The "Module Compiled Against API Version 0xC but this Version of NumPy is 0xB" error occurs when there's a mismatch between the installed version of NumPy and the required version for a specific module. In this guide, you'll learn how to resolve this error, step-by-step.

Identifying the Problem
Before diving into the solutions, it's important to understand the error message. The error indicates that a specific module (such as pandas, TensorFlow, etc.) was compiled against a newer version of NumPy's API (0xC) than the one installed on your system (0xB).
This mismatch can cause various issues, including unexpected behavior, crashes, or even data corruption. Therefore, it's crucial to resolve this error as soon as possible.
The first and most straightforward solution is to update the installed version of NumPy to match the required version for the module. Follow these steps to update NumPy:
- Open your terminal or command prompt.
- Ensure that you have the latest version of pip, the Python package manager, by running the following command:
pip install --upgrade pip
- Update NumPy to the latest version by running:
pip install --upgrade numpy
- Verify that the updated version of NumPy has resolved the error by running your script or importing the affected module.
If the error persists, you might need to downgrade the module to a version that's compatible with the installed version of NumPy.
Downgrading the Module
In some cases, you might not be able to upgrade NumPy to the latest version due to other dependencies or constraints. In such scenarios, you can downgrade the module that's causing the error to a version that's compatible with the installed version of NumPy.
To downgrade the module, follow these steps:
- Identify the module causing the error (e.g., pandas, TensorFlow, etc.).
- Uninstall the current version of the module by running:
pip uninstall <module_name>
- Install an older version of the module that's compatible with the installed version of NumPy by running:
pip install <module_name>==<compatible_version>
You might need to consult the module's documentation or release notes to find a compatible version.
- Verify that the error has been resolved by running your script or importing the affected module.
1. What is NumPy?
NumPy, which stands for Numerical Python, is a popular library for numerical computing in Python. It provides efficient, easy-to-use data structures like arrays and matrices, as well as a large collection of mathematical functions to operate on these data structures. Learn more about NumPy.
2. Why do I get this error with specific modules?
Some Python modules, such as pandas and TensorFlow, rely on NumPy for certain operations. If the module was compiled against a different version of NumPy's API than the one installed on your system, you might encounter this error.
3. How do I check the installed version of NumPy?
You can check the installed version of NumPy by running the following command in your terminal or command prompt:
pip show numpy
Alternatively, you can also check the version within a Python script or interactive shell:
import numpy as np
4. How do I find a compatible version for the module causing the error?
To find a compatible version of the module, consult the module's documentation or release notes. You can also check the module's GitHub repository for information on compatibility with different versions of NumPy.
5. Can I have multiple versions of NumPy installed?
No, you can only have one version of NumPy installed in a given Python environment. However, you can create separate virtual environments for different projects, each with its own version of NumPy and other dependencies. Learn how to create virtual environments.
