I try to open the fibonacci template on my mac using Microsoft Excel from Parallels but I get the following error (xlwings version 0.4.1).
The file is well opened automatically with Microsoft Excel and the error comes.
Has someone any idea on how to correct that ?

If you want to use the Windows version of Excel from Mac through Parallels, you need to drive things from a Windows based Python installation, too (e.g. from the Windows Command Prompt instead of Mac Terminal).
If instead you want to drive Mac Excel 2011 or 2016 and in case Parallels is giving you a hard time, specify the path of the Mac Excel installation through app_target, see the docs or this question.

I am new to django. I wanted to create my first sample project so I followed all the usual ways(as in youtube) and installed python 3.4,pip,django etc. When the environment was set I typed the below command in windows powershell
django-admin startproject mysiteone
and got the below syntax error message(See last para)
My system uses Windows 7 OS. I was unable to find even the version of django i had installed. I dont know why.
I gave these codes in powershell:
django-admin startproject mysiteone
python -m django --version
Error message that I got as a result:

i had the same problem and i solved by migration to python >= 3.5 , it's an unpacking problem => https://www.python.org/dev/peps/pep-0448/
I'm trying to run this python code, but it keeps throwing the same error. I'm using pytesseract on a windows machine (coding in pycharm) to scan an image. I made a project on cloud9 that haevily used pytesseract in amazon web services and everything worked fine I am convinced that this is a windows problem. This is all in python 2.7 (this is a small test program I made to debug this same problem in a much bigger project)
Here's my code:
try:
import Image
except ImportError:
from PIL import Image
import pytesseract
filename = "Z:\Pycharm Projects\IBM-Waldon-master\screenshots\image.png"
print pytesseract.image_to_string(Image.open(filename))
I've tried making the meat of the code a function and restarting my computer but it still throws this error:
Z:\Python27\interpeter\Scripts\python.exe "Z:/Pycharm Projects/IBM-Waldon-
master/testest.py"
Traceback (most recent call last):

On Windows, PIL uses whatever program is registered to open a temporary .BMP file. When the program returns, the temporary file is deleted.
By far the most common problem is that the program sends back a return code even before it even opens the file, and the file is deleted before it can be opened. Unfortunately the default viewer in Windows Vista and 7 has this problem; XP used the Microsoft Image and Fax viewer which was OK.
You can use File Explorer to change the program associated with .BMP files.
I tried to read the text from the image using Pytesseract.I am getting Access denied message when I run the below script.
from PIL import Image
import pytesseract
import cv2
import os
filename=r'C:\Users\ychandra\Documents\teaching-text-structure-3-728.jpg'
pytesseract.pytesseract.tesseract_cmd = r'C:\Python27\Lib\site-packages\pytesseract'
image=cv2.imread(filename)
gray=cv2.cvtColor(image,cv2.COLOR_BGR2GRAY)
gray=cv2.threshold(gray,0,255,cv2.THRESH_BINARY|cv2.THRESH_OTSU)[1]
gray=cv2.medianBlur(gray,3)
filename='{}.png'.format(os.getpid())
cv2.imwrite(filename,gray)
text=pytesseract.image_to_string(Image.open(filename))
print text
cv2.imshow("image",image)
cv2.imshow("res",gray)
cv2.waitKey(0)
when I run the script I am getting below Error

Your code works except the setting of pytesseract.pytesseract.tesseract_cmd. The tesseract_cmd should set to the tesseract executable file installed in your machine.
Here is a sample usage of it.
pytesseract.pytesseract.tesseract_cmd = "C:/Program Files/Tesseract 4.0.0/tesseract.exe"
The tesseract_cmd is required if no properly search PATH setup in your Windows PC.
Hope this help.
UPDATE:
You need to have tesseract binary installed into your PC before using pytesseract which uses subprocess module to run tesseract in Windows shell from Python.
Click this Tesseract 4.00 alpha to download a 64-bit Windows version and install it. Then setup the PATH and TESSDATA_PREFIX pointing to your tesseract.exe and ~\tessdata directory respectively.
If you need any other language trained data file, you can get it [here].
In case the ~\tessdata directory is not found in your Windows, you can create it manually and copy at least one traineddata file to there, such as eng.traineddata for English.
If tesseract is working, it will return the version information when you type tesseract -v in command prompt as below.
I am rather new to Linux (Ubuntu) and installing (Python) packages. I'm having trouble with mkvirtualenv and can not solve it:

Did I install something wrong?
This is likely a permissions error with your current logged in user on the Linux machine.
Try
sudo mkvirtualenv mysite70
This will often prompt for the password of the root user.
If that does not work, you may want to look at the article below:
http://noelusion.com/2013/Fixing-the-mysterious-virtualenv-error-IOError-invalid-Python-installation/
But note, that the article is a hack on a fairly specific instance.
I think I messed up the installation. I reinstalled Ubuntu, virtualenv etc. It works fine now.
Make sure your username has accents or special characters. If yes, change directory creating environments creating an environment variable WORKON_HOME with value equal to the new path. Ex .: C:\Envs

I recently got a new system and built it off of a time machine backup of my old system.
When I try to compile and run any app in the simulator I'm getting the following error returned to the console.

It worked fine yesterday on the old system. I ran a backup before transferring and then installed the new system off of the most recent backup. Not sure why it would work on the old system and not the new.
I ended up reinstalling xcode as the error referenced python. This solved the problem.
try deleting everything in build/iphone. Do NOT delete the build/iphone directory, just everything IN it. Restart Ti Studio and rebuild.
