BUG: TypeError: 'NoneType' object is not callable

See original GitHub issue

Describe the issue:

Use sample.zip to run the example

I need to know whether this is a numpy issue or a cython issue or pycharm’s. The error only happens in pycharm debugger under ambiguous circumstances, and it is a known issue. There are mentions that it’s a cython issue despite the failure occurring in numpy/core/getlimits.py Line 649. I need to know where the problem originates and if it’s a numpy issue, is there some merged fix?

Update: The error is gone after building cython with the fix, numpy, pandas, and scikit-learn

Reproduce the code example:

import pandas as pd
from sklearn.feature_extraction.text import CountVectorizer

df = pd.read_parquet('sample.parquet')
corpus = df[df['cell_type'] == 'markdown']['source']
vec = CountVectorizer(ngram_range=(1, 1))
vec.fit(corpus)

Error message:
