missing beakerx.button

[0xg0nz0]

With latest code on Jupyter Lab 1.2.9 with the standard labextension (see previous issue) I get the following error when doing a simple "from beakerx import *":

from beakerx import *
from beakerx.object import beakerx

ModuleNotFoundError Traceback (most recent call last) in 2 import pandas as pd 3 ----> 4 from beakerx import * 5 from beakerx.object import beakerx

I tried to copy over button and got a bit further (missing "bottle" and "pyspark" dependencies) but then it breaks again on a pyspark API change:

~/.local/lib/python3.8/site-packages/pyspark/cloudpickle.py in _make_cell_set_template_code() 124 ) 125 else: --> 126 return types.CodeType( 127 co.co_argcount, 128 co.co_kwonlyargcount,

TypeError: an integer is required (got type bytes)

Latter is because I'm on Python 3.8, which PySpark 2.4.5 does not support.
