我正在努力与熊猫相处。我正在使用 Thonny 作为 IDLE 学习 Python。我在 cmd 中使用 pip 命令安装了 pandas。不知何故，我无法在 IDLE 中导入 pandas 方法，因此我通过设置将其添加为包。问题是：当我尝试运行以下代码时，我只在 jupyter notebook 和我的 cmd 中得到错误，但在 thonny IDLE 中没有。

import pandas as pd
df = pd.read_csv("pokemon_data.csv")
print(df)

Out(Cmd):
Traceback (most recent call last):

    import pandas as pd

导入 pandas 和 numpy 时，我收到了相同的错误消息。

File "<ipython-input-2-844cb1137ef2>", line 1, in <module>
import  pandas as pd

File "E:\Anacond\lib\site-packages\pandas\__init__.py", line 13, in <module>
__import__(dependency)

File "***C:\Users\Dell\AppData\Roaming\Python\Python37\site- 
packages\numpy\__init__.py***", line 140, in <module>
from . import _distributor_init

File "***C:\Users\Dell\AppData\Roaming\Python\Python37\site- 
packages\numpy\_distributor_init.py***", line 26, in <module>
WinDLL(os.path.abspath(filename))

File "E:\Anacond\lib\ctypes\__init__.py", line 356, in __init__
self._handle = _dlopen(self._name, mode)

OSError: [WinError 193] %1 is not a valid Win32 application

我在 E:\Anacond\ 中安装了 Anaconda，但它仍然引用C:\Users\Dell\AppData\Roaming\Python\Python37\site-packages\numpy__init__.py 我删除了 C:\Users\Dell 中的旧 Python 文件夹\AppData\Roaming\ 解决了这个问题。似乎 python 引用了一些导致错误的旧文件。

可能还发生了另一件事。numpyVS 代码自动从预定义的操作系统位置搜索和其他包。您可能使用的是 32 位版本numpy而不是 64 位版本。要解决此问题，您可以

  • pandas从所有操作系统位置卸载。
  • pandas如果问题仍然存在，请重新安装
