Cap jupyter-events to <0.5.0 due to jsonschema version conflict

[akchinSTC]

Signed-off-by: Alan Chin akchin@us.ibm.com

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
jupyter-events 0.5.0 requires jsonschema[format-nongpl]>=4.3.0, but you have jsonschema 3.2.0 which is incompatible.

Need to cap jupyter-events due to 0.5.0 requiring jsonschema > 4.x, which causes conflicts with KFP dependency

Did this actually help you resolve the issue?

jupyter-events <0.5.0 installs because it doesn't have a version floor for jsonschema in its dependencies, but it (or jupyter lab as a whole) actually doesn't run with jsonschema<4 anyway - at least for me...
