Support for --n-gpu-layers #586. 1. For VRAM only uses 0. TL;DR: this isn’t a ‘standard’ llama model, because of its YARN implementation of extended. --n-gpu-layers 36 is supposed to fill my VRAM and use my GPU, it's also supposed to print in the console llama_model_load_internal: [cublas] offloading 36 layers to GPU and I suppose it should be printing BLAS = 1. FSSRepo commented May 15, 2023. n_batch = 256 # Should be between 1 and n_ctx, consider the amount of VRAM in your GPU. This guide provides tips for improving the performance of fully-connected (or linear) layers. Offload 20-24 layers to your gpu for 6. Log: Starting the web UI. src. In the Continue configuration, add "from continuedev. Sorry for stupid question :) Suggestion: No response Issue you'd like to raise. Remember that the 13B is a reference to the number of parameters, not the file size. py - not. Based on your GPU you can probably fully offload that 13B model to the GPU and it should be pretty fast. Describe the bug. It also provides details on the impact of parameters including batch size, input and filter dimensions, stride, and dilation. You switched accounts on another tab or window. cpp (which is running your ggml model) is using your gpu for some things like "starting faster". n-gpu-layers decides how much layers will be offloaded to the GPU. The n_gpu_layers parameter can be adjusted according to the hardware limitations. --mlock: Force the system to keep the model. run (server, host = "0. . So I stareted searching, one of answers is command:The more layers you can load into GPU, the faster it can process those layers. Quite slow (1t/s) but for coding tasks works absolutely best from all models I've tried. Should be a number between 1 and n_ctx. If None, the number of threads is automatically determined. Should be a number between 1 and n_ctx. Otherwise, ignore it, as it makes prompt. But when loading it again, at least now it returns to the same usage it had before, so it should not run out of VRAM anymore, as far as I can tell. not great but already usableLLamaSharp 0. enhancement New feature or request. Set n-gpu-layers to 20. On top of that, it takes several minutes before it even begins generating the response. param n_ctx: int = 512 ¶ Token context window. Note: There are cases where we relax the requirements. I have tried running it with num_gpu 1 but that generated the warnings below. This allows you to use llama. If anyone has any ideas or can confirm if this model supports or does not support GPU Acceleration let me know. My question is, given the recent changes in gpu offloading, and now hearing about how exllama performs so well, I was looking for some sort of beginner advice from some of you veterans. Set it to "51" and load the model, then look at the command prompt. You should see gpu being used. leads to: Milestone. With a 6gb GPU, 25 layers is pretty much the max that it can hold, though you will run out of memory if you run the model long enough. 8-bit optimizers, 8-bit multiplication,. Less layers on the GPU will generally reduce inference speed but also VRAM usage. Supported Network Layers. A 33B model has more than 50 layers. Without any special settings, llama. main. n_gpu_layers = 40 # Change this value based on your model and your GPU VRAM pool. I tried with different numbers for pre_layer but without success. ”. Checklist for Memory-Limited Layers. So for example if you see a model that mentions 8GB of VRAM you can only put -1 if your GPU also has 8GB of VRAM (in some cases windows and other. ggmlv3. 2. 3-1. However the dedicated GPU memory usage does not return to the same level it was before first loading, and it still goes down further when terminating the python script.
