Hi - where can I find an example of how to do real-time, time series plotting - as shown in your blog ? It's fantastic - me want ! :)
From https://github.com/RoboStack/jupyter-ros
typed in
pip install jupyter bqplot pyyaml ipywidgets
jupyter nbextension enable --py --sys-prefix ipywidgets
Results in:
KeyError: 'The Python module ipywidgets is not a valid nbextension, it is missing the `_jupyter_nbextension_paths()` method.'
Happens both on Windoze 10 install and Debian 10 install.
I am still trying to figure out the threading model of this approach.
Logging an issue to describe details of errors to answer question from Gitter thread. I tried to run the notebook named - Ros2 Pub_Sub_Communication.ipynb from pre-release https://github.com/RoboStack/jupyter-ros/tree/v0.6.0a0/notebooks and got following errors. It may be some issue with the way I installed the package and extensions. I tried to follow instructions from here to install from source.
I have an env named ros_env which has ROS2 humble installation with full desktop version of humble installed and it works correctly. I also tried to set ROS_DISTRO=humble in the terminal within jupyter-labs to see if it will make any difference but it didn't help.
I also have another env named ros2_foxy where ROS2 foxy is installed and main computer where ROS2 foxy is installed as well with ROS_DISTRO=foxy for main computer. I can see that in the error description it is still trying to look in the paths under /opt/ros/foxy even though I am running in humble so may be that's the main issue somehow.
Please suggest any options as I'm willing to try to get it to work with ROS2 in jypyter-labs. It will be a big help for community overall if I can document how to get it working.
I did make a change in the ~/mambaforge/envs/ros_env/jupyter-ros-0.6.0a0/jupyros/init.py file to change the ros version to 2 and name to humble like this, I thought this was necessary to use ROS2 but I could be wrong:
from ._version import __version__
import os
try:
ros_version = os.environ['ROS_VERSION']
ros_distro = os.environ['ROS_DISTRO']
except KeyError:
# print('No ROS environment detected.')
# print('Defaulting to ROS noetic.')
ros_version = '2'
ros_distro = 'humble'
While running following block of code in jupyter-labs:
## Relative pathing to the Jupyros module (jupyter-ros/jupyros), due to difficulty with with development install
## Remove at PR is Dev Install successful

Two main errors received - one saying jupyros not found and the other with context problem related to rp.init()
The rclpy package is not found in your $PYTHONPATH. Subscribe and publish are not going to work.
Do you need to activate your ros2 environment?

Hi,
I am glad development continues - thanks so much. We had built a docker container after we found out what versions of extensions and python packages works with jupy ros. After the update on th e 15th it is broken again. Currently we fixed it by forcing to use jupyros 0.12a0.
Could you please provide an enviroment.yml with versions of python packages and widget extensions used, when you update things?
Thanks a lot
regards
Riko
Can more then one ros jupyter session be stated in different tabs one for each node? Like in a launch file.
Is there a way to use directly the pose from AMCL (PoseWithCovarianceStamped) in the ros3d.Pose() widget? Right now I have to create another publisher to publish a PoseStamped message using this code :
pose_msg = Pose()
def amcl_callback(msg):
global pose_msg
pose_msg = msg.pose.pose
pose = PoseStamped()
pose.header.seq = 1
pose.header.stamp = rospy.Time.now()
pose.header.frame_id = "map"
pose.pose.position.x = pose_msg.position.x
pose.pose.position.y = pose_msg.position.y
pose.pose.position.z = 0.0
pose.pose.orientation.x = pose_msg.orientation.x
pose.pose.orientation.y = pose_msg.orientation.y
pose.pose.orientation.z = pose_msg.orientation.z
pose.pose.orientation.w = pose_msg.orientation.w
pose_pub.publish(pose)
Please consider adding license information to your repo and files
Please consider editing the README.md development installation instructions to
git clone https://github.com/RoboStack/jupyter-ros.git
Instead of
git clone https://github.com/wolfv/jupyter-ros.git
(or adding some kind of warning since both repositories are popular)
It took me too much time to figure out why the newer features in the RoboStack master branch where not working.
Thanks for this great project!
when I run "jupyter nbextension install --py --symlink --sys-prefix jupyros" , it breaks down for the following error. My environment is python 3.9 and it seems python3.x do not support the Unicode function. Hope to get some clues!!!!
File "/jupyter-ros/jupyros/ros1/ros3d.py", line 73, in ROSConnection
url = Unicode(os.environ.get("JUPYROS_WEBSOCKET_URL", "ws://Z9d2n4:9090")).tag(sync=True)
NameError: name 'Unicode' is not defined
I got error when I ran the code
"jupyter labextension install jupyter-ros "
Error executing Jupyter command 'labextension': [Errno 'jupyter-labextension' not found] 2
I was runing from jupyros import ros3d
and get error "ImportError: cannot import name 'ros3d' from 'jupyros'"
ImportError Traceback (most recent call last)

----> 1 from jupyros import ros3d

ImportError: cannot import name 'ros3d' from 'jupyros' (/Users/chengtszyin/Desktop/new_ws/jupyter-ros/jupyros/init.py)
Please help. THANK YOU
I got this error and solved it by running the command below, it would be helpful if you add this to the documentation, to remind the users to enable the extension
jupyter nbextension enable --py --sys-prefix widgetsnbextension
This looks really promising!
However instead of accepting live data, IMHO a more common use case for jupyter is to analyze recorded data. So in the ROS context that usually means bag files.
It would be great to have good support for bag files.
https://github.com/cruise-automation/webviz could be useful here as well.

any ideas what I am missing? I'd really like to give it a try, but unfortunately there is this issue in my environment, and I really do not have a glue about how to proceed.
For completeness, here is the command I used to create a fresh environment:
micromamba create -n ros_jupyter python=3.9 jupyter-ros -c robostack -c conda-forge --no-channel-priority --override-channels
I would like to import custom ROS message types definitions from another ROS module lying in the same catkin workspace as the jupyter notebook. Anyone knows how to do that?
Actually it would be great to run the jupyter-ros notebook as catkin module, to realize a live monitoring node of the stack. Any ideas?
Thanks a lot.
Riko
Hello and thank you for this great project!
I'm trying to package it in a ROS Docker image
I have an error when installing (following the .README instructions)
Would anybody here have an idea of what might be the problem?
Thank you so much.

does not have any display capabilities.
I am trying to get the package to work with Jupyter Lab. However the UI widget just for pub and subscribe don't seem to work. Do I install them differently for lab?

Hi, I've tried running python setup.py install --user
and noticed that some paths are broken.
The path jupyros/static/... isn't in the project so python will throw an error (Lines 69-70, 135-137).
I'd love to install the most recent library (without relying on pip), so please let me know if this can be resolved or if there's a quick fix.
Thank you
The extension (v0.7.0) is currently not compatible with JupyterLab>=4.0 and Notebook>=7.0
after setting up everything, you still can't use the action_client widget in jupyter. It throws key doesnt exist exceptions.
What is the right course of action for accessing custom messages from other ROS packages? I was trying to see if there was something in the examples, but I couldn't find anything.

Hi, great job on this. I'm excited to see where it goes.
Just some feedback... In order to get the widgets to render in Jupyter Notebook, I had to install ipywidgets.
I did so by executing the following:

When I am writing or debugging a node in Jupyter Notebook + Jupyter Ros, I often need to run the edited version. I've been restarting the kernel in Jupyter as a way to try to get it to run the edited node, but I am not sure that works or is reliable. I've also tried killing roscore and restarting it. I am not sure yet what works and what doesn't. What's the recommended way to do this?
When I use this line to plot only the x and y values, I get x,y, and z values plotted
jr.live_plot("/my/posetopic:x:y", geometry_msgs.Pose)
It works as expected if I use
!rqt_plot /my/posetopic/x /posetopic/y
Thanks!

Well...
Don't know what to do:
I have my roscore working fine, with rviz I can see my /scan => No issues
using jupyros is another story:
1st code (proposed in the documentation) working fine:
import jupyros as jr
import rospy
from std_msgs.msg import String
rospy.init_node('jupyter_node')
jr.subscribe('/sometopic', String, lambda msg: print(msg))
2nd code just render a grid without scan, no error message, no warning, nothing.
How to debug???
Here is my code:
import rospy
import jupyros as jr
from jupyros import ros3d
from ipywidgets import Layout
import os
v = ros3d.Viewer()
v.layout=Layout(border="3px solid red",width="800px",height="400px")
rc = ros3d.ROSConnection(url="ws://localhost:9090")
g = ros3d.GridModel()
tf_client = ros3d.TFClient(ros=rc, fixed_frame='/base_link')
laser_view = ros3d.LaserScan(topic="/scan", ros=rc, tf_client=tf_client)
#urdf = ros3d.URDFModel(ros=rc, tf_client=tf_client, path=os.environ.get('JUPYROS_ASSETS_URL', 'http://localhost:3000'))
v.objects = [g, laser_view]
v
Is there a way to include images from the robot's camera in the ros3D visualisation? Is it a feature that is planned? The only way I found to do it is to use a threading to update the images from the camera inside a grid, but the results make the video feed delayed by a couple seconds (not delayed without the ros3D object). Here is the code I am using to create a user interface :
from ipywidgets import HBox, Box, Layout, GridspecLayout
from jupyros import ros3d
import ipywidgets as widgets
import threading
import time
v = ros3d.Viewer()
rc = ros3d.ROSConnection(url="ws://localhost:9090")
tf_client = ros3d.TFClient(ros=rc, fixed_frame='/map')
g = ros3d.GridModel()
laser_view = ros3d.LaserScan(topic="/scan", ros=rc, tf_client=tf_client)
map_view = ros3d.OccupancyGrid(topic="/map", ros=rc, tf_client=tf_client)
pose_view = ros3d.Pose(topic="/mobile_manip/pose", ros=rc, tf_client=tf_client)
v.objects = [laser_view, map_view, pose_view]
v.layout = Layout(border="3px solid black", width="700px", height="600px")
image = widgets.Image(
value=cam_msg.data,
format="png",
height="120%",
width="200%")
btn_up = widgets.Button(icon='arrow-up')
btn_left = widgets.Button(icon='arrow-left')
btn_down = widgets.Button(icon='arrow-down')
btn_right = widgets.Button(icon='arrow-right')
btn_stop = widgets.Button(description='Stop')
def update_plot():
while True:
image.value=cam_msg.data
time.sleep(0.1)
def on_btn_up_clicked(b):
move_robot(0.5,0)
def on_btn_left_clicked(b):
move_robot(0,0.5)
def on_btn_down_clicked(b):
move_robot(-0.5,0)
def on_btn_right_clicked(b):
move_robot(0,-0.5)
def on_btn_stop_clicked(b):
move_robot(0,0)
btn_up.on_click(on_btn_up_clicked)
btn_left.on_click(on_btn_left_clicked)
btn_down.on_click(on_btn_down_clicked)
btn_right.on_click(on_btn_right_clicked)
btn_stop.on_click(on_btn_stop_clicked)
grid = GridspecLayout(8, 8,height='600px')
grid[0:4,0:3] = image
grid[5,1] = btn_up
grid[6,0] = btn_left
grid[6,1] = btn_stop
grid[6,2] = btn_right
grid[7,1] = btn_down
grid[:,4:7] = v
thread = threading.Thread(target=update_plot)
thread.start()
grid
Hi! Thanks for your repo.
When I run
!jupyter nbextension enable --py --sys-prefix jupyros
I get an error. Could anyone help me ?

Hello,
I got this error while tring to create my widget with your example. I checked the source code and the widget_for_msg function doesn't seem to exist. Also could you give me an example of the use of the jupyros.add_widgets function ?
Thank you very much

What's interesting is that roslibpy offers a viable route of working with ROS without having the requirement of running in a ROS environment. Those environments that work with ROS, -well basically Ubuntu linux- are quite a small subset from those environments that run python well.
I think a powerful use case of this project is having a ROS docker running somewhere, and using jupyter-ros
to interface it, without having to create the actual ROS environment.
Might be worth looking into it, or to decide whether a ROS env is a requirement or not
I'm getting this error:

Digging in the problem comes from base.IJupyterWidgetRegistry in https://github.com/RoboStack/jupyter-ros/blob/master/js/lib/labplugin.js#L14 not being the same object as the object saved in the serivice map. I think it's because the deduplication step is not doing what it should, when I install with jupyter labextension install jupyter-ros --debug

Hi,
I need to plot several topics at the same window using live_plot() function, is that possible?
Thanks,
Mohammad
I dont know how you determine the ranges for the generated ui for jr.publish. But if you are publishing Twist, the ranges are 0.0 -> I think 100 or something. It would be nice if you changed that to -10 -> +10. When the max is 100 the slider is too sensitive for normal cases.
When starting a jupyter notebook (or jupyter lab) I get the error:
libgcc_s.so.1 must be installed for pthread_cancel to work
Aborted (core dumped)
This only happens after I install jupyter-ros. Any ideas?
I'm using Python 3.7 in a conda 4.8.3 environment.
commands to reproduce:
pip3 install jupyros
jupyter nbextension enable --py --sys-prefix jupyros
on version 0.2.0 gave the output:
The rospy package is not found in your $PYTHONPATH. Subscribe and publish are not going to work.
Do you need to activate your ROS environment?
Enabling notebook extension jupyter-ros/extension...
- Validating: OK
now in version 0.2.1 gives the error:
The rospy package is not found in your $PYTHONPATH. Subscribe and publish are not going to work.
Do you need to activate your ROS environment?

Hi,
When I tried to publish string message using Start button with rate = 10, I noticed from the terminal when I ran rostopic hz the frequency was increasing constantly with low increases from 0.1 hz to 9.8 hz.
How can I avoid this issue?
