Trouble installing scipy on Mac OSX Lion - numpy

I've installed new instance of python-2.7.2 with brew. Installed numpy from pip, then from sources. I keep getting
numpy.distutils.npy_pkg_config.PkgNotFound: Could not find file(s) ['/usr/local/Cellar/python/2.7.2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/numpy/core/lib/npy-pkg-config/npymath.ini']
when I try to install scipy, either from sources or by pip, and it drives me mad.
Scipy's binary installer tells me, that python 2.7 is required and that I don't have it (I have 2 versions installed).

EPD distribution saved the day.

Installing Pythonnet package on MacOS v12.4

Has anyone installed Pythonnet on Python 3.10.0 (was pre-installed with Mac OS)? When I try to install Pythonnet through PIP, it complains that there is some issue with the package, and not with PIP!! After searching a bit on Google , I found that Pythonnet is currently not supported on Python 3.10.
So the next step was to install an older version (supported) of Python e.g. 3.7 on Mac and then make it the default Python environment. However, even after using the right set of commands, I'm unable to do switch from 3.10 to 3.7.
enter image description here
Can someone please tell me where am I going wrong?
Try installing a preview with --pre pip parameter. Python.NET 3.0.0 is currently in preview and is about to be released, it supports Python 3.10.

Does tensorflow support Python 3.6.4 on Windows?

I'm running a Windows computer with just a CPU (no GPU). When I run pip install tensorflow -vvv in order to see what pip is doing, it lists a lot of links, but for all of them, it says "Skipping link ... it is not compatible with this Python."
Does tensorflow support Python 3.6.4 on Windows? If so, what binary URL should I use to install it?
(I previously installed with this version due to reading this, but ran into this error without the DLL load failed message, so I'm wondering if there's a better version I should use.)
Also, I'm aware that Tensorflow says they support Python 3.x, but right now it hasn't been working for me.
You have probably installed Python 32bits, you need the 64bits version

Tensorflow installation

Upon trying to install Tensorflow for conda environment, I encountered with the following error message, without any progress:
tensorflow-1.1.0-cp35-cp35mwin_amd64.whl is not a supported wheel on this platform
Have you tried uninstalling and re-installing TensorFlow using pip within your Conda environment? I.e.:
pip uninstall tensorflow
Followed by:
pip install tensorflow
If it doesn't work, the issue may be with your Python installation. TensorFlow only supports 64-bit Python 3.5+ on Windows (see more info here).
Perhaps you have Python's default installation, which comes in a 32-bit version. If that's the case, you can download the 64-bit Python 3.5 or later from here to run in your Conda environment and then you should be able to install/run TensorFlow without any issues.
Make sure that the Python version installed in the Environment is 3.5 not 3.6. Since 3.6 was released Conda automatically sets that version as default for python 3. However, it is still not supported by Tensorflow.
You can work using tensorflow library along with other essential libraries using the Dockerfile. Using Docker for environment are a good way to run experiments in reproducible manner as in this blog
You can also try using datmo in order setup environment and track machine learning projects for making it reproducible using datmo CLI tool.

Python Packaging Fix: Understand Differences between Wheel and Egg; How to get local fix to wider audience?

I'm trying to understand why the easy_install of pyicu works and pip install doesn't (see below). also trying to understand "What is the difference between a PyPi project with a universal wheel and one without?" Will installs be "easier?". If so, will this merge request solve the problem of polyglot not installing on an Anaconda machine?
Need help/advice/solutions on how to best resolve python project install issue that is tied to underlying dependencies. I have two local fixes in GitHub Gists but would like to know the best way to have this fix "out there" so people like me can find it. What is the normal Python Community approach? The problem centers around three projects:
polyglot - a python multilingual NLP toolkit
pyicu - Python extension wrapping IBM's International Components for Unicode C++ library (ICU).
pycld2 - CLD (Compact Language Detection) library as maintained by Dick Sites
The goal:
Install polyglot on a MacOSX computer running Python Anaconda Distribution
Make the fix I found available to everyone; lots of issues published about the problem.
Here's the error trace:
The Problem (Lots of them):
Core polyglot dependency, pyicu, does not properly install when you use pip install. Discovered you must use easy_install for it build properly and work on MacOSX. If you don't use the easy_install, you get:
polyglot requires icu 54.1.1 to run in Anaconda, but...
Homebrew, the MacOSX tool to install icu, only installs version 58.1. That version is too new. Old stackoverflows advise brew install icu4c to fix problem, but Homebrew evolution makes that advice obsolete now.
pyicu does not have a universal wheel; but I created a merge request to add one to pyicu. Only way to fix this is with this channel's icu, https://anaconda.org/ccordoba12/icu. conda install icu will not work, but that's the normal conda way of doing things.
*pycld2 - CLD (Compact Language Detection) becomes a problem because after I build the wheel file locally, have to download the project and run setup.py install locally. There has to be a better way to do this right?
What I've Done to Solve the problem (should I do more, what should I do next?)
Created two Gists that can successfully install polyglot on a Mac running Anaconda for Python 2.7 or Python 3.5
Python 2.7 fix
Python 3.5 fix
created the merge request for pyicu
Both Gist fixes work. But, is this error in install tied to the wheel? If I installed pyicu with easy_install, the install works. But, with pip, it doesn't?
What are the steps to take in the Python community to fix it so people can find the solution or just pip install with no problems?
I did a test, and if the wheel file is built, the pip works with no issues.

Installing Pandas using Pip on Windows 7

Having issues installing Pandas with Pip on Windows 7.
EDIT:
Seems like I did not have Microsoft Visual C++ installed.
The much easier approach, as someone kindly mentioned, was to install Anaconda and use it as the package manager as opposed to Python's native pip, although, for some packages (i.e PyBullet), you might have to default back to using Pip.
From your tags I guess you are using Windows as OS. Many people use Anaconda. It comes with many packages including pandas. The line is here It should be easy to install. Do you use any IDE?
