While trying to train seq2seq distillation model i am getting an error message that __init__() got an unexpected keyword argument 'weights_summary'.
### System Info

Transformer version : 4.21.2
pytorch-lightning             1.7.4
Used colab to test

### Information

- https://github.com/huggingface/transformers/blob/main/examples/research_projects/seq2seq-distillation/distillation.py

### Tasks

- XSUM dataset with seq2seq distillation

### Reproduction

Kindly try to train the below snippet.
!python /content/transformers/examples/research_projects/seq2seq-distillation/distillation.py \
  --teacher facebook/bart-large-xsum \
  --data_dir /content/transformers/examples/research_projects/seq2seq-distillation/xsum \
  --tokenizer_name facebook/bart-large-xsum \
  --student_decoder_layers 6 --student_encoder_layers 12 \
  --freeze_encoder --freeze_embeds \
  --learning_rate=3e-4 \
  --do_train \
  --do_predict \
  --fp16 --fp16_opt_level=O1 \
  --val_check_interval 0.1 --n_val 1000 --eval_beams 2 --length_penalty=0.5 \
  --max_target_length=60 --val_max_target_length=60 --test_max_target_length=100 \
  --model_name_or_path IGNORED \
  --alpha_hid=3. \
  --train_batch_size=16 --eval_batch_size=16 --gradient_accumulation_steps=2 \
  --sortish_sampler \
  --num_train_epochs=6 \
  --warmup_steps 500 \
  --output_dir distilbart_xsum_12_6 \
  --weights_summary None \
  "$@"

### Expected behavior

Is it something related to pt lightning version that i installed?

This example is not maintained anymore. It was written for an older version of PyTorch Lightning, so you probably need to downgrade to what was the last release at the time around its release (roughly 2 years ago).<|||||>This issue has been automatically marked as stale because it has not had recent activity.
