2016-09-05 23:26:47 -0600 asked a question Getting Parse Errors for alice chatbot with ros

Hi,

I want to create a chatbot application and I came across this package for ROS. I cloned the repo into my workspace and have managed to get it working. There were a few changes that were needed in the launch files. Now, robot.launch files fires up the three nodes. However, i am getting the following list of errors:

/home/<username>/<workspace>/src/chatbot/scripts/ai.py:18: SyntaxWarning: The publisher should be created with an explicit keyword argument 'queue_size'. Please see http://wiki.ros.org/rospy/Overview/Publishers%20and%20Subscribers for more information.

From this point both the terminals (with web.launch and robot.launch) are waiting for something. What would be the next step? Also how do I get rid of this parse errors?

Any help would be appreciated :)

2016-08-26 04:54:43 -0600 answered a question How do we set the parameters for any existing package

I searched a bit more and found this website. The guy walks through a very similar tutorial. However, his package seems to have a demo folder which explains a lot. He has simple launch files within which the params lm and dic are specified. I am still curious in finding out ways to edit parameters on the go and using the yaml option.

2016-08-25 22:53:16 -0600 asked a question How do we set the parameters for any existing package

Hi,

I am working with the pocketsphinx package. I have managed to download the requied lm and dic files for the same using Sphinx Knowledge Base Tool. However, i am unable to set the path in the paramaeters. I tried looking at the tutorial for rosparam. Since, I recetly started using ROS, I still feel fairly confused. So far, I have created a dump.yaml as follows:

dic: /home/fday562/Downloads/TAR5770/5770.dic
lm: /home/fday562/Downloads/TAR5770/5770.lm
recognizer: {}
rosdistro: 'indigo

  '
roslaunch:
  uris: {host_en_330372__37414: 'http://en-330372:37414/'}
rosversion: '1.11.20

  '
run_id: 0be57b0a-6b36-11e6-9620-3417ebab4615

I have saved this file in ~/<myworkspace>/src/pocketsphiinx/.

However, upon running rosrun pocketsphinx recognizer.py I always get a warning saying:

<MyWorkspace>/src/pocketsphinx/nodes/recognizer.py:68: SyntaxWarning: The publisher should be created with an explicit keyword argument 'queue_size'. Please see http://wiki.ros.org/rospy/Overview/Publishers%20and%20Subscribers for more information.
  self.pub = rospy.Publisher('~output', String)
[WARN] [WallTime: 1472182172.183704] lm and dic parameters need to be set to start recognizer.

I have spent alot of time trying to change the location of the file dump.yaml but all in vain. Is there any step that i am missing?

I am new to ROS and have been using the pocketsphinx package that you have mentioned above. I have managed to install it and also get a sample lm and dic file through the Sphinx Knowledge Base Tool. However, I am unable to set the path to it.Pls help

Did you find a solution. If yes could you please update this thread? I am facing the exact same issue. I am using Ubuntu 10.04 and Indigo

Thanks! Downgrading pip worked for me. Was facing the same issue with ROS Indigo on Mac OS X El Capitan

2016-08-22 07:50:32 -0600 answered a question Unable to resolve dependencies while ROS Install on Mac

I tried Mike Purvis's solution and it works! Thanks for the tip spmaniato! It takes a long time though. Just a tip for all those who might need help in the future. Packages like pyqt, sip may throw ImportError during compilation. A simple brew unlink <package that throws ImportError> && brew link <same package> works like magic.

2016-08-20 23:12:15 -0600 asked a question Unable to resolve dependencies while ROS Install on Mac

Hi,

I am trying to install ROS Indigo on Mac OS X El Capitan and am following this tutorial. However, along the tutorial I am getting suck at the step 2.1.2 wherein I need to run the following command:

$ rosdep install --from-paths src --ignore-src --rosdistro indigo -y

Upon doing so, I get the following error:

$ rosdep install --from-paths src --ignore-src --rosdistro=indigo -y
executing command [sudo -H pip install -U urlgrabber]

I tried looking for help, but am not able to get through. Does anyone have a clue why?

Thanks :)

2016-08-19 03:22:51 -0600 asked a question Help with setting up Kinect

Hi,

I am new to the ROS Community and am trying to connect a Kinect camera with ROS for my current project. I am using Ubuntu 14.04 and the ROS indigo distribution.

So far, I have followed the tutorial http://wiki.ros.org/Robots/evarobot/T... . However towards the end of the tutorial, after the step roslaunch openni_launch openni.launch, I get a the following warnings:

----------
[ WARN] [1471581084.378448573]: Camera calibration file /home/fday562/.ros/camera_info/rgb_B00364629578138B.yaml not found.

[ WARN] [1471581084.378520480]: Using default parameters for IR camera calibration.

Everything else works fine. Earlier I was trying to use usb_cam and it threw similar warnings. Any idea whats this about? Any help is appreciated.

Thanks :)
