QUESTION
I want to create and rasterize vector graphics in Python. I suspect that Pycairo or cairocffi (edit: or Qahirah) are a great choice. (If not, comments are welcome.)
What are the practical differences between the two?
Specifically, the Pycairo documentation says:
If Pycairo is not what you need, have a look at cairocffi, which is an API compatible package using cffi or Qahirah, which is using ctypes and provides a more "pythonic" API with less focus on matching the cairo C API.
But this raises some questions: In what cases may Pycairo be "not what you need", whereas cairocffi is? In what way are cffi/Qahirah/ctypes better than whatever Pycairo does instead? In what ways is Pycairo not "pythonic"? If cairocffi is better than Pycairo, why is Pycairo more popular, does it have advantages?
Edit: A comma might be missing after "cffi" in the quote above. In that case, it's not about "Pycairo vs. cairocffi", but about "Pycairo vs. cairocffi vs. Qahirah".

I have a problem installing a PyQt5 python package. I am in Yocto Linux environment (Hardknott kernel 5.10.35) on the Variscite board (DART-MX8M-PLUS). This is the log when I try to install with pip:

Answered 2022-Mar-01 at 15:02Do not bother installing packages natively on the board,
PyQt5 is already supported by Yocto in meta-qt5, link to recipe.

QUESTION
So I've done a bit of googling and looking at older threads here but I still have no idea how to do it. I've seen some other ways to clip Surfaces with drawn paths like in the context.clip method, but I haven't seen anything like it for two surfaces.
The thing I'd want is some way to draw some surface A to sone surface B in the places determined by some other surface C's alpha layer. I'm pretty new to PyCairo so I'd appreciate the help :)
...ANSWER
Answered 2022-Feb-16 at 16:06You are looking for cairo_mask_surface: https://www.cairographics.org/manual/cairo-cairo-t.html#cairo-mask-surface
I do not know how this is accessible in PyCairo, but I would guess ctx.mask_surface(surf_c).

QUESTION
I am working with pycharm community on a tensorflow model with keras backend, sometimes this error appears in a random time, specially after I call pyplot and close the window:
...ANSWER
Answered 2021-Nov-30 at 20:26Looks like this is part of an actively tracked issue with Tkinter in PyCharm. You can find the reference on the Pycharm's developer's issue tracker. The issue is undiagnosed, but if looking at similar problems with Tk on StackOverflow, one can see that it's an issue with thread safety and/or multithreading.
All I can do is speculate as to the cause, which is not helpful, however, I can at least collate the suggested workarounds:
Switch to a different Matplotlib backend (See docs: What is a backend?). Such as Qt5, but you will need to make sure they are available in your environment.
This approach is the most promising as other backends are better able to deal with not being the main thread or are explicitly safe for multi-threading. It's also the simplest unless you have a really specific reason for preferring TkAgg.
Do not use the debugger with interactive plots.
Set "Variables Loading Policy" to "Synchronously" in Debugger as suggested by a PyCharm dev in the linked issue.
Enable "Scientific mode" in Pycharm.
More esoteric workarounds such as closing your figures within the code before drawing the second one. Example, after plotting the first figure:
QUESTION
I have a subclassOf hierarchy that can be represented as a dataframe. subjects are subclasses of objects. I would like to print it as an indented list, where indentation means that the term is a subclass of the term on the line above. I'm using a recursive function and feel like I'm pretty close: I can indent in, but I don't think I've found the right place to indent out (by decrementing prefix_level).
Apologies if this question isn't organized real well. I'm open to any solution. It doesn't have to build on what I've shown here.

QUESTION
Hi I am middle school student and trying to download something called Pycario, in order to use manim for my math project. However, I am facing some problems.
I have downloaded python3.9.0, and downloaded .whl file named pycairo‑1.20.1‑cp310‑cp310‑win32.whl( my computer is not-amd, and 64bit)
Then, I tiped in cmd: pip install pycairo-1.20.1-cp39-cp39-win32
I expected successful download, but instead I got:
ERROR: Could not find a version that satisfies the requirement pycairo-1.20.1-cp39-cp39-win32 (from versions: none) ERROR: No matching distribution found for pycairo-1.20.1-cp39-cp39-win32
I am sure that I downloaded the correct .whl file, but I can not download pycario and do not know why.
I know literally nothing about programming, somebody pls help!
...ANSWER
Answered 2021-Sep-08 at 01:26You need to include the .whl in the filename.

ANSWER
Answered 2021-Aug-20 at 18:37It is very likely that pip3 is pointing to a different python instance.
Imagine you had python, python3, python3.6 and python3.8 all installed on your system. Which one would pip3 install packages for? (who knows?)
It is almost always safer to do python3.8 -m pip list/install since you can be sure that python3.8 somefile.py will be using the same files you just saw. (even better, do python3.8 -m venv /path/to/some/virtualenv and then make sure that is activated, then you can be sure pip points to the same python)
