保存时间序列生成器类型keras.preprrocessing.sequence.TimeseriesGenerator

我试图保存一个test_generator，类型为（keras.processing.sequence.TimeseriesGenerator）

我使用了：

import pickle

test_generator

# Save data 
with open('/saved_file/filename.pickle', 'wb') as handle:
    pickle.dump(test_generator, handle, protocol=pickle.HIGHEST_PROTOCOL)

# Load data 
with open('/saved_file/filename.pickle', 'rb') as handle:
    test_generator_loaded = pickle.load(handle)

print(test_generator ==  test_generator_loaded)

>>>False

是否可以在不进行修改的情况下保存此类型的TimeseriesGenerator？？
