I am trying to install scipy package for python 2.7 in windows,
The process i followed is as follows:
downloaded a whl file scipy-0.17.1-cp27-cp27m-win32.whl from
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
tried to install by
pip install scipy-0.17.1-cp27-cp27m-win32.whl
error : Requirement 'scipy-0.15.1-cp27-none-win32.whl' looks like
a filename but the file does not exist
scipy-0.15.1-cp27-none-win32.whl is not a supported wheelon this platform.
then tried to install by
pip install file_location\scipy-0.17.1-cp27-cp27m-win32.whl.
error displayed :scipy-0.15.1-cp27-none-win32.whl is not a supported wheel on this platform.
Also i have already upgraded my pip command.
Can anyone suggest me out some valid solutions?
I Think the issue in Python interpreter variant 32 or 64.. if your python is 32-bit then use scipy-0.17.1-cp27-cp27m-win32.whl otherwise if your python is 64Bit then try scipy-0.17.1-cp27-cp27m-win_amd64.whl

From the past two days, I've been trying to install scipy from the wheel file available from http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy in my windows laptop 64 bit built and running Python 2.7.3. I tried running pip install scipy in the command window, it didn't work and the following error popped up in command prompt
and
I also tried typing
pip install scipy-version.whl
That didn't work too! and the same error popped up. I even updated my pip.
I read in some comments that pip doesn't work well for scipy installation. If so, what alternatives can you suggest? If not can you tell me the way to install using wheel scripts?
There are some issue while installing scipy using pip, please try using Anaconda python version which comes with all the libraries you can ever need instead of your default python.
Still if you want to use the default python refer here, as already answered here.
I'm using python 2.7.6 and in my code I have a line:
import psycopg2.extensions
which I've installed using pip. Next, my editor tells me, that psycopg2 requires python_ldap=2.4.19.
However, in the PyPI repository, there's only a 32 bit version, which doesn't work, since my Windows is 64 bit.
There's a 64 bit version of python_ldap=2.4.28, avaliable here, however running
pip install python_ldap-2.4.28-cp27-cp27m-win_amd64.whl
in the windows command line returns
python_ldap-2.4.28-cp27-cp27m-win_amd64.whl is not a supported wheel on this platform.
in red, which I guess is an error meassage.
So, in the end, what should I do to have the package installed on my laptop?
For anyone who's facing this, I solved this problem by installing the wheel from http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap.
Cheers.
EDIT: I did this on a 64 bit Windows 10 machine, but I presume the same solution applies to Windows 7.
$ python --version

pip install --only-binary :all: python_ldap-3.1.0-cp36-cp36m-win_amd64.whl
Make sure you choose the .whl file version matching the python install version
pip install --only-binary :all: python_ldap-3.1.0-cp36-cp36m-win_amd64.whl

As mentioned on the official website the unofficial package from on Christoph Gohlke’s page should work.
Latest update is from 3rd of July, so it seems to be pretty up to date.
I've been trying to install Python's matplotlib library for use with PyPlot, for use with Julia. I managed to get everything in place except for this one final library, and I feel as though I've hit a deadend trying to get it working.
When trying to install matplotlib (I've attempted using pip, regular python install, and easy_install), I get the following message at the very end of the install output, after which it is NOT installed:
* The following required packages can not be built:
* freetype, png
Confused about this, I looked around online and installed both of these (at least, what I think these were). One was the freetype project, and the other was LibPng, which was the closest thing I could find to a "png package" for windows or python in general.
This didn't initially work (for either of them), and I read somewhere that I needed a freetype.dll in my system32 folder. It was a long shot, but I went to where I installed freetype and pulled out the dll and renamed it, placing it in system32. This of course did not work (again, long shot).
Anyway, that's where I'm at. No idea where to go from here, and I'm unsure if I even grabbed the correct "packages" I should be using. Thoughts?
Use a more powerful installer
I would recommend to use Anaconda or Miniconda. In my experience with many Windows users, this is the simplest way to install packages such as matplotlib.
Anaconda
Anaconda comes with many packages for scientists. Matplotlib works out of the box. Just install as user not root.
Minoconda
If you don't want all packages of Ananconda use Miniconda
Conda
Both ways of installation (Anaconda or Miniconda) provide conda. It is an improved pip/virtualenv.
You can install matplotilb with this command:
conda install matplotlib
Enviroments:
You can create a new environment and install the packages you like:
conda create -n my_project35 python=3.5
activate my_project35
conda install matplotlib
or
conda create -n my_project27 python=2.7
activate my_project27
conda install matplotlib
Combine with pip
You can still use pip. conda "understands" what it is doing.
One snake is enough!
[This is for folks using the Linux Bash Shell on Windows 10.]
If you don't want to go the Anaconda route, you can install freetype (and png) by executing the following in the Windows 10 Bash shell:
sudo apt-get install freetype6-dev
The above command will also automatically install libpng. However, due to an error, the system will not 'realize' it has installed freetype, so you'll need to manually install pkg-config:
sudo apt-get install pkg-config
Thereafter you should be able to install matplotlib via pip without further incident.
sudo pip install matplotlib
I tired downloading matplotlib 2.2.2 with python 3.9.5, getting freetype & png errors for hours.
After downloading python 3.7.9 and removing python 3.9.5 from environment variables, installing matplotlib 2.2.2 worked with no problems!
Change your Python Version
Go to https://www.python.org/downloads/windows/, control-f search 3.7.9 and use the webinstaller. Follow all the recommended instructions
In pyvenv.cfg in your project directory switch version number to 3.7.9 and home to C:.....\Python37.
pip3 install alpaca-backtrader-api
I've been at this for nearly 2 hours and I just can't seem to get my head around it. I am a novice Pythoner, it would appear. I am trying to intsall lxml, (needed to install scrapy). I have tried multiple methods (see my other current quesitons).
Currently I am trying the following.
I downloaded the lxml win 32 file for python 2.7 from this website:
https://pypi.python.org/pypi/lxml/3.4.4#downloads
The LXML Binaries are also available here: "http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml"
I download the .whl file.
I then open up CMD, and CD to my download folder. Once in that folder I run the following command (as per the answer to this question here: How do I install a Python package with a .whl file?)
pip install lxml-3.4.4-cp27-none-win32.whl
This is the output:
C:\Users\Charles\Downloads\python>pip install lxml-3.4.4-cp27-none-win32.whl
Downloading/unpacking lxml-3.4.4-cp27-none-win32.whl
Could not find any downloads that satisfy the requirement lxml-3.4.4-cp27- none
-win32.whl
No distributions at all found for lxml-3.4.4-cp27-none-win32.whl
Storing complete log in C:\Users\Charles\AppData\Roaming\pip\pip.log
Can anyone help me figure out what this means/what is going on? How can I execute this file to install the lxml as needed?
Many thanks!!
Edit: I am using Windows 64 bit, but from this question here: "easy_install lxml on Python 2.7 on Windows" the file I have selected appears to be the correct one.
I am using Windows 64 bit and use Scrapy. It took a while for me to figure out the best way to set up my virtualenv because lxml would not simply pip install.
So I did somethine very similar to what you did but it looks at first glance we may just be using different sites. So try downloading this .whl from HERE. Specifically, for your specifications I believe, grab the one that reads
lxml-3.4.4-cp27-none-win_amd64.whl
and then just cd to the downloads folder and pip install lxml-3.4.4-cp27-none-win_amd64.whl
The first thing you should do is upgrade pip; the latest version is 8.0. Next, you need to install wheel support (this step may be redundant in later versions) and then finally install your wheel:
pip install --upgrade pip
pip install wheel
lxml needs a lot of source-level dependencies, which are difficult to install in Windows. This is why the project provides binary installers for Windows. You can download these from the pypi page for lxml. Make sure you choose the right version for your environment:
lxml-3.4.4.win32-py2.7.exe - for Python 2.7 running on Windows 32-bit
lxml-3.4.4.win32-py3.2.exe - for Python 3.2 running on Windows 32-bit
lxml-3.4.4.win-amd64-py2.7.exe - for Python 2.7, running on Windows 64-bit
I am trying to install some additional packages that do not come with Anaconda. All of these packages can be installed using pip install PackageName. However, when I type this command at the Anaconda Command Prompt, I get the following error:
Fatal error in launcher: Unable to create process using '"C:\Python27\python.exe
" "C:\python27\scripts\pip.exe" install MechanicalSoup'
I also tried to run the command from the python interpreter after import pip but that also did not work (I got a SyntaxError: invalid syntax).
I am a noob and understand that this might be a very basic question so thanks for your help in advance!
PS: I am using Windows 7, 64 bit, conda version: 3.7.1 and python version: 2.7.6.
When installing anaconda, you are asked if you want to include the installed python to your system PATH variable. Make sure you have it in your PATH. If everything is set up correct, you can run pip from your regular command prompt aswell.
Using #heinzchr's and #mmann's suggestions I was able to piece together the problem. I already had a version of Python 2.7 saved at C:\Python27 and I had to remove this from the Path (My Computer's properties> Advanced system settings> System variables> Path). I can now use pip install from the command line.
There is a way around the use of pip
From the anaconda terminal window you can run:
conda install PackageName
Because MechanicalSoup isn't in one of anaconda's package channels you will have to do a bit of editing
See instructions near the bottom on their blog
For those looking for Python packages not added to current channels in anaconda, try https://conda-forge.org/ For example, if you want to install MechanicalSoup you'll find it at https://anaconda.org/conda-forge/mechanicalsoup and use the -c option to tell conda the channel to use:
conda install -c conda-forge mechanicalsoup
