## MiniCPM-o 2.6
|
||||
Currently, this readme only supports minicpm-omni's image capabilities, and we will update the full-mode support as soon as possible.
|
||||
|
||||
### Prepare models and code
|
||||
|
||||
Download [MiniCPM-o-2_6](https://huggingface.co/openbmb/MiniCPM-o-2_6) PyTorch model from huggingface to "MiniCPM-o-2_6" folder.
|
||||
|
||||
Clone llama.cpp:
|
||||
```bash
|
||||
git clone git@github.com:OpenBMB/llama.cpp.git
|
||||
cd llama.cpp
|
||||
git checkout minicpm-omni
|
||||
```
|
||||
|
||||
### Usage of MiniCPM-o 2.6
|
||||
|
||||
Convert PyTorch model to gguf files (You can also download the converted [gguf](https://huggingface.co/openbmb/MiniCPM-o-2_6-gguf) by us)
|
||||
|
||||
```bash
|
||||
python ./examples/llava/minicpmv-surgery.py -m ../MiniCPM-o-2_6
|
||||
python ./examples/llava/minicpmv-convert-image-encoder-to-gguf.py -m ../MiniCPM-o-2_6 --minicpmv-projector ../MiniCPM-o-2_6/minicpmv.projector --output-dir ../MiniCPM-o-2_6/ --image-mean 0.5 0.5 0.5 --image-std 0.5 0.5 0.5 --minicpmv_version 4
|
||||
python ./convert_hf_to_gguf.py ../MiniCPM-o-2_6/model
|
||||
|
||||
# quantize int4 version
|
||||
./llama-quantize ../MiniCPM-o-2_6/model/ggml-model-f16.gguf ../MiniCPM-o-2_6/model/ggml-model-Q4_K_M.gguf Q4_K_M
|
||||
```
|
||||
|
||||
Build llama.cpp using `CMake`:
|
||||
https://github.com/ggerganov/llama.cpp/blob/master/docs/build.md
|
||||
|
||||
```bash
|
||||
cmake -B build
|
||||
cmake --build build --config Release
|
||||
```
|
||||
|
||||
Inference on Linux or Mac
|
||||
```
|
||||
# run f16 version
|
||||
./llama-minicpmv-cli -m ../MiniCPM-o-2_6/model/ggml-model-f16.gguf --mmproj ../MiniCPM-o-2_6/mmproj-model-f16.gguf -c 4096 --temp 0.7 --top-p 0.8 --top-k 100 --repeat-penalty 1.05 --image xx.jpg -p "What is in the image?"
|
||||
|
||||
# run quantized int4 version
|
||||
./llama-minicpmv-cli -m ../MiniCPM-o-2_6/model/ggml-model-Q4_K_M.gguf --mmproj ../MiniCPM-o-2_6/mmproj-model-f16.gguf -c 4096 --temp 0.7 --top-p 0.8 --top-k 100 --repeat-penalty 1.05 --image xx.jpg -p "What is in the image?"
|
||||
|
||||
# or run in interactive mode
|
||||
./llama-minicpmv-cli -m ../MiniCPM-o-2_6/model/ggml-model-Q4_K_M.gguf --mmproj ../MiniCPM-o-2_6/mmproj-model-f16.gguf -c 4096 --temp 0.7 --top-p 0.8 --top-k 100 --repeat-penalty 1.05 --image xx.jpg -i
