The problem was solved by adding this code class NumpyEncoder(json.JSONEncoder): """ Special json encoder for numpy types """ def default(self, obj): if isinstance(obj, np.integer): return int(obj) elif isinstance(obj, np.floating): return float(obj) elif isinstance(obj, np.ndarray): return obj.tolist() return json.JSONEncoder.default(self, obj) and json.dump(Logval, f,cls=NumpyEncoder)
