viiew 🧐

pip install viiew to quickly view(your_data) in the terminal!

your_data can be a

• 2D NumPy array
• pandas DataFrame
• 2D PyTorch Tensor
• 2D jax array
• 2D tinygrad Tensor
• list of lists

As shown in the GIF, just call view...

import numpy as np
from viiew import view

x = np.arange(256).reshape(16, 16)
view(x)

...and e.g. press s to scroll through x (see all keybindings)!

view calls view_array and pressing s adds 1 to its row0 argument.

• ncols: Number of columns to display (default: 10)

• order: Sorting order (0: none, 1: ascending, -1: descending) (default: 0)
• color: Whether to use color coding for values (default: True)
• is_table: Whether to treat the data as a table (auto-detected for pandas DataFrames) (default: None)
• expand: Expansion level for columns (default: 0)
