ImportError: DLL Load Failed

ImportError: DLL load failed while importing _ssl: The specified module could not be found.

Quick Answer

A compiled extension module cannot find its required shared library. Reinstall the package or install the missing system library.

Why This Happens

Some Python packages include compiled C extensions that depend on system libraries. If these libraries are missing or incompatible, the import fails. This is common with numpy, scipy, and packages that depend on OpenSSL.

The Problem

import numpy  # DLL load failed

The Fix

# Reinstall: pip install --force-reinstall numpy
import numpy

Step-by-Step Fix

  1. 1

    Reinstall the package

    Run pip install --force-reinstall <package>.

  2. 2

    Install system dependencies

    Check the package docs for required system libraries.

  3. 3

    Use a compatible Python version

    Some packages only have wheels for specific Python versions.
