Description
When setting up the training cluster following step by step guidelines with Spark runtime 3.7 running databricks 6.4 (includes Apache Spark 2.4.5, Scala 2.11)
get the following error
File "/databricks/python/lib/python3.7/site-packages/IPython/nbconvert/postprocessors/serve.py", line 31, in ProxyHandler
@web.asynchronous
AttributeError: module 'tornado.web' has no attribute 'asynchronous'
It seems we need to reinstall nbconvert and tornado to an older version?
