i am new to programming and dont understand calling the final code playlist.py to read specified files. how do i run the programme?

EDIT: After the installation of Ghostscript 9.50, which I obtained from
https://pages.uoregon.edu/koch/Ghostscript-9.50-Full.pkg,
the program writes the png file as expected on key "s" -- PIL requires the presences of Ghostscript, which is not provided with the purchase of a Mac.

Using python 3.8.1 and the current version of PIL:
on keys "t" or " ", the program toggles or restarts as expected.
on key "s", the program writes the .eps file, but it does not write the .png file. The program continues to run and produces the following error message when it fails to write the png file.

Ref to code in folder volrender

The files raycast.py, raycube.py, slicerender.py import another module called glutils but the module is no where found in the code.

Thanks the book has been an engrossing read so far !

I'm attempting to work through the Volume Rendering chapter. Love the book! This may be a driver or system error but any tips for teasing out this error would be greatly appreciated!

1. I'm using windows7 64 bit and python 3.4 64bit (I made sure with platform.architecture())
2. I downloaded the 64bit glfw binaries from http://www.glfw.org/download.html
3. I copied glfw3.dll from the libvc-2012 folder into volrender.py and hardcoded the path to the dll in volrender.py. That seems to be working because glfw.glfwInit() returns 1
4. I get "invalid operation' error when it get to the glViewport() call.

The code presents the following error:

anatomyPlaylist.py:16: DeprecationWarning: The readPlist function is deprecated, use load() instead
plist = plistlib.readPlist(fileName)

I've changed the line:

plist = plistlib.readPlist(fileName)

to

plist = np.load(fileName)

but, the error changed to:

return pickle.load(fid, **pickle_kwargs)_pickle.UnpicklingError: invalid load key, '\x0a'.

During handling of the above exception, another exception occurred:

e-packages\numpy\lib\npyio.py", line 443, in load
"Failed to interpret file %s as a pickle" % repr(file))
OSError: Failed to interpret file 'maya.xml' as a pickle

Of course there is some other modification to make, but I can't figure it out yet.

Advices?

Thanks and sorry for my poor english.

I found glfw a python module on pypi. So we can use it, stead of implementing it again.

I am using Spyder (Python 2.7) with Anaconda and trying to get volrender.py to work. I had to make one change. Anaconda likes pyglfw so i loaded this and changed 'import glfw' to 'import pyglfw as glfw'. This works.

Now when i try to compile and run, i get the following error:
Reloaded modules: raycube, volreader, glutils, slicerender, raycast
starting volrender...
usage: volrender.py [-h] --dir IMAGEDIR
volrender.py: error: argument --dir is required
An exception has occurred, use %tb to see the full traceback.
SystemExit: 2
entering %tb i get:

I would be most appreciative if i could get some advice on how to fix this.

OpenGL Version 	GLSL Version
2.0 	1.10
2.1 	1.20
3.0 	1.30
3.1 	1.40
3.2 	1.50
3.3+	3.30

The shader only actually needs very minor changes to work as a core profile 3.2 shader (1.50) and therefore work when opening a 3.2 context instead of 3.3

the code i used is same and code file are placed in /myProjectDir/ where all the jquery files are placed which are not loading.
https://raw.githubusercontent.com/electronut/pp/master/piweather/piweather.py

plz tell where to place the piweather.py file so that the server loads the jquery file and where to change the file.

i had created the issue :
bottlepy/bottle#1176
Issue is still not fixed.

When I press "s", the console shows:

I opened the folder, finding the picture was not be saved as png.

Even with a simple playlist I made specifically for testing that only contains the same song 3 times, the code is not finding duplicates. Tried with the 'test files' too - same result. Issue appears to be that the xml file only lists the tracks once, and then refers to them as many times as required further down in the Playlist Items dictionary. The code looks for duplicates in the Tracks dictionary - but the xml file doesn't repeat duplicates there, so the code always returns no duplicates.

Has the plist format changed since this code was written, or am I missing something else?

In the code listing, the shader code seems to be commented out??

I purchased a Kindle version of this book and it's a really useful book.
I'd like to use some of the project code to practice with OOP design and refactor (just for fun maybe). And I want to post them on my own repo in order to review my track better. I want to know is there any license for those projects. I can't find one in the repo.

My python: v3.6.1

python playlist.py --dup test-data/rating.xml

output:

...
TypeError: a bytes-like object is required, not 'str'

in findDuplicates(), changing

    f = open("dups.txt", 'wb')

to

    f = open("dups.txt", 'w')

will fix it.

EDIT: despite these error flags in PyCharm, the program does run.

at
https://github.com/electronut/pp/blob/master/spirograph/spiro.py

in lines 116, 117, and 127
the PyCharm (Python 3.8.1) flags the methods turtle.window_width(), turtle.window_height(), and turtle.ontimer(...) with an unresolved reference error.

In project photomosaic.py, in line 180:

if not reuse_images: 
    input_images.remove(match)

I wonder variable ‘match' is miswritten. it is never defined in codes. But I don't know what it should be replaced?

hi sir,i executed laser.py in windows in a cmd but when i given --port COM3 executed.
but ,small error saying
AttributeError:'module' object as no attrubute 'Serial'

test1 is presumbly the python way to apply the rules, where test2 is numpy way. Would be helpeful to see both versions and compare.

When I execute the ks.py file downloaded from here using --display --play, the random tones play as expected, however, when I use only the --play parameter, it creates/skips files but no random tones are played. Also, when using --display, the plot appears, but remains blank, unless I run it in a debugger. I'm using Python 2.7.12, and there are no exceptions or errors appearing in the console. Is this a python 2.7 vs 3 issue?
