Open and view .npz file in Python

Python provides "npzviewer" to open .npz files

pip install npzviewer

npzviewer [-h] [-v] [npzfile]

https://pypi.org/project/npzviewer/

np.savez_compressed('filename.npz', array1=array1, array2=array2)
b = np.load('filename.npz')

And do b['array_1'], b['array_2'] and so on to retrieve data from each array.
