Metrics in scientific notation are not correctly parsed by default

/kind bug

This is an excerpt of a Log of one Trial: As you can see the Score is still correct in file-metricscollector.go:49 but is then wrongly parsed somewhere:

I1007 08:08:59.928474      73 main.go:136] Score=-7.539458549707136e-05

7.10.2021 10:09:01 W1007 08:09:01.339500      73 file-metricscollector.go:49] Metrics will not have timestamp since Score=-7.539458549707136e-05 doesn't begin with timestamp string

7.10.2021 10:09:01 I1007 08:09:01.348925      73 main.go:397] Metrics reported. :

7.10.2021 10:09:01 metric_logs:<time_stamp:"0001-01-01T00:00:00Z" metric:<name:"Score" value:"-7.539458549707136" > >

Thanks for you comment 😃 I think we should take this ([\w|-]+)\s*=\s*([+-]?\d(\.\d+)?([Ee][+-]?\d+)?)

to cover this case :Score=1.23E99 and Score=+1.23E-99

Perhaps it would make sense to correctly parse scientifc notation with the default regexp pattern though?

I think so too. I’ll take this issue

([\w|-]+)\s*=\s*((-?\d+)(\.\d+)?(e(-|\+)?\d+)?) should work
