Who can help?

Reproduction (minimal, reproducible, runnable)

I am trying to fine-tune Llama-3-8B on a single trn1.2xlarge instance. I am following the tutorial here: https://huggingface.co/docs/optimum-neuron/en/training_tutorials/sft_lora_finetune_llm but changing PROCESSES_PER_NODE and TP_DEGREE variables. My compilation script looks like this:

#!/bin/bash
set -ex

export NEURON_FUSE_SOFTMAX=1
export NEURON_RT_ASYNC_EXEC_MAX_INFLIGHT_REQUESTS=3
export MALLOC_ARENA_MAX=64
export NEURON_CC_FLAGS="--model-type=transformer --distribution-strategy=llm-training --enable-saturate-infinity --cache_dir=/home/ec2-user/cache_dir_neuron/"

PROCESSES_PER_NODE=2

NUM_EPOCHS=1
TP_DEGREE=2
PP_DEGREE=1
BS=2
GRADIENT_ACCUMULATION_STEPS=8
LOGGING_STEPS=1
MODEL_NAME="meta-llama/Meta-Llama-3-8B"
OUTPUT_DIR=output-$SLURM_JOB_ID

MAX_STEPS=25

  --logging_steps $LOGGING_STEPS \
  --save_total_limit 1 \
  --output_dir $OUTPUT_DIR \
  --lr_scheduler_type "constant" \
  --overwrite_output_dir

however, during compilation of some graphs I get this error:

You may also be able to obtain more information using the 'XLA_IR_DEBUG' and 'XLA_HLO_DEBUG' environment variables.

I can compile and complete training without error if I set the batch_size to 1, however I would like to be able to increase the batch size to speed up training.
I also get these warnings which may be relevant:

torch.distributed process group is initialized, but parallel_mode != ParallelMode.DISTRIBUTED. In order to use Torch DDP, launch your script with `python -m torch.distributed.launch
[2024-10-05 19:58:00.706: W neuronx_distributed/parallel_layers/parallel_state.py:439] [rank_0_pp-1_tp-1_dp-1] Failed to initialize NKI parallel state with exception intra_layer_model parallel group is not initialized.Proceeding without distributed NKI support.

Expected behavior

I expect the model to compile and training script to function properly without error.
