How do I deserialize dicts in Python using NumPy?

In Python, when you want to deserialize dictionaries, especially those containing NumPy arrays, you can use the `numpy` library along with `json` or `pickle` for serialization. Here's how to do it:

First, ensure you have NumPy installed:

pip install numpy

Then, you can use the following example to deserialize a dictionary that includes NumPy arrays:

import numpy as np import json # Example of a dictionary with a NumPy array data = { 'array': np.array([1, 2, 3]), 'value': 42 } # Serialize the dictionary into a JSON string data_serialized = json.dumps(data, default=lambda x: x.tolist() if isinstance(x, np.ndarray) else x) # Deserialize the JSON string back into a dictionary data_deserialized = json.loads(data_serialized) # Convert the list back to a NumPy array data_deserialized['array'] = np.array(data_deserialized['array']) print(data_deserialized) print(type(data_deserialized['array']))
