I am using Windows-10, Python 3.7, Pillow version 6.0.0, tkinter.
I developed a GUI tool which saves tkinter canvas as a PostScript using tkitner library, then converts it to PNG file using PIL (Pillow) library. On my Computer, I already have Ghostscript installed and my tool works just fine.
After distributing my tool with my collages, they can save the canvas as PostScript fine, but the tool then can't convert to PNG file and a anError arise regarding Ghostscript.
OSError: Unable to locate Ghostscript on paths
I would like to enable my Colleges of running the tool without the need of downloading Ghostscript on there machines.
I though then of including (bundling) the Ghostscript when creating py_app.exe using Pyinstaller.
Does anyone know how to do this, or have any other suggestions.
Below is the error message:

I need to generate a tree from a dictionary with python AnyTree package.so I have a dictionary like below structure.
data = {'name': 'xyz',
'children': [{'name': 'node1',
'children': [{'name': 'node2'}]}]}
This dictionary can grow as the program executes.issue that I'm facing right now is when i try to export the tree as a png with DotExporter(root).to_picture("data.png") it throws a file not found error like below

I have graphviz package installed and i am on python 3.7 with windows.
however using DotExporter(root).to_dotfile('root.dot') I can export the tree as a dot file and using an online converter I can convert dot file to an image.
but I need to export this as a png from my program.
I have already googled for similar issues and did all the suggestions and solutions there.any help or suggestion would be great,any other tree graphing tool also would be okay.
found a solution..
problem is with the graphviz python package.when you install graphviz with pip,graphviz python wrapper doesn't contain graphviz binary files.
so to solve this you need to manually download graphviz from their website and set it to path or install graphviz using conda.
alternate to this you can use pydot as a png exporter.and you can use dot file to generate a png with pydot.also pydot can be installed with pip.
Note: This was flagged as a potential duplicate of this, but the point of my question is that using textract doesn't work. I am looking either for (a) a way to get textract to work on windows 10 or (b) an alternate solution.
I am building a system that needs to read various types of files. I have set up pdfminer to read the .pdfs, and based on the process outlined here I installed textract, and I can now also read .docx files. However textract relies on antiword for reading .doc files and I cannot get this to work, even after following the directions here I could not find and install a working version of antiword. I do not have microsoft word installed on my machine, and I am running windows 10 with python 3.6.5. Is there any other way to read .doc files?
Here is the bug when running textract.process('d.doc') (ignore the first error, the file is definitely there):

From the 'Windows installation problem' series: https://github.com/deanmalmgren/textract/issues/194#issuecomment-507243521
After following the steps to 'install' antiword, I was facing the same problem as yours.
Restarting windows after setting up the environment path variable entirely solved this exact error message for me. (This was the last error I was facing for handling .doc files with textract)
Installation instructions extracted from https://github.com/deanmalmgren/textract/issues/194#issuecomment-506065817
"Install Antiword
(I followed Reading .doc file in Python using antiword in Windows (also .docx))
Go to https://www.softpedia.com/get/Office-tools/Other-Office-Tools/Antiword.shtml
Extract to c:\antiword (yes it's required to be in the root directory)
Add location to path like we did tesseract-ocr [basically add c:\antiword to the system path (environment variable)]"
I was able to get part of the text using olefile, but olefile ultimately only handles bytes and does not handle the encoding of Word .doc files. The solution is to use LibreOffice, see my other question here
I am packaging a Python 2.7 program with the lastest version of Pynsist.
I've created an installer.cfg file following this example.
But when I try to package my application running
pynsist installer.cgf
into the application folder it comes up with

/usr/lib/python2.7/dist-packages/pygame/rwobject.so
Put Windows packages in pynsist_pkgs/ to avoid this.
So the problem I think is with Pygame.
On Google there in nothing about this, but i cannot use others programs for packaging(eg. py2exe, pyinstaller ecc...).
Thanks and sorry for the bad english
Reposting as an answer, since it worked:
If you put pygame in packages=, it tries to copy it from your computer. But on your computer that's pygame for Linux, which won't work on Windows. If you instead put pygame in the pypi_wheels= bit of the config file, Pynsist will take care of downloading a Windows version for you.
Have a look at the pygame example in the Pynsist repository.
Most packages don't have this problem because they only contain Python code, which is the same files on all platforms. Pygame has compiled modules, which have to be compiled for the right platform.
I'm getting the error in the title when trying to run the example code below on Windows 10/Python 3.6.1/Sublime Text Editor 3. I made sure to set my MAGICK_HOME environment variable to point to where I manually installed ImageMagick. I made sure to only have 1 version of ImageMagick installed. I made sure FFMPEG, Numpy, imageio, Decorator, and tqdm were all installed.
Yes, the file "vidclip.mp4" exists. The desired behavior here is to simply clip the video and add text to the center as per the example on the github page, i.e. to simply run the code successfully.
Does anyone know what might be wrong?
Example code from github:
from moviepy.editor import *
video = VideoFileClip("vidclip.mp4").subclip(7,64)
# Make the text. Many more options are available.
txt_clip = ( TextClip("Ken Block who?",fontsize=70,color='white')
.set_position('center')
.set_duration(10) )
result = CompositeVideoClip([video, txt_clip]) # Overlay text on video
result.write_videofile("vidclip_edited.webm",fps=25) # Many options...

.This error can be due to the fact that ImageMagick is not installed on your computer, or (for Windows users) that you didn't specify the path to the ImageMagick binary in file conf.py, or.that the path you specified is incorrect
Found the problem. I didn't realize it was imperative that I specify the location of ffmpeg.exe and convert.exe within ImageMagick's config_defaults.py file. After that, I install MoviePy (in that order).
I have written a very long IPython notebook and need to convert it to PDF for distribution. I've read this thread but the solution didn't work for me.
I've tried the following:
If I use the Print button in my browser, I have all the IPython menu
etc. showing, which I can't accept.
If I use Print Preview from the IPython menu, none of the LaTeX equations render. They are all still just LaTeX code.
If I use ipython nbconvert --to latex --post pdf myfile.ipynb I get a FileNotFoundError. Traceback follows:

I'm using the latest updates from Anaconda in Python 3.4 64-bit on Windows 7 Professional.
Your issue is that you do not have LaTeX installed on your computer. When subprocess tries to call pdflatex myfile.tex it therefore fails as it cannot find pdflatex.
Whilst it's true that you can create .tex files from IPython notebooks without needing LaTeX, these are just files that contain the LaTeX code. To compile them to create PDFs you need a version of LaTeX.
Installing LaTeX on Windows is not difficult, MiKTeX is one possible installation.
