Version .2 available.
Fritz Update in addition.
By the way, the multi gpu syntax "(backend=cuda-fp16,gpu=0),(backend=cuda-fp16,gpu=1)" does not work on Fat Fritz though. Do anyone know a quick fix ?

It does not work on my system either! Ryzen Cpu, RTX 2070

No new 20x256 net and the new FatFritz 1.2-binary still does not support Cuda 11, which makes Lc0 run more than +35% faster on NVIDIA RTX GPUs.
OMG Chessbase, what are you doing?...
So, if anybody wants to use the FatFritz 20x256 net, just take Lc0 0.26.3-binary (Fat Fritz-binary is just a copy & paste- Lc0-binary). Update your NVIDIA driver and use the CUDA 11 version of Lc0 0.26.3. Then, FatFritz-net is at least running faster (only on RTX-GPUs! Otherwise use the older Lc0 Cuda-binary)
Cuda 11 Lc0-binary:

Re: Fat Fritz Update
Only a new NET what is about ~70 Elo weaker than the actual Leela NET on the same GPU(s).pohl4711 wrote: ↑Thu Dec 10, 2020 12:38 pm...Nordlandia wrote: ↑Wed Dec 09, 2020 11:37 pm Version .2 available.

Maybe
Backend = Multiplexing
BackendOptions = (backend=cudnn-fp16,gpu=0),(backend=cudnn-fp16,gpu=1)
will work on a dual GPUs

Seems like it supports Cuda to me:

Re: Fat Fritz Update
I forgot to point to the weights file so it chose FatFritzCpu.weights. It should be FatFritz.weights for GPU.

Re: Fat Fritz Update
Strange, I used the Fat Fritz 20x256 net and on my RTX 2060, Fat Fritz 1.2 did not run with new CUDA 11 libraries. But without releasing a new FatFritz-net, the Fat Fritz 1.2 binary alone is complete useless - so who cares? The old Fat Fritz net can be used with Lc0 0.26.3 binary...cc2150dx wrote: ↑Sat Dec 12, 2020 3:47 am Seems like it supports Cuda to me:

Re: Fat Fritz Update
It should come with the CUDA 11 libraries itself. The update was only because there were complaints it would not work with the new 30xx cards. The Lc0 it uses is faster, but it was not the reason for the update. I stopped development of the NN itself back in February.pohl4711 wrote: ↑Sat Dec 12, 2020 12:33 pmStrange, I used the Fat Fritz 20x256 net and on my RTX 2060, Fat Fritz 1.2 did not run with new CUDA 11 libraries.

Re: Fat Fritz Update
Albert Silver: is there any plans to resume NN improvement at some point later on ?

So the new(.2)net = the old(.1) one?Albert Silver wrote: ↑Sat Dec 12, 2020 6:20 pm ...

The -70 Elo difference is not a motive for development?
