Inference works fine with FA2 but when I try to train the model with the standard HF trainer, it fails with AttributeError: 'FlashAttention2' object has no attribute 'attention_dropout'

here's a minimal example to reproduce the error:

from transformers import AutoModelForCausalLM, AutoTokenizer, Trainer, TrainingArguments
from datasets import load_dataset
import torch

modelpath="models/stablelm-2-1_6b"

# model and tokenizer
model = AutoModelForCausalLM.from_pretrained(
    modelpath,    
    device_map="auto",
    torch_dtype=torch.bfloat16,
    attn_implementation="flash_attention_2",
    trust_remote_code=True,
)
tokenizer = AutoTokenizer.from_pretrained(
    modelpath, 
    use_fast=False,
    trust_remote_code=True,
)    

# dataset
dataset = load_dataset("yelp_review_full")["test"]

def tokenize_function(examples):
    return tokenizer(examples["text"], padding="max_length", truncation=True, max_length=100)

tokenized_dataset = dataset.map(
    tokenize_function, 
    remove_columns=dataset.column_names,
    batched=True)

# train
trainer = Trainer(
    model=model,
    args=TrainingArguments(output_dir="test_trainer"),
    train_dataset=tokenized_dataset,
)
trainer.train()
