编译decoder_test.py时我不能使用pocketsphinx api：
from pocketsphinx.pocketsphinx import *
ImportError: No module named pocketsphinx
如文档中所述，我已经正确安装了pocketsphinx和sphinxbase，
import pocketsphinx效果很好。但是在调用Decoder函数时出现错误AttributeError: 'module' object has no attribute 'Decoder'

如果你看到不同的东西，你有较旧的 pocketsphinx 安装，你没有配置 python 加载路径或者你没有正确安装 pocketsphinx。
