Error installing scipy with pip - python

I have tried installing scipy using pip install scipy. I have installed all the dependencies, gcc-fortran, lapack-devel, blas-devel but to no avail. I created my virtual environment with pyvenv-3.4. Anytime I try installing scipy it hangs after these two lines
Building wheels for collected packages: scipy
Running setup.py bdist_wheel for scipy
On one trial, I waited all night and it did not install. My OS is CentOS-7. Thanks for your help.
After getting some help, I tried easy_install scipy. Same problem it stops somewhere and just hangs. I have to depress Ctrl+C to escape. How do I finish installing or reinstall it? Thanks.
Edit:
I finally fixed it by following the instructions here: http://chrisstrelioff.ws/sandbox/2014/06/04/install_and_setup_python_and_packages_on_ubuntu_14_04.html

I would recommend to use Anaconda. It comes with many packages for scientists. SciPy works out of the box. Just install as user not root. It comes with conda which is an improved virtualenv.
If you don't want all packages of Anaconda use Miniconda
You can create a new environment and install scipy:
conda create -n my_project python=3.4
source activate my_project
conda install scipy
No compilation involved.

pip install scipy==1.4.1 on mac os

I have created a new virtual environment with nothing else in it and I try to install
pip install scipy==1.4.1
However this returns the following error
ERROR: Failed building wheel for scipy
Failed to build scipy
ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly
This has been solved before by running
pip install --upgrade pip
However this does not work for me and I get the same error as before. If however I try and install the latest version of scipy there are no issues. Does anyone know a way around this? Maybe I need a less up to date version of python but I am really not sure.
Probably your python version is too new for this specific scipy version, use a earlier python version to solve the problem.
Install a specific python version (i.e. 3.7.4) from https://www.python.org/downloads/
Create virtual environment with pipenv:
pipenv shell --python 3.7.4
(and activate virtual environment)
Install scipy==1.4.1

Pytorch won't install in PyCharm on MacOS

I'm new to the MacOS and I have recently downloaded PyCharm on it. I was able to successfully install some packages like numpy, matplotlib, sympy, etc. However, Pytorch won't get installed; not through PyCharm nor through the Terminal. These are the commands I tried in the Terminal (other than attempting to install them directly from PyCharm):
pip install torch
pip install torch torchvision torchaudio
I could post the error messages but some are quite lengthy :(
I'm using Python 3.9 interpreter with pip on the latest version (20.2.4) (everything else is also up to date). Running this on the new Mac Mini (running the M1 chip).
Any ideas on what I should do? Thanks!!!
Try building from the source code, run these commands
git clone https://github.com/pytorch/pytorch.git
cd pytorch
git submodule update --init --recursive
python3 setup.py build
python3 setup.py install
Are you using a venv? If so you could try checking the box "install to user's site packages directory" in the Project Interpreter settings when you add a package.

Unable to install openpifpaf and pycocotools with pip. ERROR: Failed building wheel for openpifpaf/pycocotools

Configuration:
macOS 10.14
Python 3.7.1
I am trying to install pycocotools and openpifpaf by issuing this command that should install openpifpaf and pycocotools:
pip3 install 'openpifpaf[train,test]'==0.5.2
as it is mentioned in my project work.
I looked at previous similar questions and tried to update setuptools and wheels, it did not help.
Basically the final message error are:
ERROR: Failed building wheel for pycocotools
ERROR: Failed building wheel for openpifpaf
I can provide more details on the error if necessary, I have no idea of how to fix it.
pycocotools is a bit special. It requires pre-installed Cython and numpy and pure pip cannot handle an order in the dependencies. You have to run pip3 install numpy cython before you can install openpifpaf with the train dependency.
I hope you find openpifpaf useful. Feel free to open an issue for this kind of question; I would have seen that earlier.
I had the same error for when I tried pip install pycocotools to my virtual environment venv. Installing pycocotools has other package dependencies - I'm not sure which exactly but it's among these here which are installed in venv. Probably just numpy and cython are necessary, but I haven't tested that.
Make these dependencies findable by adding venv to the PYTHONPATH in ~./bash_profile:
export PYTHONPATH="${PYTHONPATH}:path/to/venv"

Error installing geopandas:" A GDAL API version must be specified " in Anaconda

This error raised while installing geopandas. I've looking for its solution on the web, but none of them really explain what happened and how to solve it..
This is the full error:

If you still have problems, consider uninstalling the above (pip uninstall) and reinstalling.
I solved this problem by running the following commands:
pip install pipwin

Geospatial Data Abstraction Library (GDAL) is a library designed for vector geospatial data formats. It's a prerequisite for installing Fiona, the Python API for OGR (which doesn't really stand for anything), which is in turn a prerequisite for Geopandas. On UNIX-like systems the gdal-config script tells Fiona stuff about your particular gdal installation.
It seems that your gdal-config is not in one of the usual places on your PATH, so Fiona was unable to find it.
If you're using Anaconda, best is to remove gdal with conda remove gdal and then do a fresh conda install geopandas.
As a general rule, if you're using Conda you should never use pip to install something inside it unless you're absolutely sure conda offers no support for it. (Many package can be found on conda by specifying the right channel - -c argument.) And specifically in the case of geopandas, the maintainers recommend using conda over pip, since pip requires you to install the dependencies correctly.
I had a lot of issues myself installing geopandas, mostly showing error when downloading fiona and gdal. I did every step above and did a conda install geopandas but failed. The only thing worked for me is to install fiona and gdal wheel separately.
go to the link by Christoph: gohlke:https://www.lfd.uci.edu/~gohlke/pythonlibs/#fiona
You can search for fiona and gdal wheel files. Make sure you choose the file as per your python version, if it is 3.7 then there would be cp37.
Download the file
go to command prompt, put cd and then pip install , install GDAL wheel file, then fiona, then just do pip install geopandas.
This solution worked for me.
To install gdal, I followed the following steps:
downloaded the version that satisfies my computer (64 bit) from
https://www.lfd.uci.edu/~gohlke/pythonlibs/ . The file was GDAL-3.1.4-cp37-cp37m-win_amd64.whl
Put the file in a folder on the desktop.
From cmd, i moved to that directory and executed python -m pip install GDAL-3.1.4-cp37-cp37m-win_amd64.whl
This is followed by installing fiona the same way: python -m pip install Fiona-1.8.18-cp37-cp37m-win_amd64.whl
For shapely, i executed conda install -c conda-forge shapely
After that, i was able to install keplergl as usual: pip install keplergl
install descartes: conda install -c conda-forge descartes (or python -m pip install descartes).
In this way, i didn't have to play around with the 'Environmental Variables' as this may affect other programs
Cheers..
Installing geopandas
Geopandas has very complex multi-language dependencies, some of which need to be built with consistent compiler versions across packages. Because of this, the geopandas docs recommend installing using conda in a new environment using conda-forge only. Here are some general best practices to keep in mind:
conda is the recommended installation method. You can install geopandas from pip or source, but it's going to be a bumpy ride and it's not recommended. If you're installing conda for the first time, I recommend you start with miniconda (or better yet miniforge, a conda-forge-first miniconda variant), not anaconda, to keep your base env lean.
When using conda, you should not mix and match conda channels.
When installing geopandas, try creating a fresh environment rather than installing into your base environment. If you have anaconda installed, it comes with a large number of packages from the "defaults" channel installed in your base environment. I recommend deleting anaconda and installing miniconda, then installing into a new environment.
Try to create a new environment with everything you plan to use all at once rather than iteratively modifying the environment. In other words, if you want to use geopandas with scikit_learn, folium, and rasterio, install them together with a single conda create command
As a last resort, delete your conda installation and re-install miniconda. Desperate times call for desperate measures, and this usually resolves gnarly installation nightmares.
To create a fresh conda environment in which you install all necessary dependencies at the same time, using the conda-forge channel:
conda create -n my-geopandas-env -c conda-forge geopandas [all other packages you need]
For example, I might set up an environment with something along the lines of...
conda create -n my-geopandas-env -c conda-forge python=3.9 \
ipython ipykernel geopandas scipy seaborn fiona matplotlib cartopy
Bundling your installations into a single environment creation step like this reduces the chance of packages falling out of sync. To speed this process up, you could first install mamba or mambaforge, a faster drop-in replacement for conda, into your base environment and then run the above commands with mamba instead of conda.
Generally, it's best to avoid installing much of anything in your base environment (cross-environment system utilities like mamba are some of the few exceptions). If you already have a complex base environment (maybe you started with anaconda rather than miniconda) this may be the time to delete your entire conda installation and start from scratch (I know that's terrifying... sorry! but it'll save you heartache in the future). mamba is great for speeding this process up.
Connecting your editor to the conda environment
Once you have installed all of the packages you need, activate your environment with conda activate my-geopandas-env. See the conda guide to managing environments for more info.
Jupyter/ipython
Some editors/IDEs including jupyter require additional packages - jupyter requires that ipython and ipykernel be installed in order to load the environment within the notebook or editor - that's why I included ipykernel in my list above. See the ipykernel docs for more info.
Other IDES
To link this environment to an IDE such as VSCODE, spider, etc., find the location of this python version with conda run -n my-geopandas-env which python then point your editor to this python executable. Check the docs of your specific editor to get more targeted info about how to set up a conda environment for use with your editor:
Spider: FAQ on using an existing environment and Spider wiki guide to working with packages and environments
VSCode: Using python environments in vscode
PyCharm: Configure a conda virtual environment
I don't have conda installed, then using just pip I followed these steps:
Download GDAL and Fiona wheels directly on:
GDAL: https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal
FIONA: https://www.lfd.uci.edu/~gohlke/pythonlibs/#fiona
Then:
pip install <gdal.whl>
pip install <fiona.whl>
In my case I did pip install GDAL-3.4.1-cp38-cp38-win_amd64.whl and Fiona-1.8.21-cp38-cp38-win_amd64.whl. Where cp38 stands for python 3.8.
After that you are able to install geopandas with pip as well.
pip install geo pandas
For me, the only solution was to install the ready binaries from here
https://www.lfd.uci.edu/~gohlke/pythonlibs/#gdal
Then just install locally
pip install GDAL-3.1.4-cp38-cp38-win_amd64.whl
One way in which I could install geopandas was through the Anaconda Navigator. Get into the environment and install the package 'geopandas'. After that I could import the geopandas package in spyder
I will add
!pip install descartes
to #JDOaktown list.
I started with pip install geopandas and got the error, but later tried with conda install --channel conda-forge geopandas and the error disappeared.
Successfully installed in RHEL 7.8.
It automatically downloaded the required packages. This might be helpful
Installing collected packages: certifi, pyproj, shapely, attrs, click, click-plugins, munch, cligj, fiona, geopandas

If you want to install GDAL, Geopandas, Shapely, Fiona etc in a windows Virtual Environment download .whl files for all of them and first install GDAL using
pip install gdal-.whl
Following this command edit the activate.bat file in you venv\Scripts folder and add
GDAL_CONFIG = \venv\Lib\site-packages\osgeo
Then you can install rest using pip install
I started off with a clean environment gdal_test in Conda environments, but made the mistake of using the old activate gdal_test instead of conda activate gdal_test. This made Conda Environment resolving take forever, which is why I resolved to other methods at first.
Takeaway: let conda handle it, with a proper new environment.
I ran into this problem not with anaconda/windows, but with python:3.6 Docker image. Google search always led me to this question, so I think I will share how I resolve my issue in case others also end up here.
Based on here, you need to install system relevant packages in the Dockerfile before running pip install geopandas or pip install requirements.txt:
RUN apt-get update && apt-get install -y --no-install-recommends \
build-essential \
libatlas-base-dev \
libgdal-dev \
gfortran
The following worked on macOS:
brew install gdal --HEAD
Verify the installation by running gdal-config --version
Following that pip installation as normal worked without a problem.

Stuck when install scipy in CentOS

Environment is Python 3.5 and CentOS 7.0 in VPS (XEN).
I use IUS repository for CentOS7 to install Python 3.5 and corresponding devel, setuptools packages.
Then upgrade pip3.5 itself by
sudo pip3.5 install upgrade pip
Numpy and Matplotlib can be installed by pip 3.5 without any problem.
sudo pip3.5 install numpy
sudo pip3.5 install matplotlib
But when I try to install scipy, it got stuck at the step running setup.py like forever. Only way to get rid of this is Ctrl+C. Tried several times, even reinstall CentOS and compile Python3.5 from source code. Always the same issue happens.
Collecting scipy

Could someone help me out please?
update (Feb 9th 2016):
A 1.5GB swapfile is created manually, which is none originally. Then after about 2 hours waiting, it is finally installed. I guess the relatively low performance of server leads to this problem.
