problem in search_param function

[Abdou24MR]

i tried thies example:

`import elm

data = elm.read("C:/Users/abdel/Downloads/elmdevel/tests/data/iris.data")

elmk = elm.ELMKernel()

elmk.search_param(data, cv="kfold", of="accuracy", eval=10)

tr_set, te_set = elm.split_sets(data, training_percent=.8, perm=True)

tr_result = elmk.train(tr_set)
te_result = elmk.test(te_set)

print(te_result.get_accuracy)`

and i have this prolem:

C:\Users\abdel\PycharmProjects\Test1\venv\lib\site-packages\deap\tools_hypervolume\pyhv.py:33: ImportWarning: Falling back to the python version of hypervolume module. Expect this to be very slow.
"module. Expect this to be very slow.", ImportWarning)

Could you try again ?

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