I am sorry
here is the full command I use , it is running finetune_trainer with T5
model. There is not an error, only it gives this warning. thanks


python xla_spawn.py --num_cores 8 finetune_trainer.py
--learning_rate=3e-5         --n_val 1000  --model_name_or_path t5-small
--data_dir data/wmt_en_de/ --output_dir /home/rabeeh/temp/
--overwrite_output_dir  --tpu_num_cores=8 --max_source_length=64
--max_target_length=64 --per_device_train_batch_size=32
--per_device_eval_batch_size=32 --label_smoothing=0.1 --task="translation"
--logging_steps=200 --eval_steps=500 --num_train_epochs=6 --save_steps=500
--max_source_length=128  --max_target_length=128
--val_max_target_length=128 --test_max_target_length=128

<|||||>Since you're using the T5 model I believe you can safely ignore that warning, which is useful only for the byte-level BPE tokenizers (think GPT-2, RoBERTa).

Maybe @patil-suraj or @sshleifer know why such a warning is thrown when using T5 with the `Seq2SeqTrainer`<|||||>Yeah it's happening in seq2seq dataset, you can safely ignore. Fixed in #8329 <|||||>Hi,
thank you. Is this applied to the repo? thanks

<|||||>Yes, the fix has just been merged. <|||||>Hi there, this is not fixed for me. and still I am getting it with running T5 using finetune_trainer. <|||||>Have you pulled from `master` to get the updated version?

In any case, as I've said before, this is a warning and not an error. You can safely ignore it.
