I am starting training new model with MMIE is on, I have copied the 2 files (Sphinx3_align and Sphinx3_decode ) .
training was stopped at MODULE: 61 Lattice Pruning
Phase 1: Cleaning up directories ...
logs...qmanager...pruned_denlat...
Phase 2: Posterior probability lattice pruning ...
with the following error

i tried all suggestions by other users of sphinx on the web
even i uninstall all sphinxbase,sphinxtrain and pocketsphinx and install fresh instalation of https://cmusphinx.github.io/wiki/download/
i installed
sphinxbase-5prealpha
pocketsphinx-5prealpha
sphinxtrain-5prealpha

but the problem is still exist

[hardworker]

the problem solved
i download sphinxbase 8, sphinxtrain 8 and build the dmp file using the new genertated sphinx_lm_convert tool
and problem solved

[hardworker]

now the MODULE: 62 Lattice Format Conversion Phase 2: Converting lattice format . collapsed with this error
