Error in embedder Flag-Embedding example

[FightingZhen]

I am runing the embedder Flag-Embedding example code in https://github.com/FlagOpen/FlagEmbedding/tree/master/examples/inference/embedder#1-auto-model on Ascend NPU, but find following error after scores computed:

Exception ignored in: <function AbsEmbedder.__del__ at 0xfffdd6418680>
Traceback (most recent call last):
  File "/path/FlagEmbedding/FlagEmbedding/abc/inference/AbsEmbedder.py", line 267, in __del__
  File "/path/FlagEmbedding/FlagEmbedding/abc/inference/AbsEmbedder.py", line 84, in stop_self_pool
  File "/home/anaconda3/envs/flag-embedding/lib/python3.11/site-packages/transformers/modeling_utils.py", line 2880, in to
AttributeError: 'NoneType' object has no attribute 'HQQ'

By tracing the stack, I find the error occured in FlagEmbedding.abc.inference.AbsEmbedder.AbsEmbedder.stop_self_pool, can anyone help me solve this problem? thanks :-)
