Prune Trees: Index cells exhausted....

[Nagendra Kumar Goel]

Hi All,
I am making my first system using Sphinx using the scripts that come with sphinxtrain. At step 6,
I get this error message.

Can anybody give me a pointer as to why this message is generated? I looked at the questions file generated by the training script, and it looked like very normal phonetic questions.

best regards

hello group,
I was looking into the the problems of mk_mdef_gen and found the following:

The call sequence is mk_mdef_gen line 889 it
calls ac_mod_set_add_tri. This is after adding the ci phones to the list. the total number of calls in the for loop is 99831 or the # of triphones.

after 37234 calls I get the message "index_cells_exhausted".
Interestingly lines 864 and 865 do have the correct hint values (40) and 99831.
