Hi,
I am running a bokeh server and getting a message in the console saying:
'Unhandled Error reply to 5221166D6FDE848408DB6B4BB403F796A: ValueError(‘The truth value of an array with more than one element is ambiguous. Use a.any() or a.all())’
I am aware that this is a python error, however, the bokeh app still works as expected and there doesn’t seem to be a way for me to trace the ‘error’ back to a line in the python code.
Any idea why this is happening?
Thanks,
Mike
Can you post the full stack trace? Assuming the problem is coming from your code, the issue is that you can't use a numb array in an implicit boolean context:
In [8]: import numpy as np
In [9]: a = np.array([True, False])
In [10]: if a: pass
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)
<ipython-input-10-65a7b6765dd7> in <module>()
----> 1 if a: pass
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
And the solution is to use a.all() or all(a) as suggested.
Thanks,
Bryan

Hi, yes I was aware that this was the cause of the error but where it came from was a mystery!
Using --log-level debug in bokeh serve the full traceback is as follows:

Hi,
I would say this is possibly two things:
* a usage error (passing an array as a property when it's not appropriate)
* combined with bad handing on the Bokeh side (should catch in validation or give better error)
Is there any way you can identify what line in your code might be triggering this exception in Bokeh? (or share a minimal example?)
Thanks,
Bryan

Hi,
As mateusz noted before I got to it, this actually seems to be a dupe of another issue that was just fixed. There will be a new dev build out later today, if you have a chance to try out you code with it to verify that this week that would be helpful!
Thanks,

Hi,
Can confirm this is fixed in ‘0.12.6rc3’.
Thanks

Hi,
As mateusz noted before I got to it, this actually seems to be a dupe of another issue that was just fixed. There will be a new dev build out later today, if you have a chance to try out you code with it to verify that this week that would be helpful!
Thanks,
Bryan

The issue was related to passing a numpy array to the FixedTicker model. I have created a GH issue https://github.com/bokeh/bokeh/issues/6405.
Thanks,

Hi,
I would say this is possibly two things:
a usage error (passing an array as a property when it’s not appropriate)
combined with bad handing on the Bokeh side (should catch in validation or give better error)
Is there any way you can identify what line in your code might be triggering this exception in Bokeh? (or share a minimal example?)
Thanks,
Bryan

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()I can open an issue on GH unless you know of a related issue.
Thanks again for working tirelessly with the community!

Should add: if the error is coming from Bokeh code, then that’s probably a bug and a GH issue with full information would be appreciated.Thanks,

Hi,
I am running a bokeh server and getting a message in the console saying:
'Unhandled Error reply to 5221166D6FDE848408DB6B4BB403F796A: ValueError(‘The truth value of an array with more than one element is ambiguous. Use a.any() or a.all())’
I am aware that this is a python error, however, the bokeh app still works as expected and there doesn’t seem to be a way for me to trace the ‘error’ back to a line in the python code.
Any idea why this is happening?
Thanks,
Mike
