如何解决尝试导入numpy时出现SystemError:初始化_internal失败？

Question

问题

我编写了一个代码，将一些历史数据作为输入。假设数据集具有

timeseries

格式，我正在尝试进行回归并找到预测器。

代码

对于我的项目，我有四个文件：

my_project.py

、

utilities.py

、

plotter.py

和

constants.py

。这是两个脚本的一些小部分（相关导入）：

1. my_project.py

   ：

    from time import perf_counter
    from constants import (output_dir, DATAPATH, output_file)
    from utilities import (dataframe_in_nutshell, excel_reader, info_printer, sys, module_creator, process_discovery, data_explanatory_analysis, excel_reader, df_cleaner, feature_extractor, ml_modelling)
    from plotter import Plotter

2. utilities.py

    import os
    import sys
    import inspect
    from pathlib import Path
    from typing import (Iterable, List, Tuple, Optional)
    from itertools import zip_longest
    import matplotlib.pyplot as plt
    import statsmodels.tsa.api as smt
    import statsmodels.api as sm
    import pandas as pd
    from sklearn.metrics import mean_absolute_error
    from sklearn.preprocessing import scale
    from pycaret.regression import (setup, compare_models, predict_model, plot_model, finalize_model, load_model)
    import csv
    from constants import (np, Path, nan_value, plots_dir, HOURS_PER_WEEK, LAGS_STEP_NUM, rc_params, NA_VALUES, COLUMNS_NAMES, string_columns, LAGS_LABELS, numeric_columns, output_dir, DATAPATH, dtype_dict, train_size)
    from pprint import PrettyPrinter
    pp = PrettyPrinter()
    import seaborn as sns
    
    sns.set()

    SystemError: initialization of _internal failed without raising an exception

物流

1. 我正在 Windows 10 计算机上的 Visual Studio Code (VS Code) 中运行 my_project.py。
2. 所有包均基于使用 conda-forge 通道的 Python 3.10

研究

导入期间某处发生错误。

以下几页似乎解释了解决方法，但我不确定如何继续。 我怎样才能完成这些导入而不失败？

使用 numpy HEAD 导入时出错

更新 ufunc 循环签名解析以使用 NumPy

消除对 npy_ufunc 循环的依赖。

我今天也遇到了同样的问题。

通过将 Numpy 降级到 1.23.1 解决了这个问题

所以：

pip install numpy==1.23.1
