Installing libomp on Mac

Want to perform XgBoost for my code. Mac: macOs Mojave 10.14.6. Python version: 3.8.3. Installed Homebrew. Then performed command brew install libomp in terminal.
Problem occurred:
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "libomp".
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.
How to perform it on Mac? Is there any solution?

How to install Subversion with python bindings on Mac

I'm doing:
$ brew install subversion --with-python
Yet, homebrew reports:
Warning: subversion: this formula has no --with-python option so it will be ignored!
It goes on to install subversion, as that was only a warning, but I need the Python bindings too.
I tried --with-python in other positions, but it does not make any difference.
Here's all the output:
Warning: subversion: this formula has no --with-python option so it will be ignored!

svntools have been installed to:

The perl bindings are located in various subdirectories of:

If you wish to use the Ruby bindings you may need to add:
/usr/local/lib/ruby
to your RUBYLIB.
Bash completion has been installed to:

==> Summary
🍺 /usr/local/Cellar/subversion/1.10.2: 244 files, 30.4MB
Other info: I'm on macOS 10.13.6. Homebrew was upgraded today (no upgrades pending). There's a info page https://formulae.brew.sh/formula/subversion that suggests that --with-python is a real option, but that's not something the install command agrees with. At least on my computer. Swig is install on my mac (v3.0.12) via brew.

https://formulae.brew.sh/formula/subversion is out of date. The --with-python argument is not supported because the formula does the Python steps by default now.

Error installing Python 2 via Homebrew on MacOS Mojave

I'm having a lot of trouble with installing Python 2.7 on the MacOS 10.14 Mojave Beta.
Yes, I know that Python 2 comes pre-installed on the Mac, but I need a framework build of Python for my task.
I've tried re-installing the command line tools and then installing Python 2.7 as suggested here and here, but am still having issues - below is my output:

EDIT Please don't suggest Anaconda! For what I'm working on, I specifically need a framework built version of Python via Brew.
EDIT 2 - I tried reinstalling Sphinx, which happened with no problems. Upon doing that, I tried running install python#2 again, but had the same issue as before.

I had the same problem.
I was able to fix it by completely uninstalling and reinstalling Python after following step by step in this answer: How to fix broken python 2.7.11 after OSx updates
After the reinstallation the problem was gone

As I read you output - this is not a problem with python directly it is a problem with sphinx which builds the docs. I would go for the following steps:
brew update && brew upgrade
brew install sphinx (maybe this gives a better error message or solves the problem if sphinx is installed before)
brew reinstall python#2
If this is not working: Did you reinstalled the commandline tools after upgrading to mac os 10.14? (xcode-select --install). If not installed/updated before do it and retry.
If this all is not working could you please execute brew doctor and post the output so we can better see whats going on with your homebrew instane?
Maybe it could be a option to make an roll back to a stable version of Mac OS (10.13) ?

I'd suggest you used the Anaconda Distribution of python. Anaconda offers both python 2.7 and python 3.6 with easy to use python installers for both versions. The Anaconda page explains how to install and run python on your mac.

Trouble installing pygame. Permissions Mac OS X 10.9.5

I have been struggling to find the correct research to install pygame for about 2 days and would like to ask the community to reach a solution!
My MacBook is a backup of my old MacBook so if that is the essence of the problem, I am open to suggestions to fix it!
On the installation front
donners-mbp-2:~ Donner$ brew list
cmake isl mercurial python smpeg
freetype jpeg mpfr readline sphinx-doc
gcc libmpc numpy sdl sqlite
gdbm libpng openssl sdl_image webp
git libtiff pkg-config sdl_mixer
gmp makedepend portmidi sdl_ttf
upon researching I should use this code in terminal to install however I receive an error message following:
donners-mbp-2:~ Donner$ /usr/local/share/python/pip install hg+http://bitbucket.org/pygame/pygame
donners-mbp-2:~ Donner$ /usr/local/share/python/pip: No such file or directory
Taking a look into my "Home" Directory - AKA Macintosh HD - I have the Library directory within not in my user folder (AKA directly on the main HD).
Should I move that to my user folder then try again?
When running the pygame install here is what is on my command line.

Thank you for any help/suggestions!

(Posted on behalf of the OP).
This is solved.
I followed this to show hidden files in my $PATH and establish a new $PATH. https://coolestguidesontheplanet.com/add-shell-path-osx/
Then un-installed and reinstalled pygame, following the comments here: https://www.reddit.com/r/Python/comments/2jfj1w/how_to_install_pygame_on_osx_1095/. Specifically the comment by redditor PigBoyOhBoy (with some adjustments for Python 2.7 rather than Python 3).

brew install opencv3 apparently successful, but missing cv2.so and cv2.py

I'm trying to setup a working environment on my mac:
brew install opencv3 --c++11 --with-contrib --with-gphoto2 --with-python3
==> Installing opencv3 from homebrew/homebrew-science
...
==> cmake .. -DCMAKE_C_FLAGS_RELEASE= -DCMAKE_CXX_FLAGS_RELEASE= -DCMAKE_INSTALL
==> make
==> make install
==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.
opencv3 and opencv install many of the same files.
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
LDFLAGS: -L/usr/local/opt/opencv3/lib
CPPFLAGS: -I/usr/local/opt/opencv3/include
==> Summary
🍺 /usr/local/Cellar/opencv3/3.0.0: 351 files, 110M, built in 5.4 minutes
So homebrew seems to think the install went well, but
locate cv2.so finds nothing...
locate *cv*.so
finds only
/usr/local/Cellar/opencv3/3.0.0/lib/python3.5/site-packages/cv2.cpython-35m-darwin.so
and
/usr/local/lib/python3.5/site-packages/cv2.cpython-35m-darwin.so
cv2.py or cv.py does not exist as well...
Any ideas?

ive seen this error before using raspian, its also seen in ubuntu, renaming cv2.cpython-35m-darwin.so to cv2.so may help fix the issue.
ive heard it just a standard naming error.
