## MiniCPM-V 2.6
|
||||
|
||||
### Prepare models and code
|
||||
|
||||
Download [MiniCPM-V-2_6](https://huggingface.co/openbmb/MiniCPM-V-2_6) PyTorch model from huggingface to "MiniCPM-V-2_6" folder.
|
||||
|
||||
Clone llama.cpp:
|
||||
```bash
|
||||
git clone git@github.com:OpenBMB/llama.cpp.git
|
||||
cd llama.cpp
|
||||
git checkout minicpmv-main
|
||||
```
|
||||
|
||||
### Usage of MiniCPM-V 2.6
|
||||
|
||||
Convert PyTorch model to gguf files (You can also download the converted [gguf](https://huggingface.co/openbmb/MiniCPM-V-2_6-gguf) by us)
|
||||
|
||||
```bash
|
||||

|
||||
python ./examples/llava/minicpmv-convert-image-encoder-to-gguf.py -m ../MiniCPM-V-2_6 --minicpmv-projector ../MiniCPM-V-2_6/minicpmv.projector --output-dir ../MiniCPM-V-2_6/ --image-mean 0.5 0.5 0.5 --image-std 0.5 0.5 0.5 --minicpmv_version 3
|
||||
python ./convert_hf_to_gguf.py ../MiniCPM-V-2_6/model
|
||||
|
||||
# quantize int4 version
|
||||
./llama-quantize ../MiniCPM-V-2_6/model/ggml-model-f16.gguf ../MiniCPM-V-2_6/model/ggml-model-Q4_K_M.gguf Q4_K_M
|
||||
```
|
||||
|
||||
Build for Linux or Mac
|
||||
|
||||
```bash
|
||||
make
|
||||
make llama-minicpmv-cli
|
||||
```
|
||||
|
||||
Inference on Linux or Mac
|
||||
```
|
||||
# run f16 version
|
||||
./llama-minicpmv-cli -m ../MiniCPM-V-2_6/model/ggml-model-f16.gguf --mmproj ../MiniCPM-V-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-V-2_6/model/ggml-model-Q4_K_M.gguf --mmproj ../MiniCPM-V-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-V-2_6/model/ggml-model-Q4_K_M.gguf --mmproj ../MiniCPM-V-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
|
||||
```
|
||||
|
||||
### Video
|
||||
Install FFmpeg
|
||||
```
|
||||
brew install ffmpeg
|
||||
brew install pkg-config
|
||||
```
|
||||
|
||||
### Android
|
||||
|
||||
#### Build on Android device using Termux
|
||||
We found that build on Android device would bring better runtime performance, so we recommend to build on device.
|
||||
|
||||
[Termux](https://github.com/termux/termux-app#installation) is a terminal app on Android device (no root required).
|
||||
|
||||
Install tools in Termux:
|
||||
```
|
||||
apt update && apt upgrade -y
|
||||
apt install git make cmake
|
||||
```
|
||||
|
||||
It's recommended to move your model inside the `~/` directory for best performance:
|
||||
```
|
||||
cd storage/downloads
|
||||
mv model.gguf ~/
|
||||
```
|
||||
|
||||
#### Building the Project using Android NDK
|
||||
Obtain the [Android NDK](https://developer.android.com/ndk) and then build with CMake.
|
||||
|
||||
Execute the following commands on your computer to avoid downloading the NDK to your mobile. Alternatively, you can also do this in Termux:
|
||||
|
||||
```bash
|
||||
mkdir build-android
|
||||
cd build-android
|
||||
export NDK=/your_ndk_path
|
||||
cmake -DCMAKE_TOOLCHAIN_FILE=$NDK/build/cmake/android.toolchain.cmake -DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=android-23 -DCMAKE_C_FLAGS=-march=armv8.4a+dotprod ..
|
||||
make
|
||||
```
|
||||
|
||||
Install [termux](https://github.com/termux/termux-app#installation) on your device and run `termux-setup-storage` to get access to your SD card (if Android 11+ then run the command twice).
|
||||
|
||||
Finally, copy these built `llama` binaries and the model file to your device storage. Because the file permissions in the Android sdcard cannot be changed, you can copy the executable files to the `/data/data/com.termux/files/home/bin` path, and then execute the following commands in Termux to add executable permission:
|
||||
|
||||
(Assumed that you have pushed the built executable files to the /sdcard/llama.cpp/bin path using `adb push`)
|
||||
```
|
||||
$cp -r /sdcard/llama.cpp/bin /data/data/com.termux/files/home/
|
||||
$cd /data/data/com.termux/files/home/bin
|
||||
$chmod +x ./*
|
||||
```
|
||||
|
||||
Download models and push them to `/sdcard/llama.cpp/`, then move it to `/data/data/com.termux/files/home/model/`
|
||||
|
||||
```
|
||||
$mv /sdcard/llama.cpp/ggml-model-Q4_K_M.gguf /data/data/com.termux/files/home/model/
|
||||
$mv /sdcard/llama.cpp/mmproj-model-f16.gguf /data/data/com.termux/files/home/model/
|
||||
```
|
||||
|
||||
Now, you can start chatting:
|
||||
```
|
||||
$cd /data/data/com.termux/files/home/bin
|
||||
$./llama-minicpmv-cli -m ../model/ggml-model-Q4_K_M.gguf --mmproj ../model/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?"

class SiglipVisionConfig(PretrainedConfig):
|

r"""
|
||||
This is the configuration class to store the configuration of a [`SiglipVisionModel`]. It is used to instantiate a
|
||||
Siglip vision encoder according to the specified arguments, defining the model architecture. Instantiating a
|
||||
configuration with the defaults will yield a similar configuration to that of the vision encoder of the Siglip
|
||||
[google/siglip-base-patch16-224](https://huggingface.co/google/siglip-base-patch16-224) architecture.
|
||||
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
||||
documentation from [`PretrainedConfig`] for more information.
|
||||
Args:
|
||||
hidden_size (`int`, *optional*, defaults to 768):
|
||||
Dimensionality of the encoder layers and the pooler layer.
|
||||
intermediate_size (`int`, *optional*, defaults to 3072):
|
||||
Dimensionality of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
|
||||
num_hidden_layers (`int`, *optional*, defaults to 12):
|
||||
Number of hidden layers in the Transformer encoder.
|
||||
num_attention_heads (`int`, *optional*, defaults to 12):
|
||||
Number of attention heads for each attention layer in the Transformer encoder.
|
||||
num_channels (`int`, *optional*, defaults to 3):
|
||||
Number of channels in the input images.
|
||||
image_size (`int`, *optional*, defaults to 224):
|
||||
The size (resolution) of each image.
|
||||
patch_size (`int`, *optional*, defaults to 16):
|
||||
The size (resolution) of each patch.
|
||||
hidden_act (`str` or `function`, *optional*, defaults to `"gelu_pytorch_tanh"`):
|
||||
The non-linear activation function (function or string) in the encoder and pooler. If string, `"gelu"`,
|
||||
`"relu"`, `"selu"` and `"gelu_new"` ``"quick_gelu"` are supported.
|
||||
layer_norm_eps (`float`, *optional*, defaults to 1e-06):
|
||||
The epsilon used by the layer normalization layers.
|
||||
attention_dropout (`float`, *optional*, defaults to 0.0):
|
||||
The dropout ratio for the attention probabilities.
|
||||
Example:
|
||||
```python
|
||||
>>> from transformers import SiglipVisionConfig, SiglipVisionModel
|
||||
>>> # Initializing a SiglipVisionConfig with google/siglip-base-patch16-224 style configuration

>>> # Initializing a SiglipVisionModel (with random weights) from the google/siglip-base-patch16-224 style configuration

SIGLIP_START_DOCSTRING = r"""
|
||||
This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
|
||||
library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
|
||||
etc.)
|
||||
This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
|
||||
Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
|
||||
and behavior.
|
||||
Parameters:
|
||||
config ([`SiglipVisionConfig`]): Model configuration class with all the parameters of the model.
|
||||
Initializing with a config file does not load the weights associated with the model, only the
|
||||
configuration. Check out the [`~PreTrainedModel.from_pretrained`] method to load the model weights.

pixel_values (`torch.FloatTensor` of shape `(batch_size, num_channels, height, width)`):

Pixel values. Padding will be ignored by default should you provide it. Pixel values can be obtained using
|

[`AutoImageProcessor`]. See [`CLIPImageProcessor.__call__`] for details.
|

output_attentions (`bool`, *optional*):
|

Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned

tensors for more detail.

Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
