git and install .[test] issues

[rhpoon]

I followed the installation guide and found some issues that is worth mentioning,otherwise it wont work just follow the guid:

i) you need to have basic concept about "Python install from source" vs pip install and .toml file

ii) Use git clone instead of git+https.......... as suggested from the guide if you are not very adept in installing git into virtual environment. I followed the pip install git+https://github........./genna,git. It is successful, but then when get to unit tests, i have no idea where is the root of the source tree (relative to a https path) and never get it work.

The reason being in that case, the root of the source is in the ineternet git address and then i have no idea how to do this pip install -e .[test] from the "root of a surce tree located in https..." i tried a variety of ways like

$pip install -e https://..................................../.[test],

I also go to local /site-packages/gemma and do this to get it works, The installaiton works but then bunch of errors in unit tests pop out.

Basically i have no luck and get stucked, it wont work

Finally i tried out a shot tutorial on using .toml file to get familiar with "install from source" concept and used a more conventional "git clone" approach to start install in the local envrionment, i know "the root of the source tree" basically is the folder created by "git clone"

iii) Unit test - jax and jaxlib version 0.4.24, instead of 0.4.25 should be used and confirmed in the following reference. Use: pip install --force-reinstall -v "jaxlib==0.4.24", and the same for jax after the initial install to change the version. If you use "pip install jaxlib==0.4.24" to change, that may still cause you problems.

It is a challengin install from nvidia cuda, jax, and gemma install especially i am in a wsl (GPU+CPU) environment.
