Re: [Kaldi-developers] python wrappers for Kaldi

Hi all.
>From a first look, it does look very impressive, and nicely documented.
I would appreciate it if people on the list who have Python experience
would comment on this- you can either reply to this thread, or to me.
I don't know if this has been done in the "natural" way, or if there
is some reason why people in the future will say, "why did you do it
this way, you should have done XXX".

Jan:
in the scripts/ directory you seem to have some examples of how you
can create python programs that behave very much like Kaldi
command-line programs, using your framework.  This is very useful.
However, the programs
 apply-global-cmvn.py
 compute-global-cmvn-stats.py
are perhaps a little confusing because they provide the same
functionality that you could get with "compute-cmvn-stats ->
matrix-sum" and "apply-cmvn" on the output of that command; and they
do so using different formats for the CMVN information.  I know the
format of storing the CMVN stats in a two-row matrix is perhaps not
perfectly ideal, but it's a standard within Kaldi and it would be
confusing to deviate from that standard.
Of course, this is a very minor issue that doesn't affect the validity
of the framework as a whole.  I am just pointing this out; the main
discussion should be about the framework and whether people feel it's
the "right" way to do this.
