Error in example as coded in http://elm.readthedocs.io/en/latest/usage.html

[brunialti]

No errors occours until the following statement (the loaded data matches the data set contained in the file):
elmk.search_param(data, cv="kfold", of="accuracy", eval=10)

I get the following error:

`##### Start search #####

Anybody have any solution of this problem ?

I have the same problem, anyone could fix this issue?

If you found an error while using ELMKernel.search_param() or ELMRandom.search_param(), probably is because pip installed an outdated version of optunity (currently their pip package and github are not synced).

To fix it, do:
`
$ sudo pip install -d . elm

$ tar -xf elm*.tar.gz

$ cd elm*

$ sudo pip install -r requirements.txt`

Conversely, you could also install Optunity directly from their Github, using:

sudo pip install git+git://github.com/claesenm/optunity

This will fetch the latest version of Optunity right from their repo and leave everything else intact.

"Successfully installed Optunity-1.1.1"
but the problem still the same!
how to resolve it definitively?

Could you try again ?

I just updated all libraries to their last versions, i got it working fine.
The only problem is some warinings from 'deap'.
