ERROR: Failed building wheel for topn

Failed to build sparse-dot-topn-for-blocks topn
ERROR: Could not build wheels for sparse-dot-topn-for-blocks, which is required to install pyproject.toml-based projects`

I've tried a few different things to resolve this, including updating Visual Studio, updating pip and reinstalling Python, but to no avail. Any thoughts?

I am getting the same error while running pip install string-grouper

Has there been a resolution to this error?

[mk-bldn]

We had the same error in Ubuntu and running the below did the trick.

sudo apt-get update
sudo apt-get install --reinstall build-essential

Cant install string_grouper. This seems to be happening now that Cython 3.0 was released yesterday, and sparse_dot_topn_for_blocks no longer builds/installs
