How to fix "No Lapack/Blas Resources Found" error when installing SciPy on Windows

Are you a 🐍Python enthusiast trying to set up your coding environment on a Windows machine? Have you encountered the pesky "No Lapack/Blas Resources Found" error while installing the powerful 🧪SciPy library? Fear not! We're here to guide you through this obstacle and get you back on track to coding 🚀.

Understanding the problem

The error message you encountered:

numpy.distutils.system_info.NotFoundError: no lapack/blas resources found

indicates a missing dependency required by SciPy - specifically, the Lapack/Blas resources. These resources are crucial for performing efficient numerical computations.

Common causes of the error

Here are a few common causes for this error:

1. Incomplete installation or missing dependencies: It's possible that your installation of Python or the supporting packages (such as NumPy) didn't complete successfully, resulting in missing resources.

2. Incorrect compiler version: Depending on your Python version and the compiler you're using, compatibility issues may arise. This is particularly relevant if you're using Python 3.4 and Visual Studio C++ 2010, as mentioned in your context.

Easy solutions

Let's explore a couple of easy solutions that should help you overcome this error:

Solution 1: Using a pre-compiled binary

Instead of relying on pip install, you can try using a pre-compiled binary for SciPy. This binary already includes the necessary Lapack/Blas resources, saving you the trouble of compiling them yourself.

1. Visit the Unofficial Windows Binaries for Python Extension Packages website.

2. Search for the appropriate version of SciPy that matches your Python installation.

3. Download the corresponding .whl file (for example, scipy‑x.x.x‑cp34.cp35.cp36.cp37‑win_amd64.whl).

4. Open your command prompt and navigate to the directory where the downloaded file is located.

5. Install SciPy using the following command (replace x.x.x with the appropriate version):

   pip install scipy-x.x.x-cp34.cp35.cp36.cp37-win_amd64.whl

Solution 2: Compiling from source

If the pre-compiled binary doesn't work for you, you can try compiling SciPy from source. Here's a step-by-step guide:

1. Install the necessary build dependencies:

   • Microsoft Visual C++ Compiler for Python 2.7 (for Python 2.7)

   • Microsoft Build Tools for Visual Studio (for Python 3.x)

2. Download the SciPy source code from the official SciPy GitHub repository.

3. Extract the downloaded source code to a directory of your choice.

4. Open the command prompt and navigate to the extracted directory.

5. Execute the following command to start the compilation process:

   python setup.py install

   Note: Make sure you have your Python installation directory in your system's PATH environment variable.

6. Wait for the compilation and installation to complete.
