Loading Data with HyperSpy

This example demonstrates how to load and visualize data using the HyperSpy library.

import hyperspy.api as hs

from emdatabase.data import BilayerWS2

# Load a dataset using HyperSpy
dataset = BilayerWS2()
data_path = dataset.download()  # Download the dataset if not already available
data = hs.load(data_path)
data

WARNING | Hyperspy | This file contains a signal provided by the pyxem Python package that is not currently installed. The signal will be loaded into a generic HyperSpy signal. Consider installing pyxem to load this dataset into its original signal class. (hyperspy.io:949)
WARNING | Hyperspy | `signal_type='electron_diffraction'` not understood. See `hs.print_known_signal_types()` for a list of installed signal types or https://github.com/hyperspy/hyperspy-extensions-list for the list of all hyperspy extensions providing signals. (hyperspy.io:893)
