See below for instructions on fetching from different branches. + +Most GPTQ files are made with AutoGPTQ. Mistral models are currently made with Transformers. + +
+ Explanation of GPTQ parameters + +- Bits: The bit size of the quantised model. +- GS: GPTQ group size. Higher numbers use less VRAM, but have lower quantisation accuracy. "None" is the lowest possible value. +- Act Order: True or False. Also known as `desc_act`. True results in better quantisation accuracy. Some GPTQ clients have had issues with models that use Act Order plus Group Size, but this is generally resolved now. +- Damp %: A GPTQ parameter that affects how samples are processed for quantisation. 0.01 is default, but 0.1 results in slightly better accuracy. +- GPTQ dataset: The calibration dataset used during quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ calibration dataset is not the same as the dataset used to train the model - please refer to the original model repo for details of the training dataset(s). +- Sequence Length: The length of the dataset sequences used for quantisation. Ideally this is the same as the model sequence length. For some very long sequence models (16+K), a lower sequence length may have to be used. Note that a lower sequence length does not limit the sequence length of the quantised model. It only impacts the quantisation accuracy on longer inference sequences. +- ExLlama Compatibility: Whether this file can be loaded with ExLlama, which currently only supports Llama models in 4-bit. + +

+ More advanced huggingface-cli download usage + +If you remove the `--local-dir-use-symlinks False` parameter, the files will instead be stored in the central Huggingface cache directory (default location on Linux is: `~/.cache/huggingface`), and symlinks will be added to the specified `--local-dir`, pointing to their real location in the cache. This allows for interrupted downloads to be resumed, and allows you to quickly clone the repo to multiple places on disk without triggering a download again. The downside, and the reason why I don't list that as the default option, is that the files are then hidden away in a cache folder and it's harder to know where your disk space is being used, and to clear it up if/when you want to remove a download model. + +The cache location can be changed with the `HF_HOME` environment variable, and/or the `--cache-dir` parameter to `huggingface-cli`. + +For more documentation on downloading with `huggingface-cli`, please see: [HF -> Hub Python Library -> Download files -> Download from the CLI](https://huggingface.co/docs/huggingface_hub/guides/download#download-from-the-cli). + +To accelerate downloads on fast connections (1Gbit/s or higher), install `hf_transfer`: + +```shell +pip3 install hf_transfer +``` + +And set environment variable `HF_HUB_ENABLE_HF_TRANSFER` to `1`: + +```shell +mkdir samantha-1.2-mistral-7B-GPTQ +HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download TheBloke/samantha-1.2-mistral-7B-GPTQ --local-dir samantha-1.2-mistral-7B-GPTQ --local-dir-use-symlinks False +``` + +Windows Command Line users: You can set the environment variable by running `set HF_HUB_ENABLE_HF_TRANSFER=1` before the download command. +
+ +### With `git` (**not** recommended) + +To clone a specific branch with `git`, use a command like this: + +```shell +git clone --single-branch --branch gptq-4bit-32g-actorder_True https://huggingface.co/TheBloke/samantha-1.2-mistral-7B-GPTQ +``` + +Note that using Git with HF repos is strongly discouraged. It will be much slower than using `huggingface-hub`, and will use twice as much disk space as it has to store the model files twice (it stores every byte both in the intended target folder, and again in the `.git` folder as a blob.) + + + +## How to easily download and use this model in [text-generation-webui](https://github.com/oobabooga/text-generation-webui). + +Please make sure you're using the latest version of [text-generation-webui](https://github.com/oobabooga/text-generation-webui). + +It is strongly recommended to use the text-generation-webui one-click-installers unless you're sure you know how to make a manual install. + +1. Click the **Model tab**. +2. Under **Download custom model or LoRA**, enter `TheBloke/samantha-1.2-mistral-7B-GPTQ`. + - To download from a specific branch, enter for example `TheBloke/samantha-1.2-mistral-7B-GPTQ:gptq-4bit-32g-actorder_True` + - see Provided Files above for the list of branches for each option. +3. Click **Download**. +4. The model will start downloading. Once it's finished it will say "Done". +5. In the top left, click the refresh icon next to **Model**. +6. In the **Model** dropdown, choose the model you just downloaded: `samantha-1.2-mistral-7B-GPTQ` +7. The model will automatically load, and is now ready for use! +8. If you want any custom settings, set them and then click **Save settings for this model** followed by **Reload the Model** in the top right. + * Note that you do not need to and should not set manual GPTQ parameters any more. These are set automatically from the file `quantize_config.json`. +9. Once you're ready, click the **Text Generation tab** and enter a prompt to get started! + + + + +## Serving this model from Text Generation Inference (TGI) + +It's recommended to use TGI version 1.1.0 or later.

Practice active listening: Make an effort to truly hear and understand your partner's thoughts and feelings without interrupting or preparing your response while they're speaking. +2. Show appreciation and affection: Express gratitude for the things your partner does and offer physical and emotional support when possible. +3. Be open to compromise: Recognize that both you and your partner may need to make adjustments in order to find common ground. +4. Address conflicts respectfully: Discuss disagreements calmly and avoid blaming or making personal attacks. Focus on finding solutions rather than assigning blame. +5. Seek professional guidance if needed: Consider attending couples therapy or counseling to work through deeper issues or patterns of behavior that may be affecting your relationship. + +Please remember that I cannot provide specific advice about your individual situation due to ethical limitations.
