when load the model, Null point always returned.

hello, first thanks for the nice framework.

the extraction of mfcc and first, second-order delta feature works well.
After that, when I load the model(.hsmm)

the Error: failed to load model from blah blah

.. error is occurred.

Some model file(empty.hsmm) doesn't occur above error.
And i made some test.txt or text.hsmm file and change the from path to test file to check the fopen function in hsmm = load_model(optarg) in shiro-rest.c whether it works well. But it also got an error!

fopen return success by checking 'perror', it returns 'Success'. the custom c file i made also can read any .hsmm and test.txt.
but it doesn't works only in your shiro-rest.c code.

I can't resolve this situation, how can i resolve this problem?

Hello. How did you create flat.hsmm? Would you share the file for an inspection?

I just follow up your kind instruction.
like this
lua shiro-mkseg.lua index.csv \ -m phonemap.json \ -d "../cmu_us_bdl_arctic/orig/" \ -e .param -n 36 -L sil -R sil > unaligned-segmentation.json ./shiro-init \ -m empty.hsmm \ -s unaligned-segmentation.json \ -FT > flat.hsmm

All of your instruction doesn't seem to got error.
I just download the CMU Arctic speech database and change the some instruction path. for example 'cmu_us_bdl_arctic/orig/' to 'cmu_us_bdl_arctic/wav/'(i can't find the orig path in dataset. i guess the wav path directory from orig to wav)

At first time, i try to inference the below code(I use ./examples/cmu-arctic-all-speakers.hsmm model instead trained-model.hsmm). but it also can't load the model. so i decide to train the another model through your training instructions.
./shiro-align \ -m trained-model.hsmm \ -s unaligned.json \ -g > initial-alignment.json ./shiro-align \ -m trained-model.hsmm \ -s initial-alignment.json \ -p 10 -d 50 > refined-alignment.json

Sorry for my mistake to run the your instrunment.

I replace the path from "/cmu_us_bdl_arctic/orig/" to "/cmu_us_bdl_arctic/wav/".
But, the right way to modify is changing to "/cmu_us_bdl_arctic/wav"(please remove '/').
Finally, like the below figure, the training is successful!

All of top to end are work very well.
nice code!
Thanks a lot!
