Installing matbench

I’m having troubles installing matbench. Here is the pip install failure in colab…

In Anaconda, I get a similar error. Something to do with Cython & scikit-learn? I copy/pasted my PC/Anaconda-cmd output into the colab notebook above.

I have also been running into and dealing with this error. Which version of python are you using?

I’ve tested this by creating various blank conda environments with various python versions, 3.6 - 3.11, then installing matbench with pip. This failed with the same error message you had for python versions 3.10 and 3.11. The matbench installation was successful for python versions 3.7, 3.8, and 3.9. 3.6 failed for a different reason related to dependencies.

Example commands to create empty conda environment and matbench pip install

conda create --name matbench_3.7 python=3.7 --no-default-packages
pip install matbench
