NoteSequence Protobuf解碼錯誤

我試圖導入一個NoteSequence文件到洋紅色，並得到 'google.protobuf.message.DecodeError：意外的結束組標記。'NoteSequence Protobuf解碼錯誤

get_seq.py

from os import path 
import sys 
import os 

sys.path.append(path.relpath("../../bazel-out/local-fastbuild/bin/magenta/convert_midi_dir_to_note_sequences.runfiles/")) 

import midi_io 
import note_sequence_io 
import pretty_midi 
import protobuf 
import tensorflow as tf 

file_path = path.relpath("../../out/conv/in.seq") 

sys.path.append(path.relpath("../../bazel-genfiles/magenta/protobuf")) 
import music_pb2 

def read_file_generator(filename): 
    f = open(filename, 'r') 

    for line in f: 
      yield line.rstrip('\n') 
    f.close() 

generator = read_file_generator(file_path) 

for i in generator: 
    print music_pb2.NoteSequence.FromString(i)

這應打印樣系：

如何檢索預期protobufs？

此問題不再適用於包含編碼器，旋律和模型的最新版本。我試圖直接導入協議緩衝區，這不是最佳實踐。 –

FromString需要一個序列化的protobuf，而不是一個ASCII格式的。您可以使用以下功能從ASCII解析：

from google.protobuf import text_format 

def parse_test_proto(proto_type, proto_string): 
    instance = proto_type() 
    text_format.Merge(proto_string, instance) 
    return instance
