I am having a problem setting Leela on ChessBase 15. How did you make it work there to analyse  ¿

did you follow the instructions at https://github.com/LeelaChessZero/lc0/wiki/Getting-Started ?
first you need a 'weights'-file from http://lczero.org/networks, presumably one with high elo, and then you need to open the lc0.exe file to initialise the configuration (this takes a while)
also important is to have the right drivers for the GPU (for Cuda or for Opencl), this took me a whole day to get this right at my new Ubuntu laptop, on an old Windows 7 laptop the lc0 program just crashed after a while
now that it's finally working I have to say it's pretty slow and I barely can move my mouse while it's analysing, I suppose you need a GPU with Cuda support (I have to use Opencl) for it to make any sense using Leela for analysis

edit: when I use 'blas' as backend instead of 'opencl' (so using CPU iso GPU), I can actually use my computer while analysing but the engine is of course even slower then
for info: I have AMD A6-9220 radeon r4 as processor with AMD Stoney as graphics card, so new but not very strong

My laptop GPU is non CUDA, so I would have to buy new hardware, otherwise Stockfish is stronger. I'm too frugal for that, but also, I honestly don't see why I should care. In most cases I just use whatever engine is available in the GUI of the moment. That might be Shredder, Stockfish (10 or 9 or even 8), Crafty, Fritz.

My old car already goes faster than the speed limit, I don't care that a Tesla can go from 0 to 100 km/h in 2.3 seconds. If you point out that I would care in a race, my answer is that in the race we won't be using the car...

The superfinal of TCEC season 15 is ongoing and it looks like Leela has surpassed Stockfish. At this moment the score is 23-18: https://tcec.chessdom.com/

It is time to start using Leela instead of Stockfish as main-engine. I hear some people having troubles to let Leela work properly in Chessbase. I didn't try it out yet so does anybody has experience with it?

It should be, but running Lc0 at the same time is probably still going to be worth it in some positions

Quite agree that one do much better with only 1 good engine than a few years ago... even if I still think that "difference" always brings something in making an opinion (like in medicine )  If I had 2 computers available, I'd run 2 different engines at the same time anyway.

Me too - I make no claims about the accuracy!

Thanks TonyRo, a friend of mine said just about the same.
