how to fix "OSError: [WinError 193] %1 is not a valid Win32 application"

Question

我正在尝试与 pandas 相处。我正在学习 Python 使用 Thonny 作为 IDLE。我在 cmd 中使用 pip 命令安装了 pandas。不知何故我无法在我的 IDLE 中导入 pandas 方法，因此我通过设置将它添加为包。问题是：当我尝试运行以下代码时，我只在 jupyter notebook 和我的 cmd 中遇到错误，但在 thonny IDLE 中却没有。

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

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

    import pandas as pd

Answer 1

可能发生了另一件事。 VS 代码自动从预定义的 OS 位置搜索 numpy 和其他包。您可能正在使用 32 位版本的 numpy 而不是 64 位版本。要解决此问题，您可以

从所有 OS 个位置卸载 pandas。
如果问题仍然存在，请重新安装 pandas

Answer 2

我在导入 pandas 和 numpy 时收到相同的错误消息。

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\AppData\Roaming\ 中旧的 Python 文件夹解决了 issue.It 似乎 python 引用了一些旧文件导致错误。
