Question

以下代码会在我的机器上重现错误：

from IPython.display import Audio
Audio(filename='sample.mp3')

笔记本无法执行或显示消息，在终端的日志中输出

错误不是特定于音频文件，使用其他音频文件或放入numpy数组会产生完全相同的错误。

我错过了什么？

Answer 1

有人建议由于pyzmq（https://github.com/CellProfiler/CellProfiler/issues/1676）的过时版本而生成相同的错误消息。通过pip安装最新版本的pyzmq已在我的系统中解决了这个问题。希望，这有帮助。

尝试使用IPython.display.Audio时，Jupyer Notebook会出现Cython错误
