Token indices sequence length is longer than the specified maximum sequence length for this model (10753 > 2048). Running this sequence through the model will result in indexing errors
The attention mask and the pad token id were not set. As a consequence, you may observe unexpected behavior. Please pass your input's `attention_mask` to obtain reliable results.
Setting `pad_token_id` to `eos_token_id`:106068 for open-end generation.
Input length of input_ids is 10753, but `max_length` is set to 2048. This can lead to unexpected behavior. You should consider increasing `max_new_tokens`.

错误 CUDA error: device-side assert triggered
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with `TORCH_USE_CUDA_DSA` to enable device-side assertions.
