My knowledge of Python is still pretty basic, and I am only now trying to wrap my head around how to use / call libraries from within Maya. (Because I need to create a basic UI from QT Designer and have it be opened in Maya after converting it to a .py file)
After I learned to properly convert a .ui to a .py, I now get this error in Maya
"Module use of python34.dll conflicts with this version of Python"
I tried following what was said here and here, but even then - after setting these environment variables...
PYTHONHOME = C:\Program Files\Autodesk\Maya2016\bin\maya.exe
PYTHONPATH = C:\Python34
... I a still unable to run a basic .py file. In fact - as long as the PYTHONHOME variable is in effect, Python from within Maya no longer does anything.
This code below is the resulting python file that I got from converting the .ui file that I saved out of QT Designer.
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'test.ui'
#
# Created by: PyQt5 UI code generator 5.4.1

from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Dialog(object):
def setupUi(self, Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(400, 300)
self.buttonBox = QtWidgets.QDialogButtonBox(Dialog)
self.buttonBox.setGeometry(QtCore.QRect(30, 240, 341, 32))
self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
self.buttonBox.setStandardButtons(QtWidgets.QDialogButtonBox.Cancel|QtWidgets.QDialogButtonBox.Ok)
self.buttonBox.setObjectName("buttonBox")
self.retranslateUi(Dialog)
self.buttonBox.accepted.connect(Dialog.accept)
self.buttonBox.rejected.connect(Dialog.reject)
QtCore.QMetaObject.connectSlotsByName(Dialog)
def retranslateUi(self, Dialog):
_translate = QtCore.QCoreApplication.translate
Dialog.setWindowTitle(_translate("Dialog", "Dialog"))
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
Dialog = QtWidgets.QDialog()
ui = Ui_Dialog()
ui.setupUi(Dialog)
Dialog.show()
sys.exit(app.exec_())
I've come across some different online notes that advised the use of PySide, and after trying to use:
from PySide.QtCore import *
from PySide.QtGui import *
I still couldn't test if this works, because apparently QtWidgets isn't a module?
I'm pretty lost. The bigger picture is that I just want to be able to run a ui created from QT Designer from Maya's script editor. I have no idea where to begin with learning about libraries. Would anyone here be kind enough to give some advice?
Additional info:
I am using Maya 2016, running on a Windows 10 64 bit OS.
I also have a Python 2.7 in my C: drive
And I am using PyQt5-5.4.1-gpl-Py3.4-Qt5.4.1-x64
Thank you for your time.
Maya's python interpreter is in the 2.7 series (or 2.6 for Maya 2013 and earlier). Your PYTHONPATH is pointing at a python 3.4 install. You also want to make sure that if your Python 3.4 is in PATH it comes later than the maya python install location. This is all to makes sure that Maya doesn't get confused and try to run python 3 code or dlls which it cannot handle.
Also, maya 2016 is running on PyQT4. Maya 2017 runs on PyQT5. So you'll probably want to use a PyQT4 version of designer

Working on Automate The Boring Stuff project and having trouble with pyperclip and IDLE. pyperclip is successfully downloaded and works fine in Terminal but when I import pyperclip in IDLE, I get the below error.
UPDATE - This is happening with other modules - anything I've installed in the terminal aren't importing into IDLE.
import pyperclip
Traceback (most recent call last):
File "", line 1, in
import pyperclip
ModuleNotFoundError: No module named 'pyperclip'
I figure I have the module saved in the wrong folder somehow. Below are the sys.path outputs from my Terminal and IDLE.
In terminal:
'/anaconda/bin',
'//anaconda/lib/python36.zip',
'//anaconda/lib/python3.6',
'//anaconda/lib/python3.6/lib-dynload',
'//anaconda/lib/python3.6/site-packages',
'//anaconda/lib/python3.6/site-packages/Sphinx-1.5.1-py3.6.egg',
'//anaconda/lib/python3.6/site-packages/aeosa',
'//anaconda/lib/python3.6/site-packages/IPython/extensions',
'/Users/andrewricardo/.ipython']
In IDLE:
sys.path
['', '/Users/andrewricardo/Documents', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python36.zip', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages']
There are multiple paths here - how do I effectively move the pyperclip module to the correct place?
OR - Is there something else going on here?
Each python installation and uses its own .../lib/site-packages for 3rd party modules, and you have two. If you ran the non-anaconda python in the terminal, the same that is running IDLE, it would have the same problem. Indeed, that python is the source of the ImportErrors.
Option 1: Separately install all packages you want to use with the non-anaconda python (and IDLE) in its own site-package directory. In IDLE Shell, get the path to its executable
>>> import sys; sys.executable
Save are remember the resulting 'python-path'. Then in the terminal, run
python-path -m pip install package-name
for each package.
Option 2 (uses a little known feature of site-package directories): in
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages
add a file name, for instance, anaconda.pth, containing one line.
//anaconda/lib/python3.6/site-packages
(I have no idea why the double / or if it is really needed; I just copied it from your question.) This makes the anaconda python site-packages an extension of the framework python site-packages. Since both are for 3.6, one copy should work for both.
Had this same issue and googled
'why is importing pyperclip in my python file giving an "modulenotfounderror"but working fine in the idle'
and this page came up. then i also checked this [installed Pyperclip, trouble importing to IDLE.
I am new to python, had the same issue using the same book after pip installing pyperclip here's what I did to solve this issue.
I copied the pyperclip-1.7.0-py3.7.egg-info and pyperclip folders from
C:\Users\USER\AppData\Local\Programs\Python\Python37\Lib\site-packages into the C:\Users\USER\Anaconda3\Lib\site-packages folders and C:\Users\USER\AppData\Local\Programs\Python\Python37 folders and it worked. Hope this helps. If it doesn't. Try this code in your text editor because that's what I did using Atom and how i was able to solve it.
import sys
print(sys.executable)
Then copy the pyperclip-1.7.0-py3.7.egg-info and pyperclip folders into the path that the above code gives you.
I'm using python 2.7 installed via macports, pyobjc, cocoa and notably scipy (via FlowCytometryTools) with py2app to create a small mac application. Py2app's setup.py run with sudo python setup.py py2app completes nicely with -A for testing, but is unable to complete when running without that parameter to create a full .app build.
The build process will get a variable distance through the unconditional imports and then give error: [Errno 35] Resource temporarily unavailable and immediately exit. The number of unconditional import lines that complete before the error occurs changes. The longest run so far was seen when running immediately after a reboot. I've tried running with and without removing the previous build/dist folders to no effect.
Modules not found (unconditional imports):
...
* builtins.int (Cython.Build.Inline, Cython.Compiler.ExprNodes, IPython.utils._tokenizeerror: [Errno 35] Resource temporarily unavailable
My setup.py looks like this:
import sys
sys.setrecursionlimit(1500) #required to avoid recursion triggered early exit in py2app while compiling scipy. (default is 1000)
from setuptools import setup
APP = ['FlowMac.py']
DATA_FILES = ['FlowMac_Main.xib']
OPTIONS = {'argv_emulation': True}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
and the imports section of my python file FlowMac.py looks like this:
from Cocoa import *
from Foundation import *
from AppKit import *
from FlowCytometryTools import * #file/data handling via scipy and pandas
from pylab import * #graphing histograms
Commenting out both the FlowCytometryTools and the pylab imports allows the py2app build to complete but of course renders the program nonfunctional.
What is happening?
How can I get more information on which resource is unavailable?
was hitting a recursion limit a clue to my problem?
I'm running Yosemite on a MacBook Pro with 8GB RAM, so I'm very surprised to be hitting a wall here.
Thanks for your time.
UPDATE 4/29/2015:
Importing everything works fine if I remove my .xib from the datafiles array of the py2app launcher setup.py. A blank file with just import Cocoa, Foundation and Appkit works fine. Importing the xib with any one of FlowCytometryTools, pylab, scipy, matplotlib, numpy does not work. pylab and FlowCytometryTools rely on the other three, and any one of scipy, matplotlib or numpy brings in py2app recipies for the other two. One of these recipies isn't working with the xib, but I don't know why...
No experience with py2app, but I am wondering if you tried generating a more minimal version of the code that would fail to aid troubleshooting?
Maybe having FlowMac.py include nothing but the import statements:
import Cocoa
import Foundation
import AppKit
import FlowCytometryTools
import pylab
Also could you narrow it down to whether the problem appears due to pylab or due to FlowCytometryTools? (By commenting them out individually?)
From my testing, this error seems to be caused by the log output itself from py2app. Try redirecting standard error to a file:
python setup.py py2app 2>error_log
This should work around the error.
Using python 2.6 on my mac the following works fine (i.e. a plot window opens):
import matplotlib.pyplot as plt
from numpy import linspace, sin, pi
plt.ion()
print "Is interactive:?", plt.isinteractive()
x = linspace(-pi, pi, 1001)
plt.plot(x, sin(x))
raw_input() #keep the window open
It works when I run it in shell (i.e. $ python test.py) as well as when I run it in an interactive python terminal.
I recently installed python 2.7 and with it nothing happens (more precisely, plot window appears in Dock, but doesn't open) when I run my script from shell. The value of plt.isinteractive() is false even after plt.ion().
When I run the same code in an interactive python terminal, everything is fine.
The answer to this question makes the plot window appear, but I find it annoying that now I have to add plt.pause(0.1) to my script.
Is there a way to get the earlier behaviour without modifying the code?
The backend is macosx.
It seems that this is a bug related to matplotlib 1.4. An ugly workaround is to include:
import sys
sys.ps1 = 'SOMETHING'
before importing matplotlib.
Alternatively, one can use ipython to run the script.
For more details see here https://github.com/matplotlib/matplotlib/issues/3505
I've been animating evolution of surfaces (stored as 3d numpy arrays) using matplotlib, but this method is slow and clunky. I gather that VPython and MayaVi are better alternatives, but apparently neither is available yet in Python 3.4 (which is what I'm using). Are there any good ways to perform 3d animation in Python 3.4?
You can get the vpython working in python3.4 now. Follow this steps:
Preparation
Download the four packages TTFQuery, FontTools, and Polygon ,vpython in get the requisites packages to same directory.
Installation
Run cmd
cd path/to/package_downloaded_directory
pip install packagename.whl
Find the file C:\Python34\lib\site-packages\vis\materials.py
Open the file in an editor, then go to line 70
Comment the two lines just like this
class raw_texture(cvisual.texture):
def __init__(self, **kwargs):
cvisual.texture.__init__(self)
# for key, value in kwargs.items():
# self.__setattr__(key, value)
Save the changes
Note that when when you use vpython to code a script, the first line must be like below:
from vis import *
Below is my code sample
from vis import *
sphere(pos=vector(0,0,0),radius=0.5,color=color.red)
arrow(pos=vector(0.5,0,0),axis=vector(1,0,0),color=color.green)
I am having a problem with tkinter.ttk on mac. I am using macports and python3.1. When I try to use tkinter.ttk I get very old looking gui elements.
eg: I get this
Instead of this:
The code I used is:
from tkinter import *
from tkinter import ttk
root = Tk()
button = ttk.Button(root, text="Hello World").grid()
root.mainloop()
I would be happy to provide any information from my computer needed to answer this question. As I am a novice programer please tell me where to find said information.
I have a Macbook 5,2 with Snow Leopard installed. Any help would be appreciated.
Thanks, Marlen
Question Update:
I installed tk #8.5.9_0+quartz as schlenk suggested only to get this error:
TclMacOSXNotifierAddRunLoopMode: Tcl not built with CoreFoundation support Abort trap
I fixed this error with the patch from https://trac.macports.org/ticket/22954. I followed the instructions to the letter(they are):
$ cd /opt/local/var/macports/sources/rsync.macports.org/release/ports/lang/tcl
$ sudo patch < ~/Downloads/tcl.2.patch
$ sudo port install tcl
This created a new error which is:
Traceback (most recent call last):
File "hello.py", line 5, in <module>

"uplevel #0 [list source $file]"
This probably means that tk wasn't installed properly.
The problem might be macports. There are three versions of Tk you could use as the basis for your ttk. The screenshot looks a lot like the older X11 Tk, not the aqua based Tk.
1. Tk via X11.
2. Tk compiled with Carbon 'windowingsystem -aqua'
3. Tk compiled with Cocoa
So you should try to either build a Tk variant 'quartz' via macports or you should get some prebuilt version (e.g. ActiveStates) that has the right version already built.
So try:
sudo port build tk #8.5.9+quartz
Have a look at tutorials here for some more guidance:
http://www.tkdocs.com/tutorial/install.html#installmac
try
style = ttk.Style()
print(style.theme_names())
style.theme_use('default') # change 'default' to something better
I haven't played with ttk, however I have a decent amount of experience with tkinter. I belive you have to fill out the style keyword argument.
I think it would look something like this.
from tkinter import *
from tkinter import ttk
root = Tk()
button = ttk.Button(root, text="Hello World", style="somestyle").grid()
root.mainloop()
