如何修復“在Windows上將'Ipython'和'Jupyter Notebook'導入熊貓失敗”

Question

我的系統上安裝了熊貓 ，但無法正常工作並發送錯誤ModuleNotFoundError：ipython中沒有名為“ pandas”的模塊。

當我嘗試在ipython中導入熊貓時收到錯誤消息：

    In [1]: import pandas
---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-38d4b0363d82> in <module>
----> 1 import pandas

ModuleNotFoundError: No module named 'pandas'

當我嘗試在jupyter筆記本中導入熊貓時收到錯誤消息：

--------------------------------------------------------------------------

    358             self._handle = handle

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

我嘗試卸載並重新安裝熊貓，但是沒有運氣

Answer 1

在您的iPython Notebook中，您可以嘗試運行以下命令嗎？

!pip install pandas

然后重新啟動您的iPython Notebook內核？

您很可能已將熊貓安裝到其他虛擬環境中。

Answer 2

您是否嘗試使用其他解釋器運行代碼（例如Visual Studio Code）或從終端運行，有時解釋器的模塊目錄可能與使用pip的模塊安裝目錄不同。
