NSGAII #40

Hi,

I am new to this framework so not sure if there is a problem on my side, but whenever I'm trying to run any of the NSGAII examples I get the following errors:

C:\Users---\PycharmProjects\jMetal\venv\Scripts\python.exe C:/Users/---/PycharmProjects/jMetal/Main.py C:\Users---\PycharmProjects\jMetal\venv\lib\site-packages\dask\config.py:161: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe.

My version of jmetalpy is 0.9.0 and this happens only when I'm running the NSGAII examples.

Thank you in advance for your help.

It seems that there is some problem with Dask. jMetalPy requires dask[complete]==1.0.0. Can you verify which version of Dask is installed on your environment?

Thanks a lot for the quick reply. I had version 1.0. I just updated it to 2.0 and that seemed to solve it.
