text: Title: Unable to use Seq2SeqTrainingArguments and Seq2SeqTrainer
  Body: ### System Info
  
  I am using the following versions:
  
  - tensorflow 2.18.0
  - tensorboard 2.18.0
  - transformers 4.49.0 
  - keras 3.8.0
  - Python 3.10.0
  
  ### Who can help?
  
  _No response_
  
  ### Information
  
  - [x] The official example scripts
  - [x] My own modified scripts
  
  ### Tasks
  
  - [x] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
  - [ ] My own task or dataset (give details below)
  
  ### Reproduction
  
  I want to use `Seq2SeqTrainingArguments` and `Seq2SeqTrainer`. The code was working using old version of `transformers 4.28.1`.
  
  Here is the minimal executable example:
  ```
  import transformers
  from transformers import Seq2SeqTrainingArguments, Seq2SeqTrainer
  
  training_args = Seq2SeqTrainingArguments()
  ```
  The main error is: 
  ```
  RuntimeError: Failed to import transformers.trainer_seq2seq because of the following error (look up to see its traceback):
  Failed to import transformers.integrations.integration_utils because of the following error (look up to see its traceback):
  Failed to import transformers.modeling_tf_utils because of the following error (look up to see its traceback):
  module 'tensorflow._api.v2.compat.v2.__internal__' has no attribute 'register_load_context_function'
  ```
  
  I am using the following versions:
  
  - tensorflow 2.18.0
  - tensorboard 2.18.0
  - transformers 4.49.0 
  - keras 3.8.0
  - Python 3.10.0
  
  But the official example uses similar codes: https://github.com/huggingface/transformers/blob/main/examples/pytorch/translation/run_translation.py#L595
  
  **My question is**: apart from downgrading the `transformers`, how do I fix this issue? Thanks.

  Steps to reproduce:
  
  1. Install `transformers 4.49.0` and other libraries listed above (with their dependencies installed); no conflict is reported.
  2. Write the minimal example above in the Jupyter Notebook / a Python script (results are the same).
  3. The above errors occurred.
  
  ### Expected behavior
  
  In `transformers 4.28.1`, the `Seq2SeqTrainingArguments` won't cause errors. The translation example in this GitHub is using the same code as well. No error should be expected.
