Sacredboard fails when started without parameters.

I want to try out the develop branch to test the metrics API + plots with sacred 0.7b2. However I do get the following error:

I tried dropping the sacred database in mongodb and ran sacredboard on an empty database but I got the same error, as well as after doing some new sacred experiments again.

Any idea where I can look?

Versions: pymongo==3.4.0 sacred==0.7b2 sacredboard==0.2

Hi,

it looks like a Sacredboard issue. Could you perhaps tell me

• the command you run sacredboard with
• when exactly the error you mentioned is occurring? (Upon startup / when doing something in the application?)

Thank you.

Hi,

I just run "sacredboard" which also automatically opens my browse and displays an ajax error. So I don't know if the error occurs before or after loading the website.

However, I just found the problem. I missed the small piece of information right at the start of sacredboard's console output: "Must specify either a mongodb instance or a path to a file storage."

So I ran sacredboard -m sacred which works! It seems sacredboard doesn't use the default value anymore.

[chovanecm]

Great that you found the reason. Removing the default option was not my intention, thank you for noticing it.

I changed it to print the error message and exit. Please use sacredboard -m sacred for now.
