EdgeLab installation error

Hi,
I am trying to install Edgelab on a fresh Ubuntu install, following the steps on the page below:

https://edgelab.readthedocs.io/en/latest/get_started/installation.html

There is an error on the Step 3:

Step 3. Install dependent libraries.

pip3 install -r requirements/base.txt

ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements/base.txt'

Also, the following gives the same error:

python3 tools/env_config.py

...[Errno 2] No such file or directory

It seems that my system DOES NOT have some needed files/scripts relating to Edgelab…
What is the line (command) on that page (above) where the system is supposed to download/get these, I believe, missing files?

Thanks,
any help will be appreciated,
Valter

Ok, well, this part of my problem is solved, I think…

The URL that I mention above is NOT UP TO DATE…

The real one seems to be this following one:

The wrong URL do not even mention to (git) clone the repository, and this is where the “missing files” happens…

I will try later the up to date URL…
Thanks all,
Valter
