Referring to the Readme file in [htm.core](https://github.com/htm-community/htm.core) repo. I see that the only prerequisite in Python 3.7+ version. I have Python 3.9 in my system.

However, when I try to install `htm.core` by

`python -m pip install -i https://test.pypi.org/simple/ htm.core` . I get this error message.  
`ERROR: Could not find a version that satisfies the requirement htm.core (from versions: none) ERROR: No matching distribution found for htm.core`

If anyone have stumbled upon similar issue or have any idea about sorting this issue. Please let me know.  
Thanks!

Unfortunately there is only a limited set of binaries available for the combination of Python version and OS version. So if it cannot find a match on your environment then you will need to build from sources.

Download or clone the repository  
`git clone https://github.com/htm-community/htm.core`

Build with  
`python setup.py install --user --force`

as mentioned in the README the --user and --force may not be needed depending on your Python environment.
