Encountering error when "from sentence_transformers import SentenceTransformer"

Question

I just wrote a simple python file with the content from sentence_transformers import SentenceTransformer Then I run it. But the terminal reported the error below Traceback (most recent call last): File "/home/wmz/FlashRAG/try2.py", line 1, in from sentence_transformers import SentenceTransformer File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sentence_transformers/init.py", line 10, in from sentence_transformers.cross_encoder.CrossEncoder import CrossEncoder File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sentence_transformers/cross_encoder/init.py", line 3, in from .CrossEncoder import CrossEncoder File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sentence_transformers/cross_encoder/CrossEncoder.py", line 18, in from sentence_transformers.evaluation.SentenceEvaluator import SentenceEvaluator File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sentence_transformers/evaluation/init.py", line 3, in from .BinaryClassificationEvaluator import BinaryClassificationEvaluator File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sentence_transformers/evaluation/BinaryClassificationEvaluator.py", line 10, in from sklearn.metrics import average_precision_score File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sklearn/init.py", line 73, in from .base import clone # noqa: E402 File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sklearn/base.py", line 19, in from .utils._estimator_html_repr import _HTMLDocumentationLinkMixin, estimator_html_repr File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sklearn/utils/init.py", line 15, in from ._chunking import gen_batches, gen_even_slices File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sklearn/utils/_chunking.py", line 11, in from ._param_validation import Interval, validate_params File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sklearn/utils/_param_validation.py", line 17, in from .validation import _is_arraylike_not_scalar File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sklearn/utils/validation.py", line 21, in from ..utils._array_api import _asarray_with_order, _is_numpy_namespace, get_namespace File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sklearn/utils/_array_api.py", line 17, in from .fixes import parse_version File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/sklearn/utils/fixes.py", line 17, in import scipy.stats File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/scipy/stats/init.py", line 606, in from ._stats_py import * File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/scipy/stats/_stats_py.py", line 49, in from . import distributions File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/scipy/stats/distributions.py", line 11, in from . import _discrete_distns File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/scipy/stats/_discrete_distns.py", line 10, in from scipy.interpolate import interp1d File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/scipy/interpolate/init.py", line 167, in from ._interpolate import * File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/scipy/interpolate/_interpolate.py", line 14, in from . import _fitpack_py File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/scipy/interpolate/_fitpack_py.py", line 8, in from ._fitpack_impl import bisplrep, bisplev, dblint # noqa: F401 File "/data/anaconda3/envs/flashrag/lib/python3.9/site-packages/scipy/interpolate/_fitpack_impl.py", line 103, in 'iwrk': array([], dfitpack_int), 'u': array([], float), TypeError

I changed to another conda environment but there was no error reported. The file runded successfully. Next, I checked the version of sentence_transformers module. Both of them are 3.2.1. So, what caused it
