I have recently installed SimpleCV on Windows 10 from the superpack. Everything went well during the installation, and I was able to successfully run the first example problem in "Practical Computer Vision with SimpleCV" (good book, btw) from within IDLE. Here's the code:
from SimpleCV import Camera, Display, Image
cam = Camera()
display = Display()
img = cam.getImage()
img.save(display)
Simple enough, and it worked fine. Where I ran into problems was when I tried to start up the SimpleCV console. First of all, no link was created on the Windows desktop, and there was nothing for SimpleCV on the Start menu. So, I tried the other methods listed in the book. First, from the console, I tried to run it as a Python module:
C:\User> python -m SimpleCV.init
And what I got back was:
ERROR:
Traceback (most recent call last):

raise(e)
ImportError: No module named IPython
Next, I tried the listed alternative: just starting python and importing and executing the Shell. Entering:
>>> from SimpleCV import Shell
resulted in the same error as above.
I also tried installing ipython by running pip. But, it looks like pip didn't get installed either.
So, what environmental variable did the installation program not set correctly? Just so you know, I posted this same question on the SimpleCV site, but have not received a response as of yet.

Chipping away at this. Read the banner on setuputils install. Ran Python27\Scripts\easy_install.exe. Can now call pip. However, entering this at the command line:
C:\Users> pip install ipython
gives this error:
C:\Python27\lib\site--packages\pip-7.1.2-py2.7.egg\pip\_vendor\requests\packages\urllib3\util\ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cuase certain SSL connections to fail. For more information, see...
So, I'm making progress. Any suggestions?
Have you tried to install ipython from source code?
$ tar -xzf ipython.tar.gz
$ cd ipython
$ python setup.py install
See https://ipython.org/ipython-doc/3/install/install.html
There are a lot of requirements more. I recommend the SimpleCV's github repository instructions https://github.com/sightmachine/SimpleCV#windows-8

I am relatively new to Linux/Ubuntu (so please take it easy on me) and I am trying to install Autokey to use the text expansion functionality. I have tried installing it from the instructions on the Github page here - https://github.com/autokey/autokey#installation
However, no matter whether I follow the installation process under the Ubuntu/Mint/Debian section or the instructions to install via pip I cannot seem to get the program working.
The installation seems to be successful (running a 'which' command gives the path installed) but clicking on the icon does not launch the program.
I have also tried to install directly from Ubuntu/GNOME software manager but that also will not launch the program once installed.
I have tried installing both the GTK and QT frontends and neither will launch. I don't get an error message or anything. I have opened up the System Monitor to see if a process even appears (however briefly) and there's nothing.
Typing autokey-gtk into Terminal gives:
/usr/local/lib/python2.7/dist-packages/autokey/gtkapp.py:24: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.

Can anyone please help? Thank you.
I am a newbie too and installed Autokey 0.90.4, which did not work for me either. Someone suggested I try 0.95.1 because the other version is 7 years old.
I installed the new version with some acrobatics from the Autokey Github page, using the PIP method. At 1st it did not work, but after doing import setuptools it did. That might be a coincidence since it was after installation of the Ak package itself.
I know this sounds convoluted, but I am not familiar (yet?) with Linux. Anyway 0.95 works for me.
install module python-xlib and it will work, like this:
On Deb:
apt install python3-xlib
You might later need python autokey module as well:
pip install autokey
I'm trying to follow/modify these instructions to get matplotlib compiled on pypy3, but when I try to compile wxpython-cffi with pypy3 build.py dox I get this error:
Traceback (most recent call last):

File "build.py", line 422, in __init__
os.chdir(newDir)
FileNotFoundError: [Errno 2] No such file or directory: '/Users/user/tmp/docs/doxygen'
The steps I followed are:
installing pypy3 with brew: brew install pypy3
trying to install matplotlib with pip_pypy3 but getting this long error message
trying to install wxpython with pip_pypy3 install wxpython and getting another very long error message
Download wxpython-cffi: hg clone https://bitbucket.org/amauryfa/wxpython-cffi
installing wxWidgets with brew: brew install wxWidgets
which doxygen --> /usr/local/bin/doxygen
export DOXYGEN=/usr/local/bin/doxygen
and finally pypy3 build.py dox which results the error above
changing the line 657 of build.py from pwd = pushDir(posixjoin(wxDir(), 'docs/doxygen')) to pwd = pushDir('/usr/local/bin') results in a completely different error:
Running command: dox
./regen.sh xml
/bin/sh: ./regen.sh: No such file or directory
Command './regen.sh xml' failed with exit code 127.
I would appreciate if you could help me know what is the problem and how I can solve it. the final goal is to get the matplotlib installed on pypy3, so out of the box solutions also would do.
P.S. I'm not sure if my tags are appropriate. I would appreciate if the moderators could let me know if they need to be modified/removed
Matplotlib and PyPy is a known pain point on OSX, we have had multiple reporters but since the PyPy team does not have an OSX developer we cannot fix it on our own. See https://bitbucket.org/pypy/pypy/issues/2327 or any of the other matplotlib issues on the PyPy issue tracker.
It would be great if someone capable of working through this with us would step up and help us fix it, reach out with a response to any of the multiple issues or on IRC at #pypy
I have some difficulties trying to install Scipy for Python 3.5 on a Windows 10 machine and I hope I can find some help here. So here is what I have done so far.
I have downloaded the numpy+mkl for python 3.5 and 64bit version as well as the scipy0.18.1 for the same versions, from Gohlke's website
I installed the numpy+mkl whl with:
python -m pip install numpy-1.11.2+mkl-cp35-cp35m-win_amd64.whl
all goes well.
then I install the scipy package the same way like:
python -m pip install scipy-0.18.1-cp35-cp35m-win_amd64.whl
This also completes.
However, when I try to run python afterwards I get the following error:
Fatal Python error: Py_Initialize: can't initialize sys standard streams
Traceback (most recent call last):
File "C:\Python35\Lib\site-packages\scipy\io\__init__.py" , line 97, in <module>
File "C:\Python35\Lib\site-packages\scipy\io\matlab\__init__.py", line 13 in <module>
File "C:\Python35\Lib\site-packages\scipy\io\matlab\mio.py", line 8 in <module>
ImportError: No module named 'numpy'
I also get a pop-up that Python has stopped working.
I have tried a different order in which I installed the packages, but all lead to the error mentioned when Scipy is installed.
I also installed did this on a windows 7 machine and there it works.
Does anybody have any idea what causes this issue?
I also had some issues. So I just installed Anaconda3 insted of python directly.
I used to install python (2.7.6) packages using sudo pip install [...] until I recently decided that this was a bad idea and I should use: pip install --user [...] instead.
Since I am using Mac OS X (10.10.3), my python modules had been installed into /Library/Python/2.7/site-packages. Now, with the --user option enabled, they are being installed into: /Users/USER/Library/Python/2.7/lib/python/site-packages
I have since moved all packages (including pip/setuptools) into this destination, adjusted my $PYTHONPATH and changed the file ownership to my local user. I expected that I would now be able to call pip install --user [..] and everything should go smoothly.
Unfortunately, this is not the case. For any pip install (or pip install --upgrade) command I receive the same error (below). The same is true when using a virtualenv - the same error shows up and I have no clue why.
However, everything does work "fine", when I use sudo pip install --user, which is why I assume that it is somehow related to a file-permission error I can not see. (It's not exactly fine, as the newly installed package will be in the right location, but all files are owned by root.)
Any idea what I am doing wrong or how to debug this?
pip install --upgrade --user tornado

I also checked the location of pkg_resources and deleted pkg_resources.pyc, which is located in /usr/local/lib/python2.7/site-packages for some reason, but it didn't change anything. (My local user also has full access rights in this location.)
[UPDATE:]
For some reason I was able to install virtualenv without root (pip install --user virtualenv), but all other packages I tried still fail. Also, if I switch to a new virtual environment, I still receive the same error. I am now thinking this is related to my $PYTHONPATH variable, which appears to not be updated for my virtualenv, but I haven't found the real solution, yet.
Alright, so I found the actual problem and solution. My $PYTHONPATH contained an invalid directory. I setup my $PYTHONPATH a long time ago and wrote it into a .bashrc (or more accurately .bash_profile) script.
pip was probably looking through all directories in $PYTHONPATH, although I don't know what it is doing in each of them that causes the above error, but removing the invalid directory fixed my problems.
I also now highly recommend to just use virtualenv instead of a static setup.
I am new to python but have been using both IDLE and EricIDE for a few weeks without any major problems.
I was editing a program I had written that called random.randint() function and it wouldn't work.
Previously, this program had been working and I had not changed that call out.
I then loaded another program that uses the same function that had been working and it would not run either.
I tried to load the program in IDLE but IDLE wouldn't load. After trying several reboots and reloads EricIDE wouldn't load either. I noticed a black window popping up and disappearing quickly when I try to launch either IDE from my previously working desktop shortcuts.
Searching for help led me to run python shell from the windows command line by going to C:\python33\ and typing "python" to run python shell, I get:
File "C:\python33\lib\sre_constants.py", line 18, in (module)
from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT
I am using Windows 8 (new to it as well and still trying to figure it out).
At this point I'm assuming my problem is with my python installation since the python shell won't work. I have uninstalled and reinstalled Python 3.3.1 but the problem persists. I also deleted the .idlerc folder from my Users directory as suggested in another thread that was similar to my problem but that doesn't seem to have helped either.
Thank you for any help you can provide.

I suggest you uninstall. Completely remove C:\Python33 and also C:\Windows\System32\python33.dll. _sre is built in to the latter DLL. MAXREPEAT is set by its initialization functionPyInit__sre (Modules/_sre.c). Clearly, something is wrong there.
When you download the 3.3.1 installer, make sure you get the right binary for your platform, i.e. x86 for 32-bit Windows and X86-64 for 64-bit Windows.
