### Information

- [ ] The official example scripts
- [X] My own modified scripts

### Tasks

- [ ] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [X] My own task or dataset (give details below)

### Reproduction

I'm constructing a dataset (.parquet format) that is similar to json format, but has other fields to construct graph for examples in the dataset. When I'm training the model in DDP mode (distributed), I'm getting `RuntimeError: Socket Timeout`. Here is the full stack:

Not sure if it's related to dataset (.parquet format). Could you please post the code snippet you used to launch the script ?

I succeeded in pre-training without DDP. Running tokenizer was finished well and I could use this cache data with DDP after tokenizing.
I don't know the cause yet, but this problem seems to be related to DDP.

My English is not that great. Nevertheless I want to solve this problem.<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.

Mine was above >100GB, most of which related to the graph fields that I had put in each example (in the parquet file). I could manage to get this passed by running on a single GPU, and then using cached file for fast load in multi-GPU setting. <|||||>This issue has been automatically marked as stale because it has not had recent activity.

## My system info:
- `transformers` version: 4.24.0
- Platform: Linux-4.15.0-166-generic
- Python version: 3.8.10
- PyTorch version (GPU?):  1.10.2+cu113 (True)
- Tensorflow version (GPU?): not installed (NA)
- Flax version (CPU?/GPU?/TPU?): not installed (NA)
- Jax version: not installed
- JaxLib version: not installed
- Using GPU in script (Number)?: Yes (7-8 GPUs).
- Using distributed or parallel set-up in script?: Yes (run_clm.py script)
- Number of nodes in distributed: 1

## My run information
- Modified scripts: My own modified script of run_clm.py, released in version 4.24.0.
- Dataset: [openwebtext](https://huggingface.co/datasets/openwebtext) (from the hub)

## Notes
- When using smaller dataset (e.g. wikitext-2, wikitext-103) I'm not having the issue.
- As mentioned above, the error appears after ~30 minutes. In my case 31:05 minutes.

## Reproduction
I'm running the following:
> torchrun \
    --standalone \
    --nnodes=1 \
    --nproc_per_node=${NUM_GPU} \
    ./code/gpt2/Model-Compression-Research-Package/examples/transformers/language-modeling/run_clm.py \
    --model_name_or_path ${MODEL} \
    --dataset_name ${DS_NAME} \
    --save_steps ${SAVE_STEPS} \
    --logging_steps 1000 \
    --eval_steps 2000 \
    --do_train \
    --do_eval \
    --seed ${RANDOM} \
    --max_steps ${MAX_TRAIN_STEPS} \
    --learning_rate ${LR} \
    --per_device_train_batch_size ${TRAIN_BATCH} \
    --gradient_accumulation_steps ${ACC_STEPS} \
    --per_device_eval_batch_size ${EVAL_BATCH} \
    --evaluation_strategy steps \
    --logging_dir ${OUTPUT_DIR} \
    --output_dir ${OUTPUT_DIR} \
    --overwrite_output_dir \
    --load_best_model_at_end \
    --max_train_samples 200 \
    --max_eval_samples 200 \

And I'm having the following error output:

Thanks a lot in advance for looking into it<|||||>You are not using the [`ddp_timeout`](https://huggingface.co/docs/transformers/main_classes/trainer#transformers.TrainingArguments.ddp_timeout) training argument to put a higher value than 30 minutes, so if you have a big dataset to preprocess, you get this error. Use a bigger value to solve this error or preprocess your dataset in a non-distributed fashion.<|||||>@sgugger what if I am launching my script with a "torch.distributed.launch" utility?
Then, even if I update the ddp_timeout it does not get reflected, and the processes halt in 30 minutes (the default time).<|||||>met same problem<|||||>If you use `torch.distributed.launch` with a `ddp_timeout` that is not listened to, it sounds like a bug in PyTorch ;-)
