pip install issues

[onaclov2000]

I'm fairly unfamiliar with how pip works, however I guess the newer versions only allow installing of certain release number formats. so the default "pip install <>" isn't working.
This SO question/answer talks about the format/convention that is necessary for the newer pip installs.

Pre-release Versions

Starting with v1.4, pip will only install stable versions as specified by PEP426 by default. If a version cannot be parsed as a compliant PEP426 version then it is assumed to be a pre-release.

If a Requirement specifier includes a pre-release or development version (e.g. >=0.0.dev0) then pip will allow pre-release and development versions for that requirement. This does not include the != flag.

The pip install command also supports a --pre flag that will enable installing pre-releases and development releases.

So I finally tried

pip install --pre pymdptoolbox 

and it worked

I'm not sure if an update to the "how to install" is in order, or the pip name format needs updating
