We Keep Coding

Is there a way to run Python code in Pydev?

I'm new to Jython and PyDev. I need to run my Python code in Eclipse.
The Python code works in Spyder/Jupyter Notebooks. When I run the programm as Jython Run/Python Run, an error pops up.
How can I solve this problem?

Looks like a similar issue was discussed here
How do I fix UnsupportedCharsetException in Eclipse Kepler/Luna with Jython/PyDev?
and adding
-Dpython.console.encoding=UTF-8
to the Run Configurations -> VM arguments could be a solution.

Tkinter in virtual environment (PyCharm/Mac OS 10.13.4)

I have set up a virtual environment and when I try to run matplotlib on it, I get the following error:
Traceback (most recent call last):

ImportError: No module named _tkinter
From what I understand, I need to
set the environment variables correctly in the activate script
or I can symlink tkinter folder to virtualenv python2.7.
I have followed the steps here: TKinter in a Virtualenv, but I am still getting the error.
Steps that I followed are:
To virtualenv/bin/activate, I added
TK_LIBRARY=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/site-packages/PIL:/usr/lib
TKPATH=/usr/lib/python2.7/lib-tk:/usr/lib/python2.7/site-packages/PIL:/usr/lib
TCL_LIBRARY=/usr/lib
export TCL_LIBRARY TK_LIBRARY TKPATH
In virtualenv/lib/python2.7 I ran, ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_tkinter.so
Note that when I am using the system Python as an interpreter on PyCharm, matplotlib works fine which gives me a feeling that Tkinter is available somewhere on my system but I am failing to call it from my virtual environment.
The link above seems to be working for Ubuntu. I am wondering if anyone know what is the analogous version for Mac.
Thanks!

If you are not specific to using tkinter in virtual environment then you can use the following lines of code:
import matplotlib
matplotlib.use(‘TkAgg’)
import matplotlib.pyplot as plt
I hope this solves the problem.

import error but in the program init, can someone help me? (Python 2.7.14)

I have those errors when i'm trying to import the matplotlib.
How can i fix this?
I have install matplotlib with the pip install matplotlib and this was a succes.
But when i import the package i have this kind of error.
i see it is in the init block but how can i fix this?
i have already tried the pip matplotlib upgrade but this keeps the same problem.
i just have matplotlib uninstalled and back installed and it is the same problem.
My code:

A "p" seems to be missing from "pyplot". You have pylot instead of pyplot in the import statement.

I have imported numpy , scipy , matplotlib and opencv.
The code getting executed on windows 7 machine but after upgrading to ubuntu 16.04, getting error like this.

Any help is appreciated.

matplotlib says it needs libpng15, but I have libpng16

The problem is likely a configuration issue, because getting the installation correct on Macs seems to be tricky. I'm running Mavericks and matplotlib 1.4.x, yet when I open a Python 2.7.5 shell and import pylib, I get this error:

I have libpng16 installed, but not libpng15.

I saw a hardcoded reference to libpng15 in _png.so.
Uninstall and install of matplotlib fixed the issue for me.

You can always moke it by generating a soft link like this
sudo ln -s /opt/X11/lib/libpng.dylib /usr/local/lib/libpng15.15.dylib
Not the cleaner solution but I haven't figure out why matplotlib stubbornly asks specifically for libpng15 and not any 15 or greater.
