Import Error: cannot import name 'GraphSequence' from 'nfp.preprocessing'

机器学习，重复他人代码过程中出现问题

import pickle
import gzip

with gzip.open('processed_inputs_190531.p.gz', 'rb') as f:
    preprocessor_data = pickle.load(f)
    
preprocessor = preprocessor_data['preprocessor']
inputs = preprocessor.predict(rdf.molecule.unique())

运行结果及报错内容

非常需要大家的帮助，非常感谢!

from nfp.preprocessing import GraphSequence这个可能是nfp的版本升级导致部分语法变更了，你试试降低nfp版本

nfp你安装了吗？
