import numpy as np
import codecs, json 

a = np.arange(10).reshape(2,5) # a 2 by 5 array
b = a.tolist() # nested lists with same data, indices
file_path = "/path.json" ## your path variable
json.dump(b, codecs.open(file_path, 'w', encoding='utf-8'), separators=(',', ':'), sort_keys=True, indent=4) ### this saves the array in .json format

python object of type set is not json serializable

Comment

Use the jsonpickle module to make Python set JSON serializable
Steps:
    1- Install jsonpickle using pip. pip install jsonpickle
    2- Execute jsonpickle.encode(object) to serialize custom Python Object.
Example:
import json
import jsonpickle
from json import JSONEncoder
sampleSet = {25, 45, 65, 85}

print("Encode set into JSON using jsonpickle")
sampleJson = jsonpickle.encode(sampleSet)
print(sampleJson)

# Pass sampleJson to json.dump() if you want to write it in file

print("Decode JSON into set using jsonpickle")
decodedSet = jsonpickle.decode(sampleJson)
print(decodedSet)

# to check if we got set after decoding
decodedSet.add(95)
print(decodedSet)

object is not json serializable

Comment

import json

# Define a custom JSON encoder class
class CustomEncoder(json.JSONEncoder):
    def default(self, obj):
        # Convert non-serializable objects to a serializable format
        if isinstance(obj, MyCustomObject):
            return obj.to_dict()  # Assuming the object has a to_dict() method to convert it into a dictionary
        return super().default(obj)

# Create an instance of the custom object
custom_obj = MyCustomObject()

try:
    # Attempt to serialize the object to JSON
    json_data = json.dumps(custom_obj, cls=CustomEncoder)
    print(json_data)
except TypeError as e:
    print("Error: Object is not JSON serializable")
    print(e)
