torchaudio in fairseq got crashed if this lib is imported first

If import this lib first like ```py from torchfcpe import spawn_bundled_infer_model ``` then use ```py from fairseq import checkpoint_utils # fairseq version 0.12.3, torchaudio version 2.1.2 ``` The torchaudio in fairseq will got crash, here's the log ``` INFO:faiss.loader:Loading faiss with AVX2 support.
