如何解決“ImportError: DLL load failed while importing _arpack: The specified procedure could not be found.”？

Question

在為我的 Windows 10 安裝 Anaconda 3 的新副本並運行我的代碼后，我收到此錯誤消息，我不確定為什么“scipy”模塊沒有正確導入。 我需要幫助來解決這個問題。

$ D:/Users/用戶名/Anaconda3/python.exe d:/Users/用戶名/Desktop/sol-tl/sol_357.py

考慮到Anaconda (3.9.12) 的新版本存在“Scipy”包的問題，​​我從Conda中刪除了該包並使用pip重新安裝了它。 現在，代碼運行愉快。
