Run ruby-pocketsphinx-server error #8

Closed dakshinai closed 10 years ago

/usr/local/lib/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- md5 (LoadError)

Is there a way to fix this error?

dakshinai commented 10 years ago

I changed the line in server.rb to require 'digest/md5'. I see a new error

Most probably the pocketsphinx GStreamer plugin is not found. Have you compiled it? To test, invoke

gst-inspect-0.10 pocketsphinx

If the result is "No such element..", and you have compiled it, it is most likely just not found. To make it findable, set the GST_PLUGIN_PATH environment variable to the path where the plugin is located. On my machine:

export GST_PLUGIN_PATH=/usr/local/lib

Now, try again with gst-inspect-0.10

dakshinai commented 10 years ago

Thank you.

I have set all of these environmental variables to /usr/local/lib export GST_PLUGIN_PATH=/usr/local/lib export GST_PLUGIN_SYSTEM_PATH=/usr/local/lib export GST_PLUGIN_SYSTEM_PATH_1_0=/usr/local/lib export LD_LIBRARY_PATH=/usr/local/lib

gst-inspect-0.10 pocketsphinx works but gst-inspect-1.0 pocketsphinx does not work

@asr = Gst::ElementFactory.make "pocketsphinx", "asr" returns null

gst-inspect-1.0 libgstpocketsphinx.la Could not load plugin file: File "libgstpocketsphinx.la" appears to be a GStreamer plugin, but it failed to initialize

From these, I'm guessing the server script is using gstreamer1.0. Could you help?

alumae commented 10 years ago

It requires gstreamer-0.10. I think it would not be too hard to make the ruby program handle gstreamer-1.0, but the pocketsphinx GStreamer plugin is written for 0.10 and it's not totally trivial to port to 1.0.

Anyway, GStreamer 0.10 and 1.0 can happily co-exist on he same machine. If you cannot gst-inspect-0.10 the libgstpocketsphinx.so file, then something is probably wrong with you GStreamer setup.

dakshinai commented 10 years ago

Thank you.

As you said all the required plugins are identified by gstreamer-0.10, including pocketsphinx, as I see from these statements.

gst-inspect-0.10 libgstpocketsphinx.la Plugin Details: Name: pocketsphinx Description: PocketSphinx plugin Filename: libgstpocketsphinx.la Version: 0.8 License: BSD Source module: pocketsphinx Binary package: PocketSphinx Origin URL: http://cmusphinx.sourceforge.net/

Also gst-inspect-0.10 pocketsphinx works.

To reconfirm, do you suggest that gst-inspect-0.10 libgstpocketsphinx.so should also work? I'm new to gstreamer and I believe I have done extensive search for this issue with no luck. Could you give me some pointers please?

Thanks in advance.

alumae commented 10 years ago

If gst-inspect-0.10 pocketsphinx works then it should also work from Ruby. Do you still get the same error as described in the initial comment?

You wrote that you now have problems with the filesink plugin? Make sure that the packages gstreamer0.10-plugins-base, gstreamer0.10-plugins-good and gstreamer0.10-plugins-bad are installed.

dakshinai commented 10 years ago

Hello,

I have all these gstreamer0.10-plugins-base, gstreamer0.10-plugins-good and gstreamer0.10-plugins-bad installed. I had reset GST_PLUGIN_SYSTEM_PATH, which lead to filesink not being found. I do not have that issue anymore.

The only problems I'm left with is gst-inspect-0.10 libgstpocketsphinx.so and the server program do not work

But gst-inspect-0.10 pocketsphinx and gst-inspect-0.10 libgstpocketsphinx.la work and apt-get install gstreamer-0.10* is up to date.

The ubuntu system I'm using is a fresh install. Please advice if I can do any code tweaks particular for my case or is there any system check that can help me identify the the issue I'm facing.

dakshinai commented 10 years ago

Hello,

I tried an alternate line @asr = Gst::ElementFactory.find("pocketsphinx").create("asr") instead of @asr = Gst::ElementFactory.make "pocketsphinx", "asr"

find returns nill object though gst-inspect-0.10 works. Could you please help.

Is there a specific ruby, ruby-gems and ruby-gstreamer version I should use?

alumae commented 10 years ago

I managed to reproduce your error with Ruby 1.9.1 (I had Ruby 1.8 before and hadn't upgraded for a long time). I'm investigating it.

alumae commented 10 years ago

It seems that the Ruby 1.9.1 Gstreamer bindings use Gstreamer 1.0 and I see no way to change it. Unfortunately the Pocketsphinx Gstreamer plugin is for Gstreamer 0.10.

So, it seems that currently the only way is to use Ruby 1.8 which is of course a shame as its not even available from the official repositories for recent Linux distributions.

To fix this, PocketSphinx GStreamer plugin must be ported to 1.0.

dakshinai commented 10 years ago

Thank you. I was trying to install ruby1.8 with rvm and I did. However I'm yet unable to install libgst-ruby1.8, as there are too many dependencies for which I'm unable to get a source.

Could you tell me how easy it is and the steps to port the PocketSphinx GStreamer plugin to 1.0?

alumae commented 10 years ago

Porting to Gstreamer 1.0 involves getting to know GStreamer and Pocketsphinx plugin internals, learning the changes from 0.10 to 1.0 ( http://cgit.freedesktop.org/gstreamer/gstreamer/tree/docs/random/porting-to-1.0.txt), implementing the new plugin and figuring out what to do with the two versions (I would vote for just replacing the 0.10 plugin with the new one in the SVN trunk).

But as you probably know, I'm not the author or Pocketsphinx GStreamer plugin, so you should probably ask the CMU SPhinx people about it.

Hello,

I tried all the steps on an older Ubuntu distribution (10.04 LTS) and I was able run the server with ruby-1.8.

I'm seeing a new error

Setting hmm to models/est16k.cd_cont_3000-mapadapt... ERROR: "pocketsphinx.c", line 134: Failed to find mdef file inside the model folder specified with -hmm 'models/est16k.cd_cont_3000-mapadapt' INFO: feat.c(713): Initializing feature stream to type: '1s_c_d_dd', ceplen=13, CMN='prior', VARNORM='no', AGC='none' INFO: cmn.c(142): mean[0]= 12.00, mean[1..12]= 0.0 ERROR: "acmod.c", line 87: Folder 'models/est16k.cd_cont_3000-mapadapt' does not contain acoustic model definition 'mdef'

I do not see a models directory in the server code base? Could you help clarify this?

alumae commented 10 years ago

Contrary to the documentation, the the conf.yaml file was using Estonian models. I updated the configuration to use English models that Sphinx automatically installs (see conf.yaml and modify accroding to your needs). I also updated the main README.

dakshinai commented 10 years ago

Thank you!! I'm now able to run the server successfully.

Few notes if you can validate at your end:

  1. I commented out lines that worked on property "cmn_mean", as this does not exist in the latest build of pocketsphinx.
  2. The pocketsphinx patch "patch -p0 -i ps_gst.patch" rejects some changes and also makes pocketsphinx to build with errros.
  3. I had to "gem install rdoc" before doing a "gem install sinatra"

Thank you again for patiently and consistently helping me through to run the server.

dakshinai commented 10 years ago

Hello!

I have a question. Does the server app support remote connections? curl -T $(POCKETSPHINX_DIR)/test/data/wsj/n800_440c0207.wav -H "Content-Type: audio/x-wav" "http://serverip:8080/recognize" I tried printing on a GET request and it did work.

However the content length on a PUT request is less and no response is returned. I see 504 error. Could you check at your end once?

alumae commented 10 years ago

What do you mean by remote connection? Client and server on different machines? Yes, this is supported (actually this the point of this software). We use it like that all the time.

I don't understand the rest of your comment. Can you give me the output of the curl command and what the server prints to sysout/syserr as the result?

dakshinai commented 10 years ago

I'm trying to send a audio file from windows to the ubuntu server using a http put request.

Instead of localhost, I tried a wget/curl/fiddler http put request to http://serverip:8080/recognize. I got a timeout 504 error. In fiddler I saw that server gave a empty response. (The remote request is identical to local request except for server ip address)

I ensured that telnet to the serverip on port 8080 worked.

In the server debug I logged the request content length. The remote request had a size lesser than a successful localhost request (18k compared to 100k). I'm guessing this is the padding length.

alumae commented 10 years ago

The timeout error might indicate that there is a firewall between your client and server.

As I said before, please give me the output of curl (with -v (verbose option)) and server. For example, in my system:

Client:

What does the server print out when you make a remote request?

dakshinai commented 10 years ago

This is what I see

This is the log I had added I, [2014-06-18T10:47:40.129278 #2769] INFO -- : Length:18786

The length is 1/10 of a successful request.

You are using some proxy between your client and server? What kind of proxy? The server-client protocol uses HTTP chunked transfer encoding -- maybe it's not supported by the proxy?

dakshinai commented 10 years ago

Hello, I tried a curl between two ubuntu machines. Both had no firewall and I disabled proxy but I still see the timeouts (same error). I was able to telnet from machine 1 to server.

Any idea?

alumae commented 10 years ago

Let me get it straight: the exact same audio file is processed correctly when sent from the local machine but causes a timeout when sent from a remote machine? If this is the case then I'm afraid I cannot help. There isn't any code in the server that could cause this. This must be caused by some other factors. Remotely sent files are processed just fine on my setups.

dakshinai commented 10 years ago

Hello,

These are my findings. I put a stub debug print for HTTP PUT/GET/POST in server.rb. All the remote requests were handled with a 200OK. Also I added support for text/plain and tried a debug print on the server to see request body. The text file went intact. Could you give me some pointers to troubleshoot further? It will be of great help.

dakshinai commented 10 years ago

Hello,

I tried with a small audio file and it went through the remote request. The server works for me now for all files. Thanks so much for your guidance :)

alumae commented 10 years ago

Thanks a lot for your patience!

FYI, pocketsphinx has been just ported to gstreamer 1.0

alumae commented 9 years ago

OK, will port soon.
