如何将保存的Keras .h5文件转换为csv文件或.mat文件

import numpy as np
import pandas as pd
from scipy.io import savemat
from keras.models import load_model

model = load_model('path_to_model.h5')

weights = model.get_weights()

df = pd.DataFrame(weights)
df.to_csv('path_to_weights.csv', index=False)

savemat('path_to_weights.mat', {'weights': weights})
