python midi模块用哪个命令读取文件？

我在github下了一个AI写歌的python源代码所有depengdencies都安装完后运行时提示 我dir了一下midi模块发现确实没有read__midifile命令，我尝试了types，midi，utils反馈是都是同样的反馈。现在实在不清楚该用哪个命令读取midi文件或者是我理解错了，这里不是读取文件

import midi
import numpy as np


lowerBound = 24
upperBound = 102
span = upperBound-lowerBound


def midiToNoteStateMatrix(midifile, squash=True, span=span):
    pattern = midi.read_midifile(midifile)

    timeleft = [track[0].tick for track in pattern]

    posns = [0 for track in pattern]

    statematrix = []
    time = 0

    state = [[0,0] for x in range(span)]
    statematrix.append(state)
    condition = True

        ```

附上出错的代码的上下文

兄弟问一下midi咋安装啊，我愣是没装上，import不出来啊
