aishell運行報錯，提示需安裝kaldi-lm
local/aishell_train_lms.sh: train_lm.sh is not found. That might mean it's not installed
local/aishell_train_lms.sh: or it is not added to PATH
local/aishell_train_lms.sh: Use the script tools/extra/install_kaldi_lm.sh to install it
安裝kaldi-lm後，顯示如下信息：
Installation of kaldi_lm finished successfully
Please source tools/env.sh in your path.sh to enable it
在aishell的s5目錄下的path.sh最後增加一行信息即可：
export PATH=$PATH:/data1/kaldi-master/tools/kaldi_lm
其中/data1/kaldi-master/爲kaldi的安裝目錄，替換爲用戶自己的目錄即可
