I am trying to run Pocketsphinx on a microcontroller running uClinux, I have installed pocketsphinx on the controller, but I keep getting several different errors regarding acoustic models and definitions. The current one I am facing is:
"Phone ... is missing in the acoustic model"
Replace the ... with every possible phonetic combination. It starts
off with A, then AE, then progresses to B etc.
I am trying to take a .wav file as input, and so this is the command I am using to run the software:
pocketsphinx_continuous -hmm /usr/share/pocketsphinx/model/hmm/en/tidigits/ -lm /usr/share/pocketsphinx/model/lm/en/tidigits.DMP -infile 1.wav -samprate 8000 -dict cmu07a.dic
Has anyone encountered this issue? if so, do you know a way to resolve it?
For tidigits model there is a special dictionary tidigits.dic in pocketsphinx/model/lm/en/tidigits.dic, you need to use with -dict option instead of cmu07a.dicin your command line.

I have upgraded my dbt version to 1.0.0 yesterday night and ran few connection test. It went well . Now when i am running the my first dbt example model , i am getting below error , even though i have not changed any code in this default example model.
Same error i am getting while running dbt seed command also for a csv dataset . The csv is utf-8 encoded and no special character in it .
I am using python 3.9
Could anyone suggest what is the issue ?
Below is my first dbt model sql
After lots of back and forth, I figured out the issue. This is more like fundamental concept issue.
Every time we execute dbt run, dbt will scan through the entire project directory ( including seeds directory even though it is not materializing the seed ) [Attached screenshot below].
If it finds any csv it also parsed it .
In case of above error, I had a csv file which looks follows :
If we see the highlighted line it contains some symbol character which dbt (i.e python) was not able to parse it causing above error.
This symbol was not visible earlier in excel or notepad++.
It could be the issue with Snowflake python connector that #PeterH has pointed out .
As temporary solution , for now we are manually removing these character from Data file.
I’d leave this as a comment but I don’t have the rep yet…
This appears to be related to a recently-opened issue.
https://github.com/dbt-labs/dbt-snowflake/issues/66
Apparently it’s something to do with the snowflake python adapter.
Since you’re seeing the error from a different context, it might be helpful for you to post in that issue that you’re seeing this outside of query preview.
The goal is:
Control smart house via predefined text commands. Without any activation word like okay google, it always listening.
What's done:
pocketsphinx_continuous -inmic yes -hmm /path/zero_ru.cd_cont_4000 -dict /path/my_dictionary_out -lm /path/lmbase.lm.DMP
Where my_dictionary_out has using words one by one. And it works, but I think KWS mode might be better. So I've written a text file like:
включи свет комнате /1e-50/
выключи свет комнате /1e-50/
and trying to run sphinx without language model (-lm option), but got nothing. It doesn't recognize commands from keywords file.
What's wrong?
I need an application that prints/visualizes input/output pairs during the FST runs. I mean, for each state of the fst, it needs to print out a tuple that contains input for that state and output of the state. Right now I can generate fst files that is compatible with foma,hfst and xfst fst tools. So, I guess the visualization tool I need should be enough to compatible with any of them. Is there anyone who knows such a tool ?
foma can produce dot format files that can be visualized by graphviz. On Debian/Ubuntu, install graphviz with
$ sudo apt-get install graphviz
foma can read att format files (produced with hfst-fst2txt for anything HFST can read, or lt-print for anything from lttoolbox); assuming you've got such a file named myfst.att, you can do
$ foma
foma[0]: read att myfst.att
foma[1]: view
to display the full FST. That will show each input/output pair on each edge between states of the FST.
But you say "during runs" – are you talking about also showing the queue of "live states"? If so, I don't know of a tool that does this, that would be nice! One thing you could do is to modify the HFST source to output the list of live states and string vectors as it's processing, and then combine that with the dot file to e.g. colour in the live states. (If so, you may want to take this to the #hfst channel on irc.freenode.net.)
There is also a script att2dot.py on https://ftyers.github.io/2017-%D0%9A%D0%9B_%D0%9C%D0%9A%D0%9B/hfst.html that can be used on the command line like
hfst-fst2txt chv.lexc.hfst | python3 att2dot.py | dot -Tpng -ochv.lexc.png if you prefer something more scriptable. If you use that from the Python library of HFST, you might be able to get the "live states" for every part of an analysis more easily.
Am trying to use NEOS to solve a linear program using MPS input.
The MPS file is fine, but apparently you need a "paramaters file" as well to tell the solver what to do (min/max etc.). However I can't find any information on this online anywhere.
So far I have got NEOS to solve a maximization problem and display the objective function. However I cannot get it to display the variables.
Does anyone know what code I should add to the paramters file to tell NEOS/CBC to display the resulting variables?
The parameter file consists of a list of Cbc (standalone) commands in a file (one per line). The format of the commands is (quoting the documentation):
One command per line (and no -)
abcd? gives list of possibilities, if only one + explanation
abcd?? adds explanation, if only one fuller help(LATER)
abcd without value (where expected) gives current value
abcd value or abcd = value sets value
The commands are the following:
? dualT(olerance) primalT(olerance) inf(easibilityWeight)
integerT(olerance) inc(rement) allow(ableGap) ratio(Gap)
fix(OnDj) tighten(Factor) log(Level) slog(Level)
maxN(odes) strong(Branching) direction error(sAllowed)
gomory(Cuts) probing(Cuts) knapsack(Cuts) oddhole(Cuts)
clique(Cuts) round(ingHeuristic) cost(Strategy) keepN(ames)
scaling directory solver import
export save(Model) restore(Model) presolve
initialS(olve) branch(AndBound) sol(ution) max(imize)
min(imize) time(Limit) exit stop
quit - stdin unitTest
miplib ver(sion)
To see the solution values, you should include the line sol - after the min or max line of your parameter file.
If this doesn't work you can submit the problem to NEOS in AMPL format via this page. In addition to model and data files, it accepts a commands file where you can use statements to solve the problem and display the solution, for example:
solve;
display _varname, _var;
This post describes how to convert MPS to AMPL.
I'd like to be able to "up-arrow" to commands that I input in a previous Python interpreter. I have found the readline module which offers functions like: read_history_file, write_history_file, and set_startup_hook. I'm not quite savvy enough to put this into practice though, so could someone please help? My thoughts on the solution are:
(1) Modify .login PYTHONSTARTUP to run a python script.
(2) In that python script file do something like:
def command_history_hook():
import readline
readline.read_history_file('.python_history')
command_history_hook()
(3) Whenever the interpreter exits, write the history to the file. I guess the best way to do this is to define a function in your startup script and exit using that function:
def ex():
import readline
readline.write_history_file('.python_history')
exit()
It's very annoying to have to exit using parentheses, though: ex(). Is there some python sugar that would allow ex (without the parens) to run the ex function?
Is there a better way to cause the history file to write each time? Thanks in advance for all solutions/suggestions.
Also, there are two architectural choices as I can see. One choice is to have a unified command history. The benefit is simplicity (the alternative that follows litters your home directory with a lot of files.) The disadvantage is that interpreters you run in separate terminals will be populated with each other's command histories, and they will overwrite one another's histories. (this is okay for me since I'm usually interested in closing an interpreter and reopening one immediately to reload modules, and in that case that interpreter's commands will have been written to the file.) One possible solution to maintain separate history files per terminal is to write an environment variable for each new terminal you create:
def random_key()
''.join([choice(string.uppercase + string.digits) for i in range(16)])
def command_history_hook():
import readline
key = get_env_variable('command_history_key')
if key:
readline.read_history_file('.python_history_{0}'.format(key))
else:
set_env_variable('command_history_key', random_key())
def ex():
import readline
key = get_env_variable('command_history_key')
if not key:
set_env_variable('command_history_key', random_key())
readline.write_history_file('.python_history_{0}'.format(key))
exit()
By decreasing the random key length from 16 to say 1 you could decrease the number of files littering your directories to 36 at the expense of possible (2.8% chance) of overlap.
I think the suggestions in the Python documentation pretty much cover what you want. Look at the example pystartup file toward the end of section 13.3:
http://docs.python.org/tutorial/interactive.html
or see this page:
http://rc98.net/pystartup
But, for an out of the box interactive shell that provides all this and more, take a look at using IPython:
http://ipython.scipy.org/moin/
Try using IPython as a python shell. It already has everything you ask for. They have packages for most popular distros, so install should be very easy.
Persistent history has been supported out of the box since Python 3.4. See this bug report.
Use PIP to install the pyreadline package:
pip install pyreadline
If all you want is to use interactive history substitution without all the file stuff, all you need to do is import readline:
import readline
And then you can use the up/down keys to navigate past commands. Same for 2 or 3.
This wasn't clear to me from the docs, but maybe I missed it.
