I have macbook air m1 and I can't install python modules like numpy, matplotlib.
I install python3.8 with homebrew then install virtaulenv. In venv, when I run 'pip install numpy' the error shows up:
'... ERROR: Failed building wheel for numpy
Failed to build numpy
ERROR: Could not build wheels for numpy which use PEP 517 and cannot be installed directly'
I tried 'pip install --upgrade pip setuptools wheel' doesn't work. Please help.
Install python 3.9.1 from python.org (ARM version)
Then, for Numpy:
python3 -m pip install cython
python3 -m pip install --no-binary :all: --no-use-pep517 numpy==1.20rc1
Then, for matplotlib:
brew install libjpeg
python3 -m pip install matplotlib
This works for me on a Mac min with Apple Silicon.
No luck for SciPy yet, though.

I've installed several Python modules from PyPi globally on Mac OS using pip3. Running pip3 list confirms that they are installed:
user#users-MacBook-Pro SER-neural-net % pip3 list
Package Version
------------------ ---------
appdirs 1.4.4
audioread 3.0.0
...
librosa 0.9.2
numpy 1.23.4
pip 22.3.1
scikit-learn 1.1.3
scipy 1.9.3
sklearn 0.0.post1
sounddevice 0.4.5
soundfile 0.11.0
torch 1.13.0
...
From the integrated terminal in VS Code where I am running the notebook, I have run the following commands to determine which Python interpreter to use:
user#users-MacBook-Pro SER-neural-net % which pip3
/usr/local/bin/pip3
user#users-MacBook-Pro SER-neural-net % which python3
/usr/local/bin/python3
user#users-MacBook-Pro SER-neural-net % python3 --version
Python 3.7.9
I have selected the appropriate interpreter at the top right of Jupyter Notebook view in VS Code:
But the modules confirmed to be installed for this interpreter are not found:
What has gone wrong?
use this:
python3 -m pip install --user (library)
for example:
python3 -m pip install --user pandas
I can't install pillow on my computer anymore. When I tried pip install Pillow, I get warnings and then 2 errors :
ERROR: Could not find a version that satisfies the requirement pillow (from versions: none)
ERROR: No matching distribution found for pillow
I saw a lot of people in the same case and I tried all the solutions but nothing worked. Do you have any idea on how to re-install pillow?
Install with whatever you use to run Python, not pip directly. For example:
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
See https://snarky.ca/why-you-should-use-python-m-pip/ for more details.
I am trying install scipy in FreeBSD 13. I have built python 3.10 on FreebSD 13 and managed to install pandas, matplotlib and numpy on a virtual environment which has python 3.10. However, when I try to install sklearn or scipy I get an error saying scipy could not be installed.
Here it is below for when doing pip install scipy. I get the same error more or less when trying to install sklearn.
ERROR: Failed building wheel for scipy
Failed to build scipy
ERROR: Could not build wheels for scipy, which is required to install pyproject.toml-based projects

Reuse system package
# install system-wide version in site-packages
doas pkg install py38-scipy-1.8.0
# create a virtualenv with site-packages included
python -m venv --system-site-packages .venv
Drawback is you'll get all packages from site-packages, however you can tackle that by
doas pkg install py38-scipy-1.8.0
python -m venv .venv
YOUR_PYTHON_VERSION= SET IT HERE
ln -s $(python -c 'import lxml, os.path; print(os.path.dirname(lxml.__file__)') ./.venv/lib/$YOUR_PYTHON_VERSION/site-packages

Regular Installation (TODO)
Haven't figured out it yet, but maybe someone else will, so putting here 2 links which might be helpful

Have you tried to install scipy from freebsd ports? The freebsd ports contain patches to make the code compile on FreeBSD.
After upgrading my pip to version 10 using pip3 install --upgrade pip and above I cannot I want to install/upgrade PyPi packages using pip3 install PyPiPackageName as I get the following error:
from pip import main
ImportError: cannot import name main
I wonder how I can install PyPi packages using pip when I'm using new versions of pip? I've seen some people use pyhton3 to do this but doing python3 -m pip install --upgrade pip gave me the following error and I cannot upgrade pip to higher versions:
/usr/bin/python3: No module named pip
Before doing python3 -m pip install --upgrade pip I do python3 -m pip install -U pip and I get the following error:
/usr/bin/python3: No module named pip
So I'm confused on what I need to do to be able to upgrade or install PyPi packages.
In addition to executing the following:
curl https://bootstrap.pypa.io/get-pip.py | python3.6
I also had to make sure python3 is using Python 3.6 otherwise Python 3.5 is used (which does not come with pip by default). So I did the following and things work fine now:
ln -s /usr/bin/python3.6 /usr/local/bin/python3
I cant install the shapely module in my anaconda prompt.
pip install --upgrade setuptools
pip install shapely
Command "python setup.py egg_info" failed with error code 1 in C:\Users\renau\AppData\Local\Temp\pip-install-27xf59zz\shapely\
Any solutions?
If you are using Anaconda, then it would probably be best to use:
conda install shapely
i guess you are using Windows ?
if so, you can't install shapely directly via pip
here's the steps:
go to this site and download desired version of shapely
run this script
pip install Shapely‑1.6.4.post1‑cp36‑cp36m‑win_amd64.whl
here i'm going to install Shapely version 1.6.4 for python 3.6 running in Windows 64bit
sudo apt-get install python-shapely
on Python 3
sudo apt-get install python3-shapely
