Unsupported class file major version 58

[ierezell]

Hi,
First thanks a lot for this nice work !
It seems that you used spark and the java version on tensorflow to accomplish that right (with python as wrapper)?

I tried to install the nlu package on my python 3.8 which for now doesn't work (and it's okay #11 ).
So I created a virtual environement with python 3.7.

Launching ipython, import nlu that works.

However when I try to do as the doc : nlu.load('sentiment').predict('Why is NLU is awesome? Because of the sauce!') (In fact just nlu.load('sentiment') is the reason of the crash)

It return an

<class 'pyspark.sql.utils.IllegalArgumentException'>
'Unsupported class file major version 58'

I'm using Archlinux kernel zen 5.9.1 on a new virtual env with only wheel and nlu installed on python 3.7.9

I have java 8 / 11 and 14 installed

Edit :

For those getting the same problem : You need java 8 activated by default (or pyspark configured as so)

For those on archlinux : sudo archlinux-java set java-8-openjdk/jre did the trick (check then with archlinux-java status)

I'm sorry to made a issue for nothing I should have RTFM.

(I still have the apache warning for versions but it's ok and working)
