+# Chaoyi Wu's PMC_LLAMA 7B 10 Epoch GPTQ
+
+These files are GPTQ 4bit model files for [Chaoyi Wu's PMC_LLAMA 7B 10 Epoch](https://huggingface.co/chaoyi-wu/PMC_LLAMA_7B_10_epoch) merged with [Kaio Ken's SuperHOT 8K](https://huggingface.co/kaiokendev/superhot-7b-8k-no-rlhf-test).
+
+It is the result of quantising to 4bit using [GPTQ-for-LLaMa](https://github.com/qwopqwop200/GPTQ-for-LLaMa).
+
+**This is an experimental new GPTQ which offers up to 8K context size**
+
+The increased context is tested to work with [ExLlama](https://github.com/turboderp/exllama), via the latest release of [text-generation-webui](https://github.com/oobabooga/text-generation-webui).
+
+It has also been tested from Python code using AutoGPTQ, and `trust_remote_code=True`.
+
+Code credits:
+- Original concept and code for increasing context length: [kaiokendev](https://huggingface.co/kaiokendev)
+- Updated Llama modelling code that includes this automatically via trust_remote_code: [emozilla](https://huggingface.co/emozilla).
+
+Please read carefully below to see how to use it.

+
+## How to easily download and use this model in text-generation-webui with ExLlama
+
+Please make sure you're using the latest version of text-generation-webui
+
+1. Click the **Model tab**.
+2. Under **Download custom model or LoRA**, enter `TheBloke/PMC_LLAMA-7B-10-Epoch-SuperHOT-8K-GPTQ`.
+3. Click **Download**.
+4. The model will start downloading. Once it's finished it will say "Done"
+5. Untick **Autoload the model**
+6. In the top left, click the refresh icon next to **Model**.
+7. In the **Model** dropdown, choose the model you just downloaded: `PMC_LLAMA-7B-10-Epoch-SuperHOT-8K-GPTQ`
+8. To use the increased context, set the **Loader** to **ExLlama**, set **max_seq_len** to 8192 or 4096, and set **compress_pos_emb** to **4** for 8192 context, or to **2** for 4096 context.
+9. Now click **Save Settings** followed by **Reload**
+10. The model will automatically load, and is now ready for use!
+11. Once you're ready, click the **Text Generation tab** and enter a prompt to get started!
+
+## How to use this GPTQ model from Python code with AutoGPTQ
+
+First make sure you have AutoGPTQ and Einops installed:
+
+```
+pip3 install einops auto-gptq
+```
+
+Then run the following code. Note that in order to get this to work, `config.json` has been hardcoded to a sequence length of 8192.
+
+If you want to try 4096 instead to reduce VRAM usage, please manually edit `config.json` to set `max_position_embeddings` to the value you want.
+
+```python
+from transformers import AutoTokenizer, pipeline, logging
+from auto_gptq import AutoGPTQForCausalLM, BaseQuantizeConfig
+import argparse
+
+model_name_or_path = "TheBloke/PMC_LLAMA-7B-10-Epoch-SuperHOT-8K-GPTQ"
+model_basename = "pmc_llama-7b-10-epoch-superhot-8k-GPTQ-4bit-128g.no-act.order"
+
+use_triton = False
+
+tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, use_fast=True)
+
+model = AutoGPTQForCausalLM.from_quantized(model_name_or_path,
+        model_basename=model_basename,
+        use_safetensors=True,
+        trust_remote_code=True,
+        device_map='auto',
+        use_triton=use_triton,
+        quantize_config=None)
+
+model.seqlen = 8192
+
+# Note: check the prompt template is correct for this model.
+prompt = "Tell me about AI"
+prompt_template=f'''USER: {prompt}
+ASSISTANT:'''
+
+print("\n\n*** Generate:")
+
+input_ids = tokenizer(prompt_template, return_tensors='pt').input_ids.cuda()
+output = model.generate(inputs=input_ids, temperature=0.7, max_new_tokens=512)
+print(tokenizer.decode(output[0]))
+
+# Inference can also be done using transformers' pipeline
+
+# Prevent printing spurious transformers error when using pipeline with AutoGPTQ
+logging.set_verbosity(logging.CRITICAL)
+
+print("*** Pipeline:")
+pipe = pipeline(
+    "text-generation",
+    model=model,
+    tokenizer=tokenizer,
+    max_new_tokens=512,
+    temperature=0.7,
+    top_p=0.95,
+    repetition_penalty=1.15
+)
+
+print(pipe(prompt_template)[0]['generated_text'])
+```
+
+## Using other UIs: monkey patch
+
+Provided in the repo is `llama_rope_scaled_monkey_patch.py`, written by @kaiokendev.
+
+It can be theoretically be added to any Python UI or custom code to enable the same result as `trust_remote_code=True`.  I have not tested this, and it should be superseded by using `trust_remote_code=True`, but I include it for completeness and for interest.
+
+## Provided files
+
+**pmc_llama-7b-10-epoch-superhot-8k-GPTQ-4bit-128g.no-act.order.safetensors**
+
+This will work with AutoGPTQ, ExLlama, and CUDA versions of GPTQ-for-LLaMa. There are reports of issues with Triton mode of recent GPTQ-for-LLaMa. If you have issues, please use AutoGPTQ instead.
+
+It was created with group_size 128 to increase inference accuracy, but without --act-order (desc_act) to increase compatibility and improve inference speed.
+
+* `pmc_llama-7b-10-epoch-superhot-8k-GPTQ-4bit-128g.no-act.order.safetensors`
+  * Works for use with ExLlama with increased context (4096 or 8192)
+  * Works with AutoGPTQ in Python code, including with increased context, if `trust_remote_code=True` is set.
+  * Should work with GPTQ-for-LLaMa in CUDA mode, but unknown if increased context works - TBC.  May have issues with GPTQ-for-LLaMa Triton mode.
+  * Works with text-generation-webui, including one-click-installers.
+  * Parameters: Groupsize = 128. Act Order / desc_act = False.

+# Original model card: Kaio Ken's SuperHOT 8K
+
+
+### SuperHOT Prototype 2 w/ 8K Context
+
+This is a second prototype of SuperHOT, a NSFW focused LoRA, this time 7B with 8K context and no RLHF, using the same technique described in [the github blog](https://kaiokendev.github.io/til#extending-context-to-8k).
+
+#### Looking for Merged & Quantized Models?
+Make some please :)
+
+#### Using the monkey-patch?
+You will **NEED** to **apply the monkeypatch** or, if you are already using the monkeypatch, **change the scaling factor to 0.25 and the maximum sequence length to 8192**
+
+The monkeypatch is only necessary if you are using a front-end/back-end that does not already support scaling and said front-end/back-end is Python-based (i.e. Huggingface Transformers). To apply the patch, you will need to copy the `llama_rope_scaled_monkey_patch.py` into your working directory and call the exported function `replace_llama_rope_with_scaled_rope` at the very start of your Python program. It will modify the Transformers library's implementation of RoPE to properly apply the scaling factor.
+
+#### Using Oobabooga with Exllama?
+Switch your loader to `exllama` or `exllama_hf` Add the arguments `max_seq_len 8192` and `compress_pos_emb 4`. **While the model may work well with `compress_pos_emb 2`, it was trained on 4, so that is what I advocate for you to use**
+
+Example in the command-line:
+- `python server.py --max_seq_len 8192 --compress_pos_emb 4 --loader exllama_hf`
+
+In the UI, you will see the loader option in the `Models` tab. Once you select either `exllama` or `exllama_hf`, the `max_seq_len` and `compress_pos_emb` settings will appear.
+
+#### Training Details
+I trained the LoRA with the following configuration:
+- 1200 samples (~400 samples over 2048 sequence length)
+- learning rate of 3e-4
+- 3 epochs
+- The exported modules are:
+    - q_proj
+    - k_proj
+    - v_proj
+    - o_proj
+    - no bias
+- Rank = 4
+- Alpha = 8
+- no dropout
+- weight decay of 0.1
+- AdamW beta1 of 0.9 and beta2 0.99, epsilon of 1e-5
+- Trained on 4-bit base model
+- Cutoff length: 4096

+# Original model card: Chaoyi Wu's PMC_LLAMA 7B 10 Epoch
+
+
+This repo contains the latest version of PMC_LLaMA_7B, which is LLaMA-7b finetuned on the PMC papers in the S2ORC dataset.
+
+Notably, different from `chaoyi-wu/PMC_LLAMA_7B`, this model is further trained for 10 epochs.
+
+The model was trained with the following hyperparameters:
+
+* Epochs: **10** 
+* Batch size: 128 
+* Cutoff length: 512
+* Learning rate: 2e-5
+
+Each epoch we sample 512 tokens per paper for training.
+
+The model can be loaded as follows:
+
+```
+import transformers
+import torch
+tokenizer = transformers.LlamaTokenizer.from_pretrained('chaoyi-wu/PMC_LLAMA_7B_10_epoch')
+model = transformers.LlamaForCausalLM.from_pretrained('chaoyi-wu/PMC_LLAMA_7B_10_epoch')
+sentence = 'Hello, doctor' 
+batch = tokenizer(
+            sentence,
+            return_tensors="pt", 
+            add_special_tokens=False
+        )
+with torch.no_grad():
+    generated = model.generate(inputs = batch["input_ids"], max_length=200, do_sample=True, top_k=50)
+    print('model predict: ',tokenizer.decode(generated[0]))
+```
