OK, so, I removed the reference to 'resize' in the default tools list. Now, it's complaining about nodejs:On 02/27/2018 02:13 AM, Kartik Patel wrote:
Hello Marcus,
During my testing, I think, I set the time.sleep function by try and error. I didn't check for different PC. I will update it after testing it on my too slow AWS may be.
Also, this resize issue is because Bokeh stopped the support of resize feature. If you can, use Bokeh V0.12.6, and tornado v4.4. I have to Port the code to recent Bokeh version.
Thanks for the extensive verifications. I will try to update the basic suggestions this weekend probably.

I can get past this error by setting a longer "time.sleep()" in the generated "main" -- I guess it takes a bit for the server to come up to a state where it can accept connections.On 02/27/2018 12:15 AM, Kartik Patel wrote:
Thanks for the very-prompt response. I know that you're probably very busy.Hello Marcus,
Just for starters, make sure you have v3.7.12 of GNU Radio. In particular, your GR should contain the commit `3c989f9`. Also, make sure you select Bokeh GUI instead of QT GUI in Generate Options field in Options block. For Bokeh GUI we have a different `main()` function template that has necessary procedure to start the server and the stream.
Also, thank you very much for the suggestions about the vector plotter. In addition to the vector plotter, the Histogram plotter and BER curve are also in pipeline. I am too busy with several deadlines and projects. But I will try to incorporate the things as soon as possible (maybe in summer). Sorry for the loong promise!
Let me know if you still have trouble working with the module.
Thanks.

I managed to get to the point of GRC generating the correct startup code, with the "Bokeh GUI". My repo was up-to-date, it's just that I hadn't actually built it. Too many distractions...
But when I got to start now, I get:

/usr/lib/python2.7/site-packages/bokeh/client/session.py: 316: UserWarning:
!!!! PLEASE NOTE !!!!
The use of `session.loop_until_closed` and `push_session` to run Bokeh
application code outside a Bokeh server is **HIGHLY DISCOURAGED** for any real
use.
Running application code outside a Bokeh server with bokeh.client in this way
has (and always will have) several intrinsic drawbacks:
* Fast binary array transport is NOT available! Base64 fallback is much slower
* All network traffic is DOUBLED due to extra hop between client and server
* Server *and* client process must be running at ALL TIMES for callbacks to work
* App code run outside the Bokeh server is NOT SCALABLE behind a load balancer
The bokeh.client API is recommended to use ONLY for testing, or for customizing
individual sessions running in a full Bokeh server, before passing on to viewers.
For information about different ways of running apps in a Bokeh server, see:
