Stack traceback and/or browser JavaScript console output

I am seeing the same issue with Zeppelin 0.90-preview1.

Thanks @mhebrard for reporting this issue, let me take a look at it .

[zjffdu]

One workaround is not using bkzep (At least bokeh 2.x doesn't need bkzep.

[epugh]

@zjffdu thanks for the workaround, I just tested it on the 0.9.0 preview1 release, and your workaround worked! Now I need to learn about BokehJS!

I am also facing this issue, and the work around looks like it relies on an ipython interpreter, but I'm using a pyspark interpreter? I've also tried implementing this fix locally: bokeh/bokeh#9854 (comment) but just get error name 'bundle_for_objs_and_resources' is not defined.

@PeterKnightGE Is it possible for you to use ipyspark which underneath use ipython interpreter. Look at the document here http://zeppelin.apache.org/docs/0.9.0-preview1/interpreter/spark.html#ipyspark-recommended
