Yeah guys, you need to fix the version of all the requirements, I went through so many errors and I am stuck again. Very hard to use this library.

tensorboard # added

If some of you want to do the same for other notebooks, this is the regex I used:

Requirement already satisfied: ([\w\-=><\d.,!]*) in [\w\/\d.-]* \(([^()]|(?R))*\) \(([\d.]*)\)

finally I can play with it a bit.

Thanks - installing the requirements above enabled me to run the ensemble notebook

I'm so sorry for the trouble that you were having. "Easy to use" is not our primary goal, since we foresee the steep learning curve. We hope the ones that master those tools will win in the market.

[ShuningZhao]

@sebnapi what version of pip and python do you have? I tried to install your requirements.txt but it kept on failing.
