QUESTION
Many well-known python libraries are basically written in C (like tensorflow or numpy) because this apparently speeds things up a lot. I was able to very easily integrate a C function into python by reading this.
Doing so I can finally use distutils
to access the functions of the source.c
file:
ANSWER
Answered 2021-Mar-09 at 11:29The shared libraries are the right way to go in this case. The distutils
have ability to build the static libraries as follows:

Answered 2021-Feb-11 at 19:52The tutorial has too many gaps. I think a view of the insides of Naive Bayes without reading a whole book is better found at https://machinelearningmastery.com/naive-bayes-classifier-scratch-python/ . I am not persisting with the tutorial and I advise others to avoid it.

QUESTION
I have several numpy matrices collected over some time. I now want to visualize these matrices and explore visual similarities among them. The matrices contain small numbers from 0.0 to 1.0.
To compare them, I want to ensure that the same "areas" get colored with the same color, e.g. that 0.01 to 0.02 always is red, and 0.02 to 0.03 always is green. I have two question:

adds new axis so you'll be able to divide sum of all columns in each row - it is the same as using np.sum(a,axis=1)[:,np.newaxis]
- when you sum all columns with np.sum(a,axis=1)
you'll get 1d array with shape (5000)
, but to be able to normalize your matrix with summed columns you need 2d array with shape (5000,1)
, that's why new axis is needed.
You can have fixed colors by fixing scale of your colormap: plt.pcolor(max_a,vmin=0,vmax=1)
adding discrete colorbar might also help:

Question
Is it possible to call a C DLL with a pointer to a 3dim array via Ctypes?
Progress
First off, I'm quite new to C and DLLs, so I might not know/have overseen something trivial.
I've got it to run with a pointer to a 1dim array. However it would be really nice to be able to use a 3dim array because I want to manipulate RGB image data, which does need edge repetition.

...ANSWER
Answered 2021-Jan-13 at 17:16Numpy arrays are stored in the same memory orientation as C arrays by default. On the Python side you can work with 3D arrays, but it's easier on the C side to treat as a 1D array and do the math to access rows and columns.
Example below requires a 3D numpy array as an argument, but passes the dimensions so the C code can access the elements. The C code modifies the array in-place:

Install Python-Code
You can use Python-Code like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
