midi2audio / FluidSynth:[WinError 2]系统找不到文件

尝试调用midi2audio时出现FileNotFoundError错误。 我正在使用Python 3.6-Anaconda-Windows 10。 我的.py文件以及.sf2和.mid文件位于同一文件夹中。 我的代码是:

from midiutil.MidiFile import MIDIFile

from midi2audio import FluidSynth
soundfont = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\JR_sax.sf2'

filepath = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\input.mid'

fs = FluidSynth(sound_font=soundfont, sample_rate=22050)

fs.midi_to_audio(filepath, 'output.wav')

我希望在我的文件夹中创建一个.wav文件。 我得到了:

runfile('C:/Users/matteo.stante/Documents/4_Python_Scripts/experiments/AudioBello.py', wdir='C:/Users/matteo.stante/Documents/4_Python_Scripts/experiments')

FileNotFoundError: [WinError 2] Impossibile trovare il file specificato

1 个答案:

答案 0 :(得分:0)

soundfont = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\JR_sax.sf2'

filepath = 'C:\\Users\\matteo.stante\\Documents\\4_Python_Scripts\\experiments\\input.mid'
  • Windows: \\ (为什么2?因为\用于\ n \ r等格式,所以您需要2)
  • Linux: /

如果文件位于同一文件夹中,则

soundfont = 'R_sax.sf2'

filepath = 'input.mid'

编辑

我在PC(Windows 10)上尝试了此操作,但收到相同的错误。我在文档中没有找到有关操作系统的任何信息,但是显然有一些linux命令。

在Linux操作系统上尝试


EDIT2

我不费吹灰之力,并且也在Linux上进行了尝试。

1)错误相同-找不到文件

2)我发现您必须将文件夹放在路径-command的某个位置:$ PATH

  • 我把它放在/ usr / local / bin / fluidsynth

3)新错误:权限被拒绝(即使使用root用户也无法通过)

4)我发现我没有安装Fluidsynth

命令:易于安装fluidsynth

5)您的脚本有效(有点,output.wav生成了)

可能的解决方案

我相信问题-在Linux上安装Fluidsynth之后-在Windows上安装Fluidsynth后,您的Windows解决方案将得到解决。
