파이썬 word2vec bin 파일을 텍스트로 변환

누군가가 C 코드에 대한 수정이나 gensim이 텍스트를 내보내도록 지시 할 수 있습니까?

    len = 0;

    len = sqrt(len);
    for (a = 0; a < size; a++) M[a + b * size] /= len;
  }
  fclose(f);
  //Code added by Thomas Mensink
  //output the vectors of the binary format in text
  printf("%lld %lld #File: %s\n",words,size,file_name);
  for (a = 0; a < words; a++){
    printf("%s ",&vocab[a * max_w]);
    for (b = 0; b< size; b++){ printf("%f ",M[a*size + b]); }

  }  

  return 0;
}

printf 에서 "\ b \ b"를 제거했습니다.

그건 그렇고, 결과 텍스트 파일에는 여전히 텍스트 단어와 일부 숫자 계산에 원하지 않는 불필요한 공백이 포함되어 있습니다. bash 명령을 사용하여 각 줄에서 초기 텍스트 열과 후행 공백을 제거했습니다.
