Thanks a lot
Sorry for my poor English. After some googling I found that in Pyqt 4.10 and above, pyqtconfig.py seems be removed. Please check http://pyqt.sourceforge.net/Docs/PyQt4/build_system.html#module-PyQt4.pyqtconfig
I added a pyqtconfig.py and sipconfig.py get from web.
After that Eric4 starts (with some errors). Haven't do many operations in the editor yet.

I have VM win7 x64, Python 3.6 and Im trying to install pyrfc SAP connector.
I have installed NWRFC library, set it in PATH variable, installed egg pyrfc-1.9.5-py3.5 with easy_install, and installed Visual c++ redistributable 2015 (x64) 14. But import always fails:

On same machine I have also Python2.7 - its using same NWRFC library and it works with no problem.

What could be the issue? Or how can I trace the import to know which other library is missing?
On github there are issues related to this, and some people solved it by:
One person reinstalled SAP SDK:
after some troubleshooting at least in my case was fixed after I re-downloaded the SAP SDK making sure I was downloading the Windows version.
Another person said:
If I uninstall pyrfc v2.0.1 and reinstall v1.9.93 using pyrfc-1.9.93-cp37-cp37m-win_amd64.whl, it works even without needing env var SAPNWRFC_HOME.
Try:
pip install pyrfc
It works for me.
I am having trouble installing Orange3 from github on openSUSE 13.1.
I have all requirements installed: gcc, g++, python 3-devel, pysci, pyqt4devel etc.
I followed these instructions, everything seems to work (with many warnings when compiling), however when entering in Orange.canvas, there are no widgets at all. It seems they have been missing on installation/compilation.
Any idea about what I did miss in the install or requirements?
Thanks for the -l3 options.
All the widgets get the same error on import
File "./Orange/widgets/utils/overlay.py", line 10, in <module>
import enum
ImportError: No module named 'enum'
Could not import 'orangecontrib.datafusion.widgets.owsamplematrix'``
I am not Python specialist, I will check for this module ..

Anybody can help me with this?
I think it is installing to the wrong location. Normally when you install Python packages, they get installed to C:\Python27\lib\site-packages. Somehow you installed wxPython to C:\Python27\ArcGISx6410.3\lib\site-packages. I would uninstall wxPython and when you re-run the wxPython installer, specify where to install it.
I should note that wxPython works fine for me on Windows 7 when it is installed in the correct location. I can import wx from both Python's interpreter and in PyScripter.
I am installing spark 1.2.1 on windows 8 and I have downloaded a prebuilt package for Hadoop 2.4
When i am running pyspark i am getting the following error:

I have searched and i got that in general the error is caused as the path variable are not correctly defined,but i have checked and my variable are all in place. How can i solve the error?
"The system cannot find the path specified." Which path is it talking about.?
In my case the problem came from the terminal I was using. On Git Bash on Windows I was getting the error : line 96: CMD: bad array subscript when executing spark-shell, but when I tried on PowerShell it worked fine.
The way I debugged this issue was to rem the "#echo off" command on all the command files that got called by pyspark.cmd.
In the end I nailed it down to me having JAVA_HOME set to "C:\ProgramData\Oracle\Java\javapath" which is wrong as one of the cmd scripts adds a "\bin" to JAVA_HOME before calling java.exe and it was triggering the "The system cannot find the path specified." error.
So I changed JAVA_HOME to "C:\Program Files\Java\jdk1.8.0_25" and it worked fine.
Now I have to un-rem the "#echo off"s. Hope it helps!
It maybe caused by cygwin in the DOS classpath. Spark uses the find command in the file 'spark-class2.cmd', which used then the cygwin find command instead of the DOS find command, which works somewhat different. I removed cygwin from the DOS PATH, which solved the problem.
I've been dabbling in biopython for about a year and I recently upgraded to Biopython release 1.59. I've been refreshing my skills with some tutorials but I always get the error below when I run a for loop and any module from the biopython library:
IndentationError: expected an indented block
I only get this error when I call the .py file written in Komodo Edit version 7.0.2 from the command line terminal:
Priyas-iMac:~ Priya$ python /Users/priya/Documents/Python/Tutorials/BioParse.py

IndentationError: expected an indented block
When I use the command line to call old .py files that I wrote a year ago as above they run fine. And when I start up python directly and type in the tutorial example line by line it works fine:

How can I fix my .py file so I can just run it from the terminal?
Any insight into this problem would be greatly appreciated!

It turns out that when I was originally learning python, I stupidly named a tutorial file "random.py" to practice making a random number generator. When biopython was importing other required modules, it kept pointing to that file instead of the random library module:
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/Bio/Nexus/Nexus.py", line 15, in <module>
import os,sys, math, random, copy
File "/Users/Priya/Documents/Python/Tutorials/random.py", line 27

Thanks for the help, everyone!
Check if all the files and modules imported have the same indentation (tabs or spaces and same number of spaces).
From the Style guide for Python code you can read:
Use 4 spaces per indentation level.
For really old code that you don't want to mess up, you can continue to use 8-space tabs.
And regarding tabs and spaces:
Never mix tabs and spaces.
The most popular way of indenting Python is with spaces only. The
second-most popular way is with tabs only. Code indented with a
mixture of tabs and spaces should be converted to using spaces
exclusively. When invoking the Python command line interpreter with
the -t option, it issues warnings about code that illegally mixes tabs
and spaces. When using -tt these warnings become errors. These options
are highly recommended!
For new projects, spaces-only are strongly recommended over tabs. Most
editors have features that make this easy to do.
Maybe Komodo is changing something automatically (some editors do). Try to edit the file in a more plain editor and look for the tabs. You may have an option to show you the spaces and tabs as visible.
Hope it helps!
