opencv python : install in rapberry and failed to find a specific file

i tried to install opencv-python in my raspberry. i tried in many ways, including :
pip install opencv-python
but the process take so much time. (almost 2 hours untill now)
so i tried another way, which is installing from it's tar.gz file. i downloaded the tar.gz file, unarchive that, and run this command :
python setup.py install
with the result is error after 4 hours waiting. the error messages is :
Traceback (most recent call last):
File "setup.py", line 449, in <module>

File "setup.py", line 249, in main

can you guys help me? i tried many things before this problem happen. but now, i really stuck, no thing in the internet can help me

'Module' has no attritube 'Treestyle'

If found some hits on stackoverflow where people have issues using ete3 tools when PyQT4 is not installed, and this (used to) also apply for me. However, I've now tried to reinstall a piece of software and it keeps complaining about 'Module' has no attritube 'Treestyle'.
To test whether PyQT was installed, I ran this python script:
from PyQt4.Qt import PYQT_VERSION_STR
print("PyQt version:", PYQT_VERSION_STR)
Which prints:
('PyQt version:', '4.12.1')
I get this (common) error:

Note: this time arround I am trying to install it on Ubuntu for Windows, but up till now almost everything that ran on Linux ran on this one too. It might be relevent though.
Any ideas?
PS To reproduce the problem, follow the following steps:
$ sudo apt-get install python-qt4
$ virtualenv ~/mypy --system-site-packages
$ source ~/mypy/bin/activate
$ (mypy) > pip install VirtualMicrobes
$ (mypy) > virtualmicrobes evo --name TestMicrobes >> error
PPS User eyllanesc confirmed this is an 'Ubuntu for Windows' problem. I'm still trying to fix it though, if anyone can help me figure out how to link the pyqt4 packages correctly to my virtualenv that would be great. I've tried linken the native one with ln -s but I'm not getting any further

I had similar issues. The problem might be that you don't have all the depencies installed and ete3 is not telling you all of them.
You can see which dependencies are missing with this code:
import ete3
ete3.__file__
Run it and it will tell you which dependencies are missing. Note that you might need to run it multiple times before you install them all!

Installing pip for arcpy

I'm attempting to install pip for arcpy (arcgis 10.2 on windows 7). Running get-pip.py results in the following error message:
X:\python>python get-pip.py

sre_constants.error: nothing to repeat
Using an administrator command prompt doesn't help. My real goal is to get win32com working under arcpy. I usual just copy the appropriate directories out of c:\python27\lib\site-packages to c:\python27\arcgis10.2\lib\site-packages to install a package under arcpy (why doesn't arcpy come with pip?) but that's not working for win32com, presumably do to a missing dll or other windows specific file.

I would recommend the following:
Get the setuptools module
Get the pip module`
And then run the following in command line (assuming windows)
path-to-python path-to-setuptools install
path-to-python path-to-pip install
I work on a closed network (away from the interwebs of old) and cannot use get-pip.py so I find it best to simply download the actual modules and hard install.
Keep us posted!

Copy get_pip.py to "C:\Python27\ArcGIS10.2", then perform command "python get-pip.py" in the directory.
Note that keep network connected in the process, so that auto-download and setup setuptools,wheels,etc.
Hope that can help you.

Try opening a CMD prompt and typing:
C:\Python27\ArcGIS10.2\python.exe -m pip install -U pip

Getting “pika.exceptions.ConnectionClosed” error while using rabbitmq in python

I am trying to use rabbitmq in python.
My code is:
import pika
if __name__ == '__main__':
connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
I am running this file using:
python3 test.py
Error Signature:

Already referred this , but i dont have any sleep in my code.
Not really sure what could go wrong.
Please let me know if I am missing something obvious.

The issue was with rabbitmqctl. Reconfigured it, Restarted service, and the issue is fixed.
Make sure rabbitmqctl is installed(if installed, uninstall it and re-install;when you just enter rabbitmqctl, it should display the help)
rabbitmqctl start_app
TIP: I tried installing first using 'brew',but for some reason, I was not able to get it right. So installed, rabbitmqctl as a separate package and added to PATH

getting DistributionNotFound error, but package exists

I am running pyjade for Django templates as I find it much easier to write in, but I am trying to convert it to html with the built in converter. When I run pyjade -c django input.jade output.html I get the error pkg_resources.DistributionNotFound: six. However, the package six does in fact exist, and I can import it on python, and when I run pip install six --upgrade it says it is already up-to-date.
Here is the full traceback:
Traceback (most recent call last):
File "/usr/local/bin/pyjade", line 5, in <module>
from pkg_resources import load_entry_point
File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2707, in <module>

needed = self.resolve(parse_requirements(requirements))
File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 584, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: six
What would be causing this error?

Re-install via easy_setup (vs pip) solved it for me on OS X Mavericks:
sudo easy_install six
Hope that helps you!

An old setuptools was my culprit.
pip install -U setuptools
