我正在尝试部署一个使用 TensorFlow 和 Librosa 的烧瓶应用程序。因此，作为 Librosa 的依赖项，我需要sndfile包。

当我运行我的 Flask 应用程序时，我收到此错误：

import librosa
  File "/home/ec2-user/.local/lib/

python3.7/site-packages/librosa/__init__.py", line 211, in <module>
    from . import core

  File "/home/ec2-user/.local/lib/python3.7/site-packages/soundfile.py", line 142, in <module>
    raise OSError('sndfile library not found')
OSError: sndfile library not found

我试过了：

sudo yum install autoconf autogen automake build-essential libasound2-dev \
   libflac-dev libogg-dev libtool libvorbis-dev libopus-dev libmp3lame-dev \
   libmpg123-dev pkg-config python

然后我收到这条消息：

Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
No package build-essential available.
No package libasound2-dev available.
No package libflac-dev available.
No package libogg-dev available.
No package libvorbis-dev available.
No package libopus-dev available.
No package libmp3lame-dev available.
No package libmpg123-dev available.
No package pkg-config available.

我知道该软件包在 Amazon EC2 实例中不可用。谁能指导我如何将 sndfile 包安装到系统中？

亚马逊 Linux 2

我在Amazon Linux 2上，您可以通过在 EC2 服务器上运行以下命令来验证。

[ec2-user@fake-ip ~]$ cat /etc/system-release
Amazon Linux release 2 (Karoo)

可以从Amazon 包存储库获得以下包：libsndfile-devel、libsndfile-utils、libsndfile。

 [ec2-user@fakeip ~]$ yum search libsndfile
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
=============================================== N/S matched: libsndfile ================================================

libsndfile.i686 : Library for reading and writing sound files

亚马逊 Linux AMI

根据Amazon Linux AMI 软件包列表，此早期版本的 Amazon Linux 没有 libsndfile。尽管您可以启用 Extra Packages for Enterprise Linux (EPEL)，但 libsndfile 似乎也不存在。

[ec2-user@fakeip ~]$ cat /etc/system-release

[ec2-user@fakeip ~]$ sudo yum-config-manager --enable epel

libsndfile文档声明它已在Debian/GNU Linux上编译，但 Amazon Linux AMI 不是基于 Debian。libsndfile ( autoconf autogen automake build-essential libasound2-dev libflac-dev libogg-dev libtool libvorbis-dev libopus-dev libmp3lame-dev libmpg123-dev pkg-config python) 的构建依赖项都引用了 Debian 软件包，这些软件包在其他 Linux 风格中没有相同的名称。特别是 , , build-essential,和不在EPEL 上。libasound2-devlibflac-devlibopus-devlibmp3lame-devlibmpg123-dev

[ec2-user@fakeip ~]$ yum search autoconf autogen automake build-essential \

建议

  • 将您的 EC2 切换到 Amazon Linux 2 或 Ubuntu
  • 在 EC2 上的 Docker 映像中运行您的应用程序

您需要安装 libsndfile 及其开发文件。不幸的是，它没有打包在存储库中，但是您可以通过直接下载 RPM 来安装它

wget http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic//libsndfile-1.0.31-alt1.x86_64.rpm
wget http://ftp.altlinux.org/pub/distributions/ALTLinux/Sisyphus/x86_64/RPMS.classic//libsndfile-devel-1.0.28-alt1.x86_64.rpm

sudo yum localinstall libsndfile-devel-1.0.31-alt1.x86_64.rpm

您还可以从源代码安装libsndfile。

另一种选择是切换到 Ubuntu，其中包含libsndfile和libsndfile-dev. 如果您希望专门部署 tensorflow，那么您应该从AWS Deep Learning AMI开始。这些 AMI 由 AWS 构建，并附带驱动程序和一系列已安装的框架。这些 AMis 具有 Ubuntu 风格的版本。
