How to install scl on RHEL 7 workstation ?
I'm using RHEL 7 (workstation ) for the first time and having a heck of a time installing python3. I found numerous articles on how to do this : (here's one)
https://developers.redhat.com/blog/2018/08/13/install-python3-rhel/
[ partial snippet ]
$ su -
subscription-manager repos --enable rhel-7-server-optional-rpms \
--enable rhel-server-rhscl-7-rpms
yum -y install @development
yum -y install rh-python36
yum -y install rh-python36-numpy \
rh-python36-scipy \
rh-python36-python-tools \
rh-python36-python-six
Since I'm using desktop (not server ) I assume I need to change -server- to desktop.
I can't seem to find equivalent for :
--enable rhel-server-rhscl-7-rpms
This works:
subscription-manager repos --enable rhel-7-desktop-optional-rpms
Repository 'rhel-7-desktop-optional-rpms' is enabled for this system.
This doesn't: (note I'm trying server and desktop )
subscription-manager repos --enable rhel-server-rhscl-7-rpms
Error: 'rhel-server-rhscl-7-rpms' does not match a valid repository ID. Use "subscription-manager repos --list" to see valid repositories.
subscription-manager repos --enable rhel-desktop-rhscl-7-rpms
Error: 'rhel-desktop-rhscl-7-rpms' does not match a valid repository ID. Use "subscription-manager repos --list" to see valid repositories.
subscription-manager repos --list | grep scl
< returns nothing >
Could someone help me understand why rhscl is not found in subscription manager?
What is the preferred way to install python3 on RHEL 7 Desktop (workstation) ?

Hi Gregory,
Unfortunately Red Hat Software Collections are not available for the Workstation edition. Can you attach a valid Server
subscription ? If you didn't purchase a server subscription - please check out the free no-cost developer subscription. :)

Check this article. According to this Red Hat Software Collections are available for Red Hat Enterprise Workstation, but it may be necessary to make special request for it.
I was able to access a beta version for Red Hat Software Collections for my workstation subscription without any extra action to take.
How is that you get this feature for free licences and don't have it for a paid licence? It makes no sense at all!!! I'm having same roadblock installing python 3. What is the matter that you don't update the repos so we, the actual customers who are paying a licence, get that benefit from RHEL repos?
BTW... I did try to attach my RHEL Server subscription to my workstation but I also can't do that because RHEL Workstation and RHEL Server versions are not compatible, so I would need to reinstall RHEL Server and reconfigure my machine. What the hell!!!

Hi Jose,
That's not quite fair ... you forget one thing, the "free" license is NOT allowed to be used in a
production environment, it is meant to be used for development purpose exclusively. And if
you need packages from the server repositories, it would have been a good idea to take that
into consideration before deciding which RHEL edition to purchase and use. Correct, Jose ?
Cheers :)

Hi,
It seems you would like to use the workstation for Machine Learning.
Why do not you try to install Anaconda with Python 3.7 and many modules for Machine Learning:
https://www.anaconda.com/download/
I am running it at home on my CentOS 7.5 servers and at work on RHEL 7.5.
It is as simple as this:
./Anaconda3-5.3.0-Linux-x86_64.sh
You can then be very creative how to run it, even in tight environments:
$ /usr/local/anaconda3/bin/jupyter notebook --port 8899
or
$ /usr/local/anaconda3/bin/ipython notebook --ip='*'
Whilst I am at it, I strongly recommend installing a not-well-known module pandas_profile. I learned about it recently too. Very useful (you need direct Internet access or via web proxy):
# pip install pandas_profiling
or
# conda install -c anaconda pandas-profiling
