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:
Python 3.6.0 (v3.6.0:41df79263a11, Dec 23 2016, 08:06:12) [MSC v.1900 64 bit (AMD64)] on win32

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 tried to install tensorflow after installing cuDNN, Cuda, bumblebee, nvidia driver etc., but after I rebooted, I couldn't get past the login screen. After a friend of mine fixed the problem, I still wanna use tensorflow with Python 2.7, how can I do so without messing up my system? I have cuda 9.1 installed.
Have you tried virtualenv to manage your pip packages? you can easily use it to avoid multi-version of tensorflow and Python,

I have Python2.7 on windows.
Installed scheduler as
$pip install apscheduler==2.1.2
pip Listing shows the scheduler2.1.2
But keep getting:

Every time I tried to run import matplotlib,
I have error ImportError: No module named Tkinter.

I tried to install the tk.x86_64 and tk-devel.x86_64 packages, and tried to reinstall the python package but the error still appeared.
Also I tried to import Tkinter but I got the following error.

Does anyone have a workaround for this error?
I'm using python2.7.12 on ubuntu16.04.
I installed it with this command:
sudo apt-get install python-tk
I tried to install tkinter package for python2.7.5 from the following link:
tkinter package
Also I found there is dependency library libTix.so()(64bit) for tkinter package and i got it from the following link: libTix.so()(64bit) package
after that i installed both then I could import Tkinter and import matplotlib.pyplot as plt with no errors.
My 2 cents. Open a terminal and type the following.
$ python

If you do not get an error like below then your Tkinter is fine and the problem is with matplotlib. Then try removing and reinstalling matplotlib.

ImportError: No module named tkinter
I was getting the error "ImportError: No module named '_tkinter'" for python3.5 in-spite of installing python3-tk and tkinter-dev.
It showed the error in following file:
File "/usr/local/lib/python3.5/tkinter/init.py", line 35, in
import _tkinter # If this fails your Python may not be configured for Tk
It got resolved for me by simply running the python from /usr/bin like /usr/bin/python3.5 from terminal!
In short, please ensure the python version being run from terminal has the tkinter installed and configured :)
My PC configuration: Ubuntu16.04 with default python2.7 and python3.5
I faced the same issue on a RHEL 7 machine. There was no python-tk package that could be installed. I found the solution here which solved the issue for me:
sudo yum install tkinter
This should work for RHEL machines using Python 2.
I have a 64-bit windows 7 OS where I installed ArcGIS with 64-bit Python 2.7.
I also installed 64 pyscripter editor.

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.
