I'm quite new to machine learning and when I tried to install numpy and this happended Can you guys help me fix this. I'm using python 3.10.0
ERROR: Failed building wheel for numpy
Failed to build numpy
ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects
I faced the same issue, I have a macos high sierra with python 3.10 and I have the same error while installing numpy in pip.
I managed to solve the problem by installing not the newest numpy 1.22.2 in pip. I install version 1.22.1.
Command:
pip install numpy==1.22.1
Numpy has not yet released a precompiled wheel for Python 3.10. What you can do, is downgrade to python 3.9. If you don't want to do this, you can try the unofficial wheels available here.
These are the important ones you should look for:
numpy‑1.21.2+mkl‑cp310‑cp310‑win_amd64.whl
numpy‑1.21.2+mkl‑cp310‑cp310‑win32.whl
(Choose based on your OS architecture)
Then download the file, go to your downloads folder, and run pip install "<your_filename_choice>.whl").
You could also just use the pipwin module.
Do this:
pip install pipwin
and then
pipwin install numpy
Note that wheels have been available for Python 3.10 since 5th November, see:
https://pypi.org/project/numpy/#files
specifically, I can see Python wheels for labelled as version cp310 (i.e. CPython 3.10) for Linux, Mac and Windows.

I'm working with Python 3.8.7 on a computer having CentOS Linux release 7 (Core) operating system.
I have to install the numpy package.
I tried to follow these instructions, by running the command:
pip install numpy
Unfortunately, I got the following error:
ERROR: Could not build wheels for numpy, which is required to install pyproject.toml-based projects
Any idea on how to solve this problem? Thanks
Look here: https://github.com/numpy/numpy/issues/20039, try to install another python version such as python 3.9 use pyenv to do that https://github.com/pyenv/pyenv

I can't install the "numba" package via "pip". I want to install the "numba" package, but an error appears every time
please check your python and numpy version . Numba is compatible with Python 3.6 or later, and Numpy versions 1.15 or later. Please check the documentation
https://numba.pydata.org/numba-doc/latest/user/installing.html
Installing using pip on x86/x86_64 Platforms
Binary wheels for Windows, Mac, and Linux are also available from PyPI. You can install Numba using pip:
$ pip install numba
When I try to install scipy for 3.4 it throws this error when I run this command:
sudo pip3.4 install scipy
https://www.pastiebin.com/5a7c65d7e44fe
I was able to get it to install with Python 3.6 but not 3.4.. which I need.
Installing Scipy or Numpy from scratch is usually hard work. At best try a distribution that already has it installed (WinPython, Anaconda). If you are on Linux install the packages that come with your distro. On Windows you can also grab the wheels at Gohlke.
I am using 32 bit cmd, 64 bit windows, python 2.7
when I type the command pip install statsmodels
I get the following error for some module of scipy...
Failed building wheel for Scipy Failed cleaning build dir for scipy
install numpy
pip install numpy
If you face installation issues for numpy, get the pre-built windows installers from http://www.lfd.uci.edu/~gohlke/pythonlibs/ for your python version (python version is different from windows version).
numpy 32-bit: numpy-1.11.1+mkl-cp27-cp27m-win32.whl
numpy 64-bit: numpy-1.11.1+mkl-cp27-cp27m-win_amd64.whl
Later you require VC++ 9.0, then please get it from below link Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpython27
Then install
Get the pre-built windows installers from http://www.lfd.uci.edu/~gohlke/pythonlibs/ for your python version (python version is different from windows version).
Scipy 32-bit: scipy-0.18.0-cp27-cp27m-win32.whl
Scipy 64-bit: scipy-0.18.0-cp27-cp27m-win_amd64.whl
If it fails saying whl is not supported wheel on this platform , then upgrade pip using python -m pip install --upgrade pip and try installing scipy
Now try
pip install scipy
Then try
pip install statsmodels
It should work like a charm
I have tried to write this on cmd.exe and it worked.
pip install statsmodels==0.6.0
install statsmodels for python 2.7 in windows
An easier way to install python libraries on Windows with C/C++/Fortran/... dependencies is to use conda. conda is available in MiniConda or Anaconda continuum products.
Another easy way to install scientific python libraries on windows is to use Christoph Gohlke's windows web page.
If you have no much idea about all of them and how to manage dependencies on windows I recommend you uninstalling your Python and installing anaconda. Anaconda already has Numpy, Scipy, Matplotlib,..., and statsmodels pre-installed (see the list of the packages included in the anaconda distribution).
Make sure you are using the latest version of pip
To check which version you are using try:
pip --version
To install statsmodels you can either go to cmd.exe or if you are using python pycharm use "Terminal Window" and type:
pip install statsmodels==0.9.0
I am trying to install Numpy on Python 2.7 and I am using Windows 8.1. When I run Numpy from this link it says, "Python 2.7 required, which was not found in the registry ". How can resolve this issue, I already installed Python 2.7?
For Windows, you should check out Chris Gohlke's page:
http://www.lfd.uci.edu/~gohlke/pythonlibs
He has some Numpy builds there for Python 2.7.
You can first install wheel using pip.
pip install wheel
Then download the .whl file for Numpy from Chris Gohlke's page.
Then go to the directory where you downloaded the package.whl file in cmd and do the following
pip install package_you_downloaded.whl
I experienced a similar broken toolchain error while installing Numpy. You can check it here.
I changed to anaconda a while ago and in my mind its the best and most dynamic package manager for all platforms.
http://docs.continuum.io/anaconda/install.html
correct command after installing pip is:
python -m pip install numpy
You should use pip to install Numpy and any other librarys
check this for how to install pip
after installing, go to your command line and enter
pip install numpy
