Yes that is correct.Takes care of removing and installing drivers to keep the google box current.

There is an Nvidia app that may help.

Only graphics card showing is "Intel(R) HD Graphics 620".

I cannot find anything about the NVIDIA graphics card. Not even MX150.
                   



Your GPU drivers probably got wiped out by a windows update. It happened to me. You'll need to reinstall the drivers for your GPU, as the other fellow recommended.

Use the BLAS version then which will use the CPU, it will be faster than OpenCL on the tiny GPU inside the CPU.

Windows probably updated the driver for the latter, on which OpenCL isn't very well tested as it is too weak to be useful anyway, and broke its OpenCL support completely.

In what you list above there's no GPU listed, so you want to use the BLAS version. OpenCL would be running on the GPU-built-into-the-CPU, which is extremely slow and buggy (and likely to be broken by Windows updates...), or under emulation on the CPU, which is also slow (and tends to be buggy).

But the manufacturer claims your laptop is also sold with:
NVIDIA® GeForce® MX150 or NVIDIA® GeForce® GTX 1050Ti with Max-Q Design

One of which is a uselessly small GPU (the MX150), and one of which is actually pretty good (GTX 1050 Ti) for a laptop.

So summarizing:
If your laptop actually has the GTX 1050 Ti, go the the NVIDIA website, download the latest drivers, and install those. This setup is fine for Leela (and CUDA would be expected to work).

If your laptop has any of the others (MX150, no GPU), use the BLAS version. And consider whether you want to use Leela at all, as it'll be weak.

My laptop is a HP Spectre 360. Intel Core i7-7500U CPU 2,70 GHz, 16 GB RAM, 64 bits. Windows 10 OS.

I use .opencl for Leela installation. The .cuda file never worked for me.

Do you mean that I should use the .blas version and see if it works, or just try to reinstall the drivers.

Without knowing your hardware, it's hard to say more.

There are 3 Leela version: (Open)BLAS, OpenCL and CUDA.

The last 2 run on the graphics card. A Windows update might have wrecked the graphics drivers. So you might want to reinstall those. Without knowing your hardware, again, it's impossible to say more.

The "Backend" is a setting in Leela. It describes what's running the computation. You expect "blas" when using OpenBLAS, "opencl" when using OpenCL, and "cudnn" when using CUDA. (Unless you have an RTX card, in which case it's "cudnn-fp16").

Which network are you using?


weights_run1_60683.pb.gz.

I had used a different one before, but I forgot which one because I deleted it when trying to fix my Leela. Both networks still have this problem.

All versions of Leela are doing this on my computer. 1. d4 Cf6 2. Ag5 e6 3. e4 h6 4. Axf6. All Leela 21.0-21.5 and 22.0 giving 4...g5 5. 5. Axd8 with -0,03 evaluation.

...

I feel like I should just forget about Leela and go back to Stockfish.

What backend are you using? I think Windows 10 bundles GFX drivers into these auto updates as well, so your Cuda/OpenCL backend might have got wrecked.

I tried Leela 21.4 and this one is also recommending lines hanging pieces. Just blatantly putting pieces en prise. Yet Komodo 10 and Stockfish 10 are working normal as usual.
