ValueError：使用autofaiss时找不到子字符串

Question

Traceback (most recent call last):
  File "c:\Users\kaili\Documents\New folder (2)\x.py", line 5, in <module>
    index, index_infos = build_index(embeddings, save_on_disk=False)

    prefix = path[: path.index(path_in_fs)]
ValueError: substring not found

试图使用Autofaiss创建FAISS索引，但无论我总是最终找不到sudstring。这是我在一个全新的虚拟环境中尝试的。代码在这里（取自其github的一个示例之一），

from autofaiss import build_index
import numpy as np

embeddings = np.float32(np.random.rand(100, 512))
index, index_infos = build_index(embeddings, save_on_disk=False)
_, I = index.search(embeddings, 1)
print(I)

我不知道错误来自哪里。如果有人能弄清楚什么是搞砸了，那将要感谢。
