or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.

documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.

agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

VisualGLM 模型架构是 ViT + QFormer + ChatGLM，在预训练阶段对 QFormer 和 ViT LoRA 进行训练，在微调阶段对 QFormer 和 ChatGLM LoRA 进行训练，训练目标是自回归损失（根据图像生成正确的文本）和对比损失（输入 ChatGLM 的视觉特征与对应文本的语义特征对齐）

VisualGLM-6B 是一个开源的，支持图像、中文和英文的多模态对话语言模型，语言模型基于 ChatGLM-6B，具有 62 亿参数；图像部分通过训练 BLIP2-Qformer 构建起视觉模型与语言模型的桥梁，整体模型共78亿参数。
VisualGLM-6B 由 SwissArmyTransformer(简称sat) 库训练，这是一个支持Transformer灵活修改、训练的工具库，支持Lora、P-tuning等参数高效微调方法。本项目提供了符合用户习惯的huggingface接口，也提供了基于sat的接口。
结合模型量化技术，用户可以在消费级的显卡上进行本地部署（INT4量化级别下最低只需6.3G显存）。

This is the configuration class to store the configuration of a [`~ChatGLMModel`].
It is used to instantiate an ChatGLM model according to the specified arguments, defining the model
architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of
the ChatGLM-6B [THUDM/ChatGLM-6B](https://huggingface.co/THUDM/chatglm-6b) architecture.

Vocabulary size of the ChatGLM-6B model. Defines the number of different tokens that can be represented by the
`inputs_ids` passed when calling [`~ChatGLMModel`] or
[`~TFChatGLMModel`].
hidden_size (`int`, *optional*, defaults to 4096):
Dimension of the encoder layers and the pooler layer.
num_hidden_layers (`int`, *optional*, defaults to 28):
Number of hidden layers in the Transformer encoder.
num_attention_heads (`int`, *optional*, defaults to 32):
Number of attention heads for each attention layer in the Transformer encoder.
inner_hidden_size (`int`, *optional*, defaults to 16384):
Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
max_sequence_length (`int`, *optional*, defaults to 512):
The maximum sequence length that this model might ever be used with.
Typically set this to something large just in case (e.g., 512 or 1024 or 2048).
layernorm_epsilon (`float`, *optional*, defaults to 1e-5):
The epsilon used by the layer normalization layers.
use_cache (`bool`, *optional*, defaults to `True`):
Whether the model should return the last key/values attentions (not used by all models).
Example:
```python
>>> from configuration_chatglm import ChatGLMConfig
>>> from modeling_chatglm import ChatGLMModel
>>> # Initializing a ChatGLM-6B THUDM/ChatGLM-6B style configuration
>>> configuration = ChatGLMConfig()
>>> # Initializing a model from the THUDM/ChatGLM-6B style configuration
>>> model = ChatGLMModel(configuration)
>>> # Accessing the model configuration
>>> configuration = model.config
```
