The following complete example shows how to display a numpy array using Qt's QTableView via a custom model. python import sys from PySide6 import QtCore, QtGui, QtWidgets from PySide6.QtCore import Qt import numpy as np class TableModel(QtCore.QAbstractTableModel): def __init__(self...
yup. You can build a wxImage from a buffer, and numpy provides a bufferinterface, so they end up with them sharing the same memory, as long asyour numpy array is contiguous 24 rgb. I've enclosed a sample that generates a wx.Image from a numpy array,then every time you push the but...

We can create a formatter for NumPy arrays (1D or 2D) from ansitable import ANSIMatrix formatter = ANSIMatrix(style='thick') and then use it to format a NumPy array m = np.random.rand(4,4) - 0.5 m[0,0] = 1.23456e-14 formatter.print(m) yields ┏ ┓┃ 0 -0.385 -0.106 0.296 ...
