I used easy install with Python 2.7 and now try to update to Python 3.4 but the pip is not very clear.
My OS is Windows 7 - 64Bits and I do not have administrator rights. For the moment I enter in a terminal:
C:\Users\bc50414\Documents>pip install Pyside
Fatal error in launcher: Unable to create process using '""C:\Program Files (x86)\Python34\python.exe"" "C:\PF86\Python34\Scripts\pip.exe" install Pyside'
Where pip is just an alias for doskey pip=C:\PF86\Python34\Scripts\pip.exe $*. Apparently there is a problem with spaces, so using this solution (python3=C:\PF86\Python34\python.exe $*):
C:\Users\bc50414\Documents>python3 -m pip install Pyside

PIP should already be included with Python 3.x
Open a command prompt in windows.
and type pip
you can open a command prompt by pressing windows button then type cmd in search for programs.
It should also be installed in accessories folder from your windows start button.

I have installed the latest version of IBM SPSS Statistics(Version 26) which has pre installed python 3.4 and 2.7. i am trying to use version 3.4 python. i am able to import modules like pip , sys , os etc. i tried pandas the same way. i am unable to do so. getting error no module found. Hence going through our forum and IBM support did the following changes.
received the following error
1) tried pointing the site-packages via
import sys
# Assuming windows and standard python folder here.
sys.path.append(r"D:\Python34\Lib\site-packages")
2) changed the path in the settings of SPSS
3) Tried installing pip in the below folder as suggested in the forum but got message i have already installed the updated version.
C:\Program Files\IBM\SPSS\Statistics\Subscription\Python3
4) following versions of python were installed
have tried what i could. Need your expertise help to fix the same which will help me to install/use modules needed for SPSS. Thanks.
This is going to be painful to explain, I'll do my best.
As far as I can tell, you're on windows. Usually when we need a new package, we just open cmd and type pip install xxx (assume you added python to path when installing it). The reason that this works, is because when you type pip install xxx in cmd, windows recognize pip to be a command because python path is in system variables. Windows know that I can execute pip install with this python path.
However for SPSS python (3.4), that python had a different path in the system. Thus when you only have the 3.7 or 3.8 python in path, windows cannot install package to you 3.4 python, and I'm not sure if you can have more than one python path in system.
In order to fix this, you need to first figure out what's the path to your 3.4 python, then in this page you can follow the instruction to remove your 3.7 or 3.8 python in path, and add your 3.4 path, then you can do pip install xxxx for whatever package you want
I did the same thing with a arcgis python distribution, hope this works for you. If the attached page does not work, just google add python path to windows and look for a instruction that works on you PC
Oh and the reason that you can import pip, sys and some other package but not pandas, is because python is 'battery included', it comes with tons of packages pre-installed for additional functionality, but pandas is not one of them.
Fixed it since my ananconda had version 3.7 .i created virtual environment and installed 2.7 python with anaconda package. Pointed SPSS to the 2.7 folder and was able to import pandas.
Im trying to install curses for windows python 3.x with pycharm. i installed windows curses via pip. but if i import it, theres just message saying no module found.
In terminal/cmd
python -m pip install windows-curses
Requirement already satisfied
then if i type...
c:/.../.../python
import curses
curses.initscr()
i get a blank screen
but importing in python console or as script is not possible. no module found.
Any advises to globaly use import and not just in terminal/cmd.
Thanks
Open Pycharm>Settings>Project Interpreter. Click on the plus icon at the top right.In search type curses or any library which you want to install. Don't forget to check the 'Install to user's site package directory' box.
I am using Anaconda with python 3.4 and I am not able to get all the pillow packages I need I am afraid on Windows 8.1.
I installed pillow via the Anaconda console with:
pip install pillow
which lead to:
The following packages will be UPDATED:
conda: 3.10.0-py34_0 --> 3.10.1-py34_0
conda-env: 2.1.3-py34_0 --> 2.1.4-py34_0
pillow: 2.7.0-py34_0 --> 2.8.1-py34_0
pip: 6.0.8-py34_0 --> 6.1.1-py34_0
setuptools: 14.3-py34_0 --> 15.0-py34_0
Now, in the spyder IPython console I start with: import tkinter, from PIL import ImageTk I have no errors here, but when executing ImageTk.PhotoImage(file='a.jpg') I receive an error, telling me: ImportError: cannot import name '_imagingtk'
What did I miss?
I know this is not a complete answer, but I have had the same problem and spent a day trying to figure it out...
Here is a small subset of things I tried yesterday to the best of my weak memory...
-Tried upgrating to the latest Python environment using anaconda (tip: you can create one using
conda update conda
conda update anaconda
(I think that's it, but may have tried to make sure for key packages explicitly etc.)
-Tried using Python 3.3 environment using anaconda (tip: you can create one using
conda update conda
conda create -n py33 python=3.3 anaconda
activate py33
-Tried using PythonWin instead of anaconda (that one took some time, had to install packets like numpy manually...)
-Tried updating / downgrading / installing/ uninstalling all kinds of different variations of Pillow, PIL, etc....
-Tried using opencv instead of PIL, though did not try to write my own components...
-Tried manually copying Tcl/tk and a few others to the lib directory as suggested by some posts
-Tried using import tkinter instead of Tkinter, using import Image vs. form PIL import Image (and in general taking Image from PIL, or opencv, or Tkinter) and a lot of other similar changes to the point it fell I was doing silly things
-...
At the end, I googled a few pages about GUIs in python, and now I am using wx... I had to run
conda install wxpython
and that was it. I have to say that after all this, I am presently surprised by how easy it was to make it work, here is a code example...
You need tcl/tk library.
Install them using apt-get
Do sudo apt-get install tk8.6-dev tcl8.6-dev
--Reference.
I am trying to install NumPy from a wheel (.whl) file. I get the error:
numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform.
Details:
Windows 8.1 pro x64, elevated command prompt
Python 3.4.2
Package NumPy from Gohlke's site
File numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl copied in the pip.exe folder
The log file shows:
d:\Program Files\WinPython-64bit-3.4.2.4\python-3.4.2.amd64\Scripts\pip run on 01/23/15 11:55:21
numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform.
Exception information:
Traceback (most recent call last):
File "D:\Python34\lib\site-packages\pip\basecommand.py", line 122, in main

raise UnsupportedWheel("%s is not a supported wheel on this platform." % wheel.filename)
pip.exceptions.UnsupportedWheel: numpy-1.9.1%2Bmkl-cp34-none-win_amd64.whl is not a supported wheel on this platform.
What is wrong?
Short answer: rename the file to numpy-1.9.1%2Bmkl-cp34-none-win32.whl to install it.
You can check what tags your pip tool accepts for installation by running:
import pip; print(pip.pep425tags.get_supported())
In this case pip is incorrectly detecting your operating system to be 32-bits and the file you're trying to install was win_amd64 in its filename.
If you rename the file to numpy-1.9.1%2Bmkl-cp34-none-win32.whl (which now contains the tags that are considered supported) then you can install the package. It's a trick because the file is still built for 64-bits but this allows you to install the package as intended.
After several tests I think the problem is "win32" or "amd64" itself. I tried replacing those two with "any" and it worked.
In my case, the workaround to install gohlke packages on Python (3.4.4 (AMD64)) was to change the "cp34m" part rather than the "win*" parts in previous answers:
python -c "import pip; print(pip.pep425tags.get_supported())":
[('cp34', 'none', 'win_amd64'), ('py3', 'none', 'win_amd64'),
('cp34', 'none', 'any'), ...
ls -ld *:
matplotlib-2.0.0b3-cp34-cp34m-win_amd64.whl
numpy-1.11.1+mkl-cp34-cp34m-win_amd64.whl
pandas-0.18.1-cp34-cp34m-win_amd64.whl
Change the above names to:
matplotlib-2.0.0b3-cp34-none-win_amd64.whl
numpy-1.11.1+mkl-cp34-none-win_amd64.whl
pandas-0.18.1-cp34-none-win_amd64.whl
For example, pip install matplotlib-2.0.0b3-cp34-none-win_amd64.whl
Processing ...
...Successfully installed matplotlib-2.0.0b3
To add to the list of other possible solutions, I had to upgrade pip itself. The latest binary from Gholke's site had the "cp27m" tag, which didn't show up when I checked the pip tags using:
import pip; print(pip.pep425tags.get_supported())
After I upgraded pip, the wheel didn't work, but just doing a regular pip install numpy worked.
If you have, say, Python 3.4 installed, make sure to install the -cp34- version of the wheel and not -cp35-.
The current WinPython package manager need a two-characters fix to accept to recognize the new NumPy + mkl 'wheel'.

As a workaround, uninstall the NumPy package:
pip uninstall numpy
Then install it again from cache:
pip install numpy
I had the same problem with several packages after upgrading from 3.4.1 to 3.4.2.
Navigate to the directory where your 'pip.py' sits and then type following on the Windows command line:
..\python.exe pip.py install name_of_package.whl
This should work.
I had the same problem and tried to work it out with the suggested solutions.
I changed win64 to win32 and it didn't work either. But then I changed the name to original and this time it worked! The only extra thing I did was to go offline. That's so strange.
This has nothing to do with your operating system. Uninstall Python 32-bit and install Python 64-bit rather or alternatively find a 32-bit wheel file.
I have tried many ways of installing psycopg2 after having installed PostgreSQL using the one-click installer, but anyway I try confronts me with the same import error in python: ImportError: dlopen(/Library/Python/2.5/site-packages/psycopg2/_psycopg.so, 2): Library not loaded: libpq.5.dylib
Referenced from: /Library/Python/2.5/site-packages/psycopg2/_psycopg.so
Reason: image not found
I am on Mac OS X 10.5.8. I am using Python 2.5. I installed PostgreSQL from the installer (I did not port it) and it installed in /Library). I added /Library/PostgreSQL/9.1/bin to the setup.cfg of the source psycopg2, as instructed in the INSTALL file and everywhere on the internet and then ran sudo python setup.py build and then sudo python setup.py install.
I also tried exporting /Library/PostgreSQL/9.1/bin to my path instead and running sudo pip install psycopg2. But the exact same problem occurred in all of these scenarii.
I would greatly appreciate some help with this.
Best
Marion
The problem is that at runtime the libpq.5.dylib file can't be found because it is not in one of the default locations searched by the dynamic (runtime) linker. Try to define the environment variable DYLD_LIBRARY_PATH before launching python. I am no MacOS X expert but something like:
export DYLD_LIBRARY_PATH=/Library/PostgreSQL/9.1/lib
will probably work.
