 9001. on 2nd node I'm executing the fairseq training command with following distributed training flags: PYTHONPATH=$FAIRSEQPY:$PYTHONPATH CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 python3.6 $FAIRSEQPY/train.py --distributed-world-size 16 --distributed-rank 8 --distributed-backend "nccl" --distributed-init-method 'tcp://54.146.137.72:9001' --distributed-port 9001. on second node I got the following error log. components inherit from FairseqTask and FairseqModel and provide a dataclass this are new ARM-based chips made by Fujitsu, having close to GPU compute performance and same memory bandwidths (1TB/s). I have set two NCCL environment flag. For an example of how Following is the command line I am using: The text was updated successfully, but these errors were encountered: pytorch / fairseq related arguments look correct to me, specifically --distributed-world-size, --distributed-rank , --distributed-init-method and --distributed-backend. I'm using following NCCL as backend and along with that I'm using following command to execute the distributed training. Learn how to use python api fairseq.fp16_trainer.FP16Trainer We'll likely add support for distributed CPU training soon, although mostly for CI purposes. Any help is much appreciated. args namespace that was created at application startup. Clear to me now. The --update-freq option can be used to accumulate gradients from The toolkit is based on PyTorch and supports distributed training across multiple GPUs and machines. "read this many sentences into a buffer before processing them". change the number of GPU devices that will be used. Distributed Training. remove the BPE continuation markers and detokenize the output. Already on GitHub? <. File "/srv/home/e/eshaan/fairseq/fairseq_cli/eval_lm.py", line 251, in cli_main Here, we briey describe the three methods with the highest performance. would not clash with arguments from other components. Have a question about this project? Build command you used (if compiling from source): GPU models and configuration: 10 RTX 2080 Ti. node in the same hierarchy: II("optimization.lr") is syntactic sugar for "${optimization.lr}", which is Powered by Discourse, best viewed with JavaScript enabled, Encounter Error while running distributed training on fairseq, https://github.com/pytorch/fairseq/issues/138, Nccl error in torch._C._dist_broadcast(tensor, src, group) when train in two nodes, Multi node distributed training: RuntimeError: NCCL error in /torch/lib/THD/base/data_channels/DataChannelNccl.cpp:322, unhandled system error. argparse.ArgumentError: argument --distributed-world-size: conflicting option string: --distributed-world-size. I have copy of code and data on 2 nodes each node is having 8 GPUs. @ngoyal2707 thanks for the suggestion and I will try this and update my findings here. I think it should be similar as running usual pytorch multi-node applications: , where you need to specify other arguments like HOST_NODE_ADDR. fairseq-interactive (for raw text): To generate translations with only a CPU, use the --cpu flag. "source of truth" (see inheritance example below). to your account, I am trying to run distributed training on 2 nodes with 8 GPUs each (K80) in total 16 GPUs. We are sorry that we haven't been able to prioritize it yet. want to train new models using the fairseq-hydra-train entry point. I wouldn't expect particularly good training throughput on CPU We have a cluster of 100K nodes (yes, a hundred thousands) of A64FX CPUs override is one key we added in the decoding config Some of the most common use cases are shown below: Note that along with explicitly providing values for parameters such as The no_c10d backend is more robust since it only communicates at the end of the backward pass, but there are still limits to this kind of recovery. Pytorch 1.1.0, I have run nccl-test using this command it run perfectly. class fairseq.criterions.adaptive_loss.AdaptiveLoss (task, sentence_avg) . I have set two NCCL environment flag $ export NCCL_SOCKET_IFNAME=ens3 $ export NCCL_DEBUG=INFO On 1st node I'm executing the fairseq training . --nnodes=1 --node_rank=0 --master_addr="10.138.0.6" Python version is 3.6. where /path/to/external/configs has the following structure: and 2_layers.yaml contains a copy of transformer_lm_gpt.yaml but with Other types of output lines you might see are D, the detokenized hypothesis, As an example, we use the WikiText-103 dataset to pretrain the RoBERTa model following this tutorial. (AKA, are models trained with and without c10d equivalent?). If key is not in The no_c10d backend is more robust since it only communicates at the end of the backward pass, but there are still limits to this kind of recovery. examples that others can use to run an identically configured job. Legacy CLI Note that this assumes that there is an "optimization" config Well occasionally send you account related emails. I got it working when I disable all GPUs: Steps to reproduce the behavior (always include the command you ran): The text was updated successfully, but these errors were encountered: By default fairseq tries to use all visible GPUs and will setup distributed training across them. FairseqConfig object. their own add_args method to update the argparse parser, hoping that the names how to do this). Do not forget to modify the import path in the code. File "/home/e/miniconda3/envs/eshaan/lib/python3.6/argparse.py", line 1505, in _check_conflict apply_bpe.py Same error here. Are you confident about ens3 network interface? Reference. examples/ directory. Several things here: 1. rdzv_id should be set to the job id, which is shared by all nodes 2. fairseq-hydra-train should be set to the python file name fairseq/fairseq_cli/hydra_train.py. The script worked in one of our cloud environments, but not in another and I'm trying to figure out why.

GPUs, but a port number must be provided: It can be challenging to train over very large datasets, particularly if your Transformers: State-of-the-art Machine Learning for Pytorch, TensorFlow, and JAX. Top-level configs that should be present in max_positions= 1024, convolutions=((512, 3),) * 20, dropout= 0.1): super ().__init__(dictionary) self.dropout = dropout self.num_attention_layers = None num . I am using the command lines from here and have slightly modified them where I am using a patience of 3, no-epoch-checkpoints, removed fp16, and distributed-world-size of 1 when training. How to use the fairseq.distributed_utils function in fairseq To help you get started, we've selected a few fairseq examples, based on popular ways it is used in public projects. With the invention of deep learning concepts, Machine Translation (MT) migrated towards Neural Machine Translation (NMT) architectures, eventually from Statistical Machine Translation (SMT), which ruled MT for a few decades. Distributed training Distributed training in fairseq is implemented on top of torch.distributed . However, upgrading to PyTorch 1.7.1 solved my issue, so it seems like there are multiple possible causes to this issue and this could be an underlying PyTorch problem, too.

FairseqDataclass (which adds some functionality for backward compatibility). Already on GitHub? Ok - do you also recommend no_c10d on a single GPU? https://fairseq.readthedocs.io/en/latest/getting_started.html#distributed-training Training begins by launching one worker process per GPU. number of tokens per batch (--max-tokens). top-level config file (for example, you might have I am running it on a machine with 8 V100 GPUs. :), Traceback (most recent call last): smaller value depending on the available GPU memory on your system. # Setup task, e.g., translation, language modeling, etc. Are you sure you want to create this branch? But for a single node you can just run fairseq-train directly without torch.distributed.launch -- it will automatically use all visible GPUs on a single node for training. You should not need --distributed-port but that's okay to have. Write a standalone Pytorch DDP training code (examples here: https://pytorch.org/tutorials/intermediate/ddp_tutorial.html), I don't think your issue is in fairseq.

Then you can adapt your training command like so: Training will now iterate over each shard, one by one, with each shard When I run eval_lm with the argument "--distributed-world-size 1" it fails: File "eval_lm.py", line 11, in (2018) for more details. I also changed the paths to reflect my own directory structure. works for migrated tasks and models. sed s/@@ //g or by passing the --remove-bpe You signed in with another tab or window. parameters required to configure this component. Yes @huihuifan , in trainer.py there is the try-catch you are referring to, but what happens to the "troublesome OOMs" in that catch block? return self._add_action(action) The dataclass is registered Unfortunately, I don't think I have slurm installed on our cluster nor do I have a root privilege to configure it. supervised pre-training, and consecutive ne-tuning approach for automatic speech recognition with a transformer network. Since last fairseq versions, during the training of a transformer_vaswani_wmt_en_de_big the process gets stuck, normally after an OOM batch but not necessarily.. Fairseq provides several command-line tools for training and evaluating models: fairseq-preprocess: Data pre-processing: build vocabularies and binarize training data; fairseq-train: Train a new model on one or multiple GPUs; fairseq-generate: Translate pre-processed data with a trained model; fairseq-interactive: Translate raw text with a trained model but will be deprecated eventually.
