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.

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.

Thanks for the very-prompt response. I know that you're probably
very busy.
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:
Traceback (most recent call last):

IOError: Cannot push session document because we failed to

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.
But now:

OK, so, I removed the reference to 'resize' in the default tools list.
Now, it's complaining about nodejs:

/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:
