How to download matplotlib for python 3.7 in windows 8?

How do you download matplotlib to windows so I can use it with python?
Every other question related to this that I've found on StackOverflow has led to the same problem which is that it keeps giving me the error:
python setup.py egg_info failed with error code 1 in C:\Users\Myname\AppData\Local\Temp\pip-install-9gc765gs\matplotlib\
Things I have tried (from the command prompt):
pip install matplotlib
pip install matplotlib-1.5.0-cp35-none-win_amd64.whl (which is the file I downloaded from SourceForge and is now stored in my computer)
pip install "matplotlib-1.5.0-cp35-none-win_amd64.whl"
python -mpip install -U matplotlib
I even tried tried:
pip install --upgrade setuptools
python -mpip install -U pip
prior to using the other commands to make sure everything was up to date.
Any help would be very appreciated.

Matplotlib has not been officially released for Python 3.7 yet.
As of this writing, a 3.7 version for Mac and Linux has been uploaded to PyPI earlier today, which means the Windows versions are probably coming very soon. pip will probably work after that.
Similarly, no 3.7 compatible versions have been put onto conda-forge or integrated into the main conda repo yet. I'm sure those will be coming in the next couple of weeks.
Until then, maybe installing from source will work?

Downgrading python package installed locally

In the server that work in (as do many other people) the "global" python has a certain version of a package, say 1.0.0.
I recently used pip to upgrade that to 1.0.2 locally for my user with the pip install --user package==1.0.2, which worked. However, now I want to uninstall my locally installed version and remain with the global one.
I've tried pip uninstall --user package==1.0.2, pip uninstall --user package, and a few other options but nothing seems to work. I always get this error:
Usage:
pip <command> [options]
no such option: --user
I also tried pip install --user package=1.0.0 but now I have both versions installed locally and python uses the most recent.
How can I do what I want?

Apparently this cannot be done with pip directly. I ended up solving it just by removing the package from ~/.local/lib/python3.5/site-packages/. A bit more manual than I was hoping I'd have to do.

The --user option for pip seems to have been removed but is still an option with setuptools.
So if you want to use the --user function what you can do is use pip download which will download the .whl file. You then need to extract the file using wheel unpack. I then ran python setup.py install --user (worked for numpy) and it installed the package to my home directory under .local.
I followed the documentation here.

Install opencv-python under python3 ubuntu 14.04

I want to use opencv under python 3 in Ubunto 14.04. I plan to use the PyCharm IDE to develop my program.
Inside PyCharm I choose, I set:
File/Settings/Project:HelloWorld/Project Interpreter/3.4.3(/usr/bin/python3.4)
Python 3.4.3 is the default version of python in Ubunto 14.04.
Then I try to add opencv-python package:
File/Settings/Project:HelloWorld/Project Interpreter/+ (where you add the package)
and the system gives me this error:
Executed command:
pip install opencv-python
Try to run this command from the system terminal. Make sure that you
use the correct version of 'pip' installed for your Python interpreter located at '/usr/bin/python3.4'.
DEPRECATION: --no-install, --no-download, --build, and --no-clean are deprecated. See https://github.com/pypa/pip/issues/906.
Downloading/unpacking opencv-python
Could not find any downloads that satisfy the requirement opencv-python
Cleaning up...
No distributions at all found for opencv-python
Storing debug log for failure in /root/.pip/pip.log
the error is the same when I run the command from terminal. I believe the problem is related to installing opencv under python3 but I am not sure I know if I can fix it. Please let me know your opinion.
Thanks

The fix is to update your pip and try again. This worked for me.
So, first:
pip install --upgrade pip
after that:
pip install opencv-python

First, you should not use install opencv-python, this is not the official opencv package.
Please, see:
**SOLVED** How to include libgtk2.0-dev and pkg-config in cmake when installing openCV on Ubuntu 16
If you want to install opencv, you can follow this website, that worked for me. You might need to apapt some parts (mainly version numbers, and paths during the cmake process).

I also faced similar issue in the windows and pip upgrade worked for me,
pip install --upgrade pip
and install using below command,
pip install opencv-python

As far as I can see from querying pip (using pip search opencv) there is no package called opencv-python I think the one you're looking for is pyopencv.
this issue appears to be almost identical

Unable to install pip on suse

Pretty new to linux/suse and python so excuse me if I cause some simple questions.
I've search through stackoverflow and haven't gotten a result for my question.
I'm running on Windows with a Virtual machine using SUSE. I'm trying to install py.test, but to install it, it needs either pip or easy_install. I've heard pip is preferred over easy_install, so I tried installing that with get-pip.py.
I run it with
python get-pip.py
and it tells me it has been installed, this is what it ouputs
Collecting pip
Using cached pip-6.1.1-py2.py3-none-any.whl
Collecting setuptools
Using cached setuptools-15.1-py2.py3-none-any.whl
Installing collected packages: pip, setuptools
Successfully installed pip-6.1.1 setuptools-15.1
I tried running
pip install -U pytest
however the command pip has not been found. I also looked into python-pip package via openSUSE, though I'm not sure how to open a .ymp file through a VM.
Would I have to add a path for it to work? Pointers would be appreciated.

It looks like pip was unstalled by a regular user, so it was installed under the user's homedir, thus needs to be explicitly added to the path.
On openSUSE I'd suggest installing it using YaST (as root) and it'll end up in /usr/bin/pip, shareable by all users. Here's how it looks like on openSUSE 13.2:
$> which pip
/usr/bin/pip
$> rpm -qf /usr/bin/pip
python3-pip-1.5.6-2.1.3.noarch
Just search for pip in the software management tool.
Also many additional python packages/modules come prepackaged as openSUSE RPMs, better check the software management tool 1st.

Installing pip for an offline machine on Python 2.7, CentOS 6.3

I'm trying to install lxml for Centos6.3, due to this issue. It looks like I've got a conflicting version of pip. The standing solution seems to re-install pip for the correct version of python.
My main issue is that all the methods I've found for installing pip require an internet connection. Is it possible to download pip install files, and then run pip install -U pip and point it at the right files?
The PyPI page for pip only has pip6.11 as a .whl. I've tried running pip install -U pip-6.1.1-py2.py3-none-any.whl and it's not worked.
I'm stumped. How do I install it?

You could try to download pip and setuptools manually from: https://pypi.org/project/pip/#files and https://pypi.org/project/setuptools/#files
get the python pip script from: https://bootstrap.pypa.io/get-pip.py
after that unzip/untar packages and run:
python get-pip.py --no-index --find-links=/path/to/pip-and-setuptools
or alternatively trying:
python setup.py install when running in unpacked folders
