Error on result page

[rcoenen]

Hi, ok I finally managed to get Japonicus complete a full run.
Just for the purpose to test a quick full run, I modified various settings to get the process to speed up:

• 10 EPOCHS instead of 3000 (default)
• 10 DeltaDays instead of 90 (default)
• 20 POP_SIZE instead of 50 (default)
• 10 dataset_span instead of 0 (default)
• 10 eval_dataset_span instead of 0 (default)

At the end of the run the terminal showed the settings that I could use on Gekko.
However, when I went to the Japonicus web interface and clicked on the "View Results" tab, the webpage remained empty and I got this in the Terminal:

ERROR:flask.app:Exception on /_dash-update-component [POST]

Update: half-assed fix

in /home/ubuntu/gekko/japonicus/promoterz/webServer/layout.py line 87
changed
return [html.P(str(r[0]) + '\n' + r) for r in app.resultParameters]
into
return [html.P(str(r[0]) + '\n' + str(r) ) for r in app.resultParameters]

Now the web-UI results tab shows a slightly awkwardly formatted
-3.729552660176836 (-3.729552660176836, 'interval = 14.672\n\n[thresholds]\nhigh = 51.94\nlow = 35.22\npersistence = 1.09\n')

but at least it does not throw any errors in the terminal

NOTE: I am running Gekko + Japonicus under a 'screen' session on EC2, so the error thrown in the terminal when clicking the "View Results" tab in the web UI displaces the GA results in the Terminal... it is really hard to scroll back and see the final results! It's therefore really important to me that the Web UI functions properly. Imagine I'd be running a serious 3000 epoch session and after 72hrs I get the results... only to be washed away with some python error!

I have the same error, let's see about a fix.

Hey @rcoenen

Here is a good fix

As you mentioned, it was solved by changing line 87 in ./promoterz/webServer/layout.py with this code. This will make it print nicely in a textarea so you can directly copy and paste it from there :-)

def getResults(app):
    return [html.Textarea(str(r[0]) + '\n' + str(r[1]), style={'width': '525', 'height': '550'}) for r in app.resultParameters]

I made a PR
