At first, I was trying to install evo (a package for SLAM research) from source and I encountered an error:
ModuleNotFoundError: No module named 'numpy'
So then I tried to install numpy using pip install numpy. However I encountered another error:
SystemError: Cannot compile 'Python.h'. Perhaps you need to install python-dev|python-devel.
Finally, I tried to install python-dev using sudo apt-get install python-dev, and I found out it has been installed already. So I don't know where the problem is.
My default python version is 3.8.16
Could anyone help me with this issue?
maybe conda could install it?
conda install -c anaconda numpy
it isn't generally ideal to mix conda and pip, but it should still install numpy successfully.
Run pip3 install --upgrade pip and try again.
If it doesn't work, try sudo apt-get install pypy-dev instead of python-dev.
You can also try sudo apt-get install python3-numpy
I am trying to get started with python on VS Code but I keep getting this error when I want to install the matplotlib library.
Consider using the --user option or check the permissions.
pip install -U --upgrade pip
I tried a lot of different ones but the one below worked for me
pip3 install --upgrade pip --user
Three things to do:
Run this in your bash terminal
python3 pip install --upgrade pip
Configure your VS Code environment for python 3.x
Run your file using python3 [filename.py]
If the above suggestion fails, you should try:
pip install --upgrade pip
I added the folder than tried pip install --upgrade pip and it worked. You may have to show your hidden folders to follow the path.
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases. To fix this problem, I'm trying to install it using this command:
python -m pip install --upgrade pip setuptools virtualenv)
I am attempting to install matplotlib and scipy to python, and using pip to do so. However when I attempted to install scipy with pip install scipy --myuser I received the message:
invalid requirement '--myuser'
Previously I had installed numpy using pip with
python get-pip.py —myuser
and
pip install numpy —myuser
This worked fine, so I am unsure what the problem is here.
This is frustrating as I would like to use python from the terminal rather than from my Windows desktop.
If you want to install to user try the below mentioned command:
pip install --user scipy
Here is the help from pip command:
pip install --help
--user Install to the Python user install directory for
your platform. Typically ~/.local/, or
%APPDATA%\Python on Windows. (See the Python
documentation for site.USER_BASE for full
details.)
You should be able to install it without the use of the --myuser argument.
sudo python3 -m pip install scipy
sudo python3 -m pip install matplotlib
or all in one
sudo python3 -m pip install scipy matplotlib
Try this:
sudo python3 -m pip install scipy matplotlib
I have been trying to install matplotlib on offline linux system without much success.
I have tried:
python2.7 setup.py build
It then tries the following:
Downloading http://pypi.python.org/packages/source/d/distribute/distribute-0.6.28.tar.gz
The same happens with setup.py install.
How can I get it to install without an internet connection?
I use Python 2.7.12
Go to Matplotlib pypi package index and download the appropriate file for your system.
Then use:
$ sudo apt-get install python-setuptools build-essential
$ pip install wheel_file.whl
you might have to use sudo with this command.
Download the matploitdb wheel
"http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib"
Then do,
pip install matploitdb_wheel.whl
It is possible to install NumPy with pip using pip install numpy.
Is there a similar possibility with SciPy? (Doing pip install scipy does not work.)
Update
The package SciPy is now available to be installed with pip!
Prerequisite:
sudo apt-get install build-essential gfortran libatlas-base-dev python-pip python-dev
sudo pip install --upgrade pip
Actual packages:
sudo pip install numpy
sudo pip install scipy
Optional packages:
sudo pip install matplotlib OR sudo apt-get install python-matplotlib
sudo pip install -U scikit-learn
sudo pip install pandas

An attempt to easy_install indicates a problem with their listing in the Python Package Index, which pip searches.
easy_install scipy
Searching for scipy
Reading http://pypi.python.org/simple/scipy/

Reading http://new.scipy.org/Wiki/Download
All is not lost, however; pip can install from Subversion (SVN), Git, Mercurial, and Bazaar repositories. SciPy uses SVN:
pip install svn+http://svn.scipy.org/svn/scipy/trunk/#egg=scipy
Update (12-2012):
pip install git+https://github.com/scipy/scipy.git
Since NumPy is a dependency, it should be installed as well.
In Ubuntu 10.04 (Lucid), I could successfully pip install scipy (within a virtualenv) after installing some of its dependencies, in particular:
$ sudo apt-get install libamd2.2.0 libblas3gf libc6 libgcc1 libgfortran3 liblapack3gf libumfpack5.4.0 libstdc++6 build-essential gfortran libatlas-sse2-dev python-all-dev
To install scipy on windows follow these instructions:-
Step-1 : Press this link http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy to download a scipy .whl file (e.g. scipy-0.17.0-cp34-none-win_amd64.whl).
Step-2: Go to the directory where that download file is there from the command prompt (cd folder-name ).
Step-3: Run this command:
pip install scipy-0.17.0-cp27-none-win_amd64.whl
I tried all the above and nothing worked for me. This solved all my problems:
pip install -U numpy
pip install -U scipy
Note that the -U option to pip install requests that the package be upgraded. Without it, if the package is already installed pip will inform you of this and exit without doing anything.
If I first install BLAS, LAPACK and GCC Fortran as system packages (I'm using Arch Linux), I can get SciPy installed with:
pip install scipy
On Fedora, this works:
sudo yum install -y python-pip
sudo yum install -y lapack lapack-devel blas blas-devel
sudo yum install -y blas-static lapack-static
sudo pip install numpy
sudo pip install scipy
If you get any public key errors while downloading, add --nogpgcheck as parameter to yum, for example:
yum --nogpgcheck install blas-devel
On Fedora 23 onwards, use dnf instead of yum.
For the Arch Linux users:
pip install --user scipy prerequisites the following Arch packages to be installed:
gcc-fortran
blas
lapack
Addon for Ubuntu (Ubuntu 10.04 LTS (Lucid Lynx)):
The repository moved, but a
pip install -e git+http://github.com/scipy/scipy/#egg=scipy
failed for me... With the following steps, it finally worked out (as root in a virtual environment, where python3 is a link to Python 3.2.2):
install the Ubuntu dependencies (see elaichi), clone NumPy and SciPy:
git clone git://github.com/scipy/scipy.git scipy
git clone git://github.com/numpy/numpy.git numpy
Build NumPy (within the numpy folder):
python3 setup.py build --fcompiler=gnu95
Install SciPy (within the scipy folder):
python3 setup.py install
In my case, it wasn't working until I also installed the following package : libatlas-base-dev, gfortran
sudo apt-get install libatlas-base-dev gfortran
Then run pip install scipy
install python-3.4.4
scipy-0.15.1-win32-superpack-python3.4
apply the following commend doc
py -m pip install --upgrade pip
py -m pip install numpy
py -m pip install matplotlib
py -m pip install scipy
py -m pip install scikit-learn
The answer is yes, there is.
First you can easily install numpy use commands:
pip install numpy
Then you should install mkl, which is required by Scipy, and you can download it here
After download the file_name.whl you install it
C:\Users\****\Desktop\a> pip install mkl_service-1.1.2-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\mkl_service-1.1.2-cp35-cp35m-win32.whl
Installing collected packages: mkl-service
Successfully installed mkl-service-1.1.2
Then at the same website you can download scipy-0.18.1-cp35-cp35m-win32.whl
Note:You should download the file_name.whl according to you python version, if you python version is 32bit python3.5 you should download this one, and the "win32" is about your python version, not your operating system version.
Then install file_name.whl like this:
C:\Users\****\Desktop\a>pip install scipy-0.18.1-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\scipy-0.18.1-cp35-cp35m-win32.whl
Installing collected packages: scipy
Successfully installed scipy-0.18.1
Then there is only one more thing to do: comment out a specfic line or there will be error messages when you imput command "import scipy".
So comment out this line
from numpy._distributor_init import NUMPY_MKL # requires numpy+mkl
in this file: your_own_path\lib\site-packages\scipy__init__.py
Then you can use SciPy :)
Here tells you more about the last step.
Here is a similar anwser to a similar question.
Besides all of these answers,
If you install python of 32bit on your 64bit machine, you have to download scipy of 32-bit irrespective of your machine.
http://www.lfd.uci.edu/~gohlke/pythonlibs/
In the above URL you can download the packages and command is: pip install
For gentoo, it's in the main repository:
emerge --ask scipy
You can also use this in windows with python 3.6 python -m pip install scipy
