在 Windows 10 Python 3.7.9（IDLE）上，我成功安装了“pip install numexpr”，但在“import numexpr as ne”时出现错误：
Traceback（最近一次调用）： 文件“<pyshell#21>”，第 267 行，位于 将 numexpr 导入为 ne 文件“C:\Python379\lib\site-packages\numexpr_ init _.py”，第 28 行，位于 从 numexpr.interpreter 导入 MAX_THREADS、use_vml、__ BLOCK_SIZE1__ ImportError: DLL 加载失败: 找不到此模块。
也许我需要以其他方式安装 Numexpr
Looks like you are encountering a common issue related to the Microsoft Visual C++ Redistributable package, which is essential for many Python libraries like Numexpr to function properly. Here's a breakdown of the problem and how to fix it:
Understanding the Error
The error message "ImportError: DLL load failed: The specified module could not be found" often arises when Python cannot locate the necessary DLL (Dynamic Link Library) files that Numexpr relies on. These DLLs are typically provided by the Microsoft Visual C++ Redistributable.
Solution
- Identify Your Python Version (32-bit or 64-bit):
-
Open your Python interpreter (IDLE) and run the following code:
python import platform print(platform.architecture()) -
This will tell you if you have a 32-bit (e.g., '32bit') or 64-bit (e.g., '64bit') installation of Python.
-
Download and Install the Correct Visual C++ Redistributable:
- Important: Match the version (32-bit or 64-bit) with your Python installation.
- Visit the official Microsoft website: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
-
Download and install the appropriate Visual C++ Redistributable for Visual Studio. For example, if you have Python 3.7, you'll need the redistributable for Visual Studio 2015, 2017, 2019, and 2022.
-
Restart Your System:
-
After installing the redistributable, it's essential to restart your computer for the changes to take effect fully.
-
Test Numexpr:
-
Open a new Python interpreter (IDLE) session and try importing Numexpr again:
python import numexpr as ne
Additional Tips
-
If the issue persists, consider reinstalling Numexpr using pip:
bash pip uninstall numexpr pip install numexpr -
Ensure that you're not working in a virtual environment that might have conflicting library installations.
Let me know if you have any questions or if the error persists. I'll be happy to help further!
