Cannot pickle error in Dataset.from_generator()

### Describe the bug

I'm trying to use Dataset.from_generator() to generate a large dataset. 

### Steps to reproduce the bug

Code to reproduce:
```
from transformers import T5Tokenizer, T5ForConditionalGeneration, GenerationConfig
import torch
from tqdm import tqdm
from datasets import load_dataset

tokenizer = T5Tokenizer.from_pretrained("google/flan-t5-small")
model = T5ForConditionalGeneration.from_pretrained("google/flan-t5-small", device_map="auto")
model = torch.compile(model)

def generate_data(data_loader):
    model.eval()
    for batch in tqdm(data_loader):
        input_ids = tokenizer(batch['instruction'], return_tensors='pt', padding=True, truncation=True).input_ids.to("cuda:0")
        with torch.no_grad():
            outputs = model.generate(input_ids, generation_config=generation_config)
        decoder_hidden_states = outputs.decoder_hidden_states
        for i, h in zip(batch['instruction'], decoder_hidden_states):
            yield {"instruction": i, "decoder_hidden_states": h}

generation_config = GenerationConfig(
    temperature=1,
    max_new_tokens=1024,
    do_sample=False,
    num_return_sequences=1,
    return_dict_in_generate=True,
    output_scores=True,
    output_hidden_states=True,
)
from datasets import Dataset, load_dataset
from torch.utils.data import DataLoader
dataset = load_dataset("HuggingFaceH4/databricks_dolly_15k")
train_loader = DataLoader(dataset['train'], batch_size=2, shuffle=True)
dataset = Dataset.from_generator(generator=generate_data, gen_kwargs={"data_loader": train_loader})
dataset.save_to_disk("data/flant5_small_generation")
    
```


### Expected behavior

The dataset should be generated and saved.
But the following error occurred:
```

Hi! It should work if you put `model = torch.compile(model)` inside the `generate_data` function. If a referenced object is outside, it needs to be pickable, and that's not the case for the compiled models (or functions).

Hi! Thank you for your reply! Everything works perfectly with your suggestion!

Closing the issue.
