In an attempt to access and run Matlab code via Jupyter notebook and Python, I tried installing 'matlab_kernal' (w/ typo) and 'matlab_kernel' as suggested by a blog, I didn't realize I needed MatLab, not MatLab Compiler Runtime.

I received the error: "Collecting matlab_kernal Could not find a version that satisfies the requirement matlab_kernal (from versions: ) No matching distribution found for matlab_kernal"

As a work around, I found python code on GitHub that calculated the metric I wanted, but the author said I'd need to install 'MPI' from 'mpi4py'.

However, it seems my Terminal is now stuck on my previous installation attempts of 'matlab_kernal'. It lists my previous attempts to install these packages (see all white text above red error message in the attached screen capture).

I'm running: pip 18.1 from /anaconda3/lib/python3.7/site-packages/pip (python 3.7)

I've tried:

  • pip uninstall 'package'
  • Terminal restart
  • laptop restart

Please use:

pip install matlab-kernel

Try with conda as well:

 conda install -c pchrapka matlab_kernel

I think you're making a typo with kernal.

I am on py3.7 with pip v19.3.

Output:

$ pip install matlab-kernel

  • Thanks for the catch, but even when I try to install the package with the correct spelling or totally different packages, I still get an error for 'matlab_kernal'. Check out the image I provided, it lists all the previous installation attempts. – GeoStephanieRae Nov 15 '19 at 05:23
  • @GeoStephanieRae some package with a dependency on matlab-kernel might have spelled it wrong – pissall Nov 15 '19 at 06:09
  • Yup, I’ve tried installation with the correct spelling of kernel, I’ve also tried installing other packages, but any installation attempt errors out. Regardless of what package I try to install, the result is the same; terminal lists previous instal attempts (with various packages) and errors out with: "Collecting matlab_kernal Could not find a version that satisfies the requirement matlab_kernal (from versions: ) No matching distribution found for matlab_kernal" – GeoStephanieRae Nov 15 '19 at 15:46

It's a version issue for pip and MacOS

See this thread

terminal error in MacOS from command 'pip install 'package-name': "Collecting 'package-name' Could not find a version that satisfies the requirement 'package-name' (from versions: ) No matching distribution found for 'package-name'"

Uninstall pip and reinstall pip in terminal
