我已经和它斗争了很长一段时间了。我正在尝试安装Yaafe以进行音频功能提取。我按照此处的说明操作:https://github.com/Yaafe/Yaafe
一切安装得很好,但是当我尝试运行测试文件“frames.py”时,我收到以下错误:
File "frames.py", line 6, in <module>
from yaafelib import FeaturePlan, Engine, AudioFileProcessor
File "/usr/local/lib/python2.7/dist-packages/yaafelib/__init__.py", line 36, in <module>
from yaafelib.core import (loadComponentLibrary,
File "/usr/local/lib/python2.7/dist-packages/yaafelib/core.py", line 35, in <module>
yaafecore = cdll.LoadLibrary('libyaafe-python.so')
File "/usr/lib/python2.7/ctypes/__init__.py", line 443, in LoadLibrary
return self._dlltype(name)
File "/usr/lib/python2.7/ctypes/__init__.py", line 365, in __init__
self._handle = _dlopen(self._name, mode)
OSError: libyaafe-python.so: cannot open shared object file: No such file or directory
我已将lib目录包含在LD_LIBRARY_PATH中,并带有以下命令:
export LD_LIBRARY_PATH=/usr/local/lib
事实上,当我回应LIBRARY_PATH时,它就在那里。另外,当我检查/ usr / local / lib时,它有以下内容:
libyaafe-components.so libyaafe-io.so python2.7
libyaafe-components.so.0 libyaafe-io.so.0 python3.4
libyaafe-components.so.0.70.0 libyaafe-io.so.0.70.0 site_ruby
libyaafe-core.so libyaafe-python.so yaafe
libyaafe-core.so.0 libyaafe-python.so.0
libyaafe-core.so.0.70.0 libyaafe-python.so.0.70.0
所以不应该一切都好吗?我不明白是什么问题。我已按照说明进行操作。
答案 0 :(得分:4)
更改代码,以便在异常发生之前打印os.environ
。这样,您将看到Python进程是否具有正确的环境集。要检查的另一个显而易见的事情是,您的Python进程是否具有足够的权限来打开和读取libyaafe-python.so
。请注意,出于安全原因,默认情况下sudo
会限制被调用命令的环境(例如,请参阅here)。
