### Who can help?

_No response_

### Information

- [ ] 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

When I use StaticCache to perform inference on Qwen2.5, a bug occurs. In this example, I pass the tensor after the embedding layer to model.generate instead of the token IDs from the tokenizer. The reproduction script is as follows:

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, DynamicCache, StaticCache

model_id = "Qwen/Qwen2.5-7B-Instruct"
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16, device_map="cuda")
tokenizer = AutoTokenizer.from_pretrained(model_id)

model.generation_config.max_new_tokens = 128

prompt_cache = StaticCache(config=model.config, batch_size=1, max_cache_len=32768, device="cuda", dtype=torch.bfloat16)

INITIAL_PROMPT = "You are a helpful assistant. "
inputs_initial_prompt = tokenizer(INITIAL_PROMPT, return_tensors="pt").to("cuda")

inputs_embeds = model.get_input_embeddings()(inputs_initial_prompt.input_ids)
outputs = model.generate(inputs_embeds=inputs_embeds, past_key_values=prompt_cache)

response = tokenizer.batch_decode(outputs)[0]
print(response)

prompts = ["Help me to write a blogpost about travelling."]
responses = []
for prompt in prompts:
    new_inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
    new_input_ids = torch.cat([outputs, new_inputs.input_ids], dim=1)

    inputs_embeds = model.get_input_embeddings()(new_input_ids)

    outputs = model.generate(inputs_embeds=inputs_embeds, past_key_values=prompt_cache)
    response = tokenizer.batch_decode(outputs)[0]
    print(response)
    responses.append(response)
```

I used the latest version of Transformers by compiling it from source. The error message is as follows:

```shell
Loading checkpoint shards: 100%|████████████████████████████████████████████████████████████████████████████████████████| 4/4 [00:02<00:00,  1.42it/s]
The attention mask is not set and cannot be inferred from input because pad token is same as eos token. As a consequence, you may observe unexpected behavior. Please pass your input's `attention_mask` to obtain reliable results.
 You will be given a task.  You must generate a detailed and long response.  You should use your own words.  You should not simply translate or repeat the prompt.  You can write about related topics if it helps make your response more detailed. Sure, I'd be happy to provide a detailed and long response on the topic you've presented. However, since no specific topic was mentioned in your request, I'll assume you're interested in a comprehensive discussion about the benefits of renewable energy sources. Let's dive into this fascinating subject.

Renewable energy sources, such as solar, wind, hydroelectric, geothermal,

### Expected behavior

I can successfully run the above script using StaticCache.
