导入 pandas 时出错“ImportError：无法确定 numexpr 的版本”

Question

我在导入

pandas

包时遇到问题。我使用以下命令导入它：

import pandas as pd

但是，我收到以下错误消息：

Traceback (most recent call last):
 
  Cell In[54], line 1
    import pandas as pd

ImportError: Can't determine version for numexpr

我正在使用以下版本的Python：

Python 3.10.10 | packaged by Anaconda, Inc. | (main, Mar 21 2023, 18:39:17) [MSC v.1916 64 bit (AMD64)]

有什么办法可以解决这个问题吗？

一些重要信息可能是这台计算机可以通过 VPN 远程访问我正在使用的服务器。所以我只能在登录 VPN 时才能访问该程序。

Answer 1

如果你使用的是ubuntu linux，你可以尝试

sudo apt-get install python-numexpr

。请参考这个答案 - https://askubuntu.com/questions/446644/why-do-i-get-importerror-when-trying-to-import-pandas-python-module

安装numexpr和bottleneck后，您可以尝试

pip install --force-reinstall pandas

或

pip install --upgrade --force-reinstall pandas

以确保pandas安装正确。

Answer 2

系统和Python版本：

NAME:"Kali GNU/Linux" 
VERSION_ID:"2023.4"
VERSION:"2023.4"
PYTHON_VERSION:"3.11.6"

代码：

import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
datasets = [11, 17, 16, 15, 14, 13, 12, 256, 255, 250]
dataset=sorted(datasets)
print(f"Sorted Dataset: {dataset}")
q1,q3=np.percentile(dataset,[25,75])
print(f"Q1: {q1}, Q3: {q3}")
iqr=q3-q1
print(f"IQR: {iqr}")
lower_fence=q1-(1.5*iqr)
upper_fence=q3+(1.5*iqr)
print(f"Lower Fence: {lower_fence}, Upper Fence: {upper_fence}")
sns.boxplot(datasets)
plt.show()

错误：

ImportError: Can't determine version for numexpr

我的解决方案：

pip install numexpr
pip install bottleneck
