Could Japser work on OS X?

[vicramon]

I think it would be great if I could run Jasper on my Macbook. Would that be possible? I'm looking at the documentation and it seems like it could work with some extra configuration, but I don't know enough about the internals to know how if it's possible.

[fritz-fritz]

from what i've been reading/learning it seems possible though you may have trouble compiling and the instructions are not written for the mac terminal so you would have to enter the equivalent commands. (for example... no apt-get)

[qpaulson]

FYI.. I've spent about an hour trying to get it working with no luck yet..
The biggest issue I've run into is getting PocketSphinx installed and working.. If anyone gets past this step, please do post it here..

Here are my steps thus far:

1: Install Homebrew
install Homebrew:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

2: Install PIP
sudo easy_install pip

3: Install setuptools
sudo pip install --upgrade setuptools

4: Install Numpy
brew install homebrew/python/numpy

5: Install PyAudio
Availble here: http://people.csail.mit.edu/hubert/pyaudio/

6: Install PocketSphynx:
brew install cmu-pocketsphinx

7: Edit: jarvis/client/requirements.txt
Update: CherryPy==3.2.6
Update: argparse==1.1
Remove: PocketSphinx==0.8
Remove: SphinxBase==0.8
Remove: RPi.GPIO==0.5.4
Remove: numpy==1.8.0
Remove: pifacecommon==4.0.0
Remove: pifacedigitalio==3.0.4
Remove: pygame==1.9.1release

8: Install all requirements via pip
sudo pip install -r jasper/client/requirements.txt

I managed to get pocketsphinx working. You need to install it by hand (see http://jasperproject.github.io/documentation/software/#installing-sphinx). Some problems I had:

• the new XCode is strict with its flags and fails. To fix use "ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future " (note: sudo goes in front of ARCHFLAGS)
• I didnt have cython installed
• I initially forgot to run setup.py in the python sub-dir (note: there are some test files in there as well, so have a basic check if your install worked)

[qpaulson]

Thanks!!.. I was actually about to do the same thing :)
I'll continue the quest. :)

[the01]

For those following the steps, the next problem (for me) shows up when building openfst.."'tr1/unordered_map' file not found"
to fix this add 'CXX="clang++ -std=c++11 -stdlib=libstdc++"' to the ./configure flags
see (openfst.org is not working for me right now, so it is a chached version from google) http://webcache.googleusercontent.com/search?q=cache:SIfDTkcDgX0J:www.openfst.org/twiki/bin/view/Forum/FstForum+&cd=1&hl=de&ct=clnk&gl=at&client=firefox-a

[qpaulson]

@the01 Did you do anything special to link pocketsphinx to the OSX python libs? I've followed the instructions, its "installed" according to sudo make install, but when i run jasper it still says the module is not found..?

[the01]

@qpaulson did you run python setup.py install in pocketsphinx-0.8/python/ ?

also I am now stuck at m2m-aligner..I cant seem to get it to install

[the01]

when installing mitlm:

• you need to apply sudo ./configure CXX="clang++ -std=c++11 -stdlib=libstdc++" again
• in src/NgramModel.cpp line 325 change
  assert(prob <= std::pow(10, -99));
  to
  assert(prob <= std::pow(10.0, -99));

[vicramon]

Could anyone who gets this working please post detailed steps?

I was able to compile pocketsphinx, but I get "Failed to open audio device" whenever I run pocketsphinx_continuous.

[qpaulson]

@the01 Ah!.. that did it.. thnx Now onto the next hurdle..

@vicramon Based on the docs, I think we need to install Portaudio. or write an audio backend for OSX.. I'll play with Portaudio i guess. :)

[charliermarsh]

This is a good idea, but one that we haven't really explored. Would be happy to add instructions to the docs if you do get it working!

I got this working this weekend on my MacBookPro (OS X 10.7.5) by following the steps posted by @qpaulson and @the01 with a few more minor tweaks. Here are the steps I took. If there is interest, I can send a pull request to add this to the Docs.

Summary:

1. Installed the dependencies as described by @qpaulson. I wish I had been documenting my approach at this point, because I know I deviated slightly by installing a few of the dependencies through pip rather than relying on Homebrew. I did not make any modifications to the requirements.txt.
2. Installed PocketSphinx by hand as described here
3. Installed other binaries by hand as described here
   * The m2m-aligner Makefile needs to be modified. The gcc_s library isn't available on Darwin systems. Change:

   INLIBS=-lgcc_s -lpthread -lc -lm

   to

   INLIBS=-lpthread -lc -lm

   
   * As pointed out by @the01, mitlm needs a one line code change in src/NgramModel.cpp, line 325. Change

   assert(prob <= std::pow(10, -99));

   to

   assert(prob <= std::pow(10.0, -99));

4. Rather than getting the espeak and aplay utilities installed, I took a shortcut and modified the source in mic.py to use the OS X built-in say command.
5. I made a couple of minor modifications to the boot scripts. Since I'm on my personal laptop, I did not duplicate the expected directory structure on the RPi. My directory structure looks like this:

* jasper-client (root of the Git repo)
    * boot...
    * client...
    * README.md
* jasper-home (root directory, contains the required binaries)
    * m2m-aligner-1.2
    * mitlm-0.4.1
    * openfst-1.3.4
    * phonetisaurus
    * pocketsphinx-0.8
    * sphinxbase-0.8

In jasper-client/boot/boot.sh, I modified the script to export HOME=jasper-home.
I also modified the first line of jasper-client/client/start.sh. The script cd's to the client directory, which it expectes to be at

/home/pi/jasper/client/

I simply updated the first line to cd to the

jasper-client/client

directory which contains the required binaries.

I know this isn't the ideal way of doing this, but it got me up and running. I wrote several modules and I've got Jasper checking my bus schedule and starting Netflix playback for me using Selenium WebDriver.

I'd be interested to get the authors' take on porting Jasper to OS X. Is the intent to keep the codebase completely platform independent, or could we factor out modules that may differ between the RPi and other platforms and select a platform-specific implementation at runtime? (e.g., an implementation of Mic using say for OS X vs. the espeak implementation for the RPi.)

[qpaulson]

This is fantastic!!

I would definitely support making Jasper more Platform agnostic!..
On OSX it could potentially just use Google TTS and STT this may simplify
it a lot as well..

Also, some of the packages are not for the core software, but for the
modules.. Perhaps someone could document which packages are for which
modules.. Then we could just not use the ones we dont want to deal with or
that are not platform agnostic.

Thanks for drudging through this!

I'm following the series of steps here from @qpaulson, @the01 and @astahlman, and now I'm stuck at:

File "sphinxbase.pxd", line 150, in init pocketsphinx (pocketsphinx.c:7935)
ValueError: PyCapsule_GetPointer called with invalid PyCapsule object

It seems to have something to do with Cython. I Cython installed, but I'm not sure what else I need to do. Any ideas here?

[fotiDim]

I would be very much interested in running on iOS as well. +1 for multi-platform approach.
