### How to use: |
|
|
|
```python |
|
# Use a pipeline as a high-level helper |
|
>>> from transformers import pipeline |
|
>>> pipe = pipeline("text-generation", model="lgaalves/gpt2-dolly") |
|
>>> question = "What is a large language model?" |
|
>>> answer = pipe(question) |
|
>>> print(answer[0]['generated_text']) |
|
What is a large language model? |
|
A large language model aims for understanding a large group of phenomena through computational methods which allow more precise models. |
|
A model also encourages the use of empirical concepts such as equations, models, natural numbers, natural language |
|
``` |
|
|
|
or, you can load the model direclty using: |
|
|
|
```python |
|
# Load model directly |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("lgaalves/gpt2-dolly") |
|
model = AutoModelForCausalLM.from_pretrained("lgaalves/gpt2-dolly") |
|
``` |
|
|
|
### Training Dataset |
|
|
|
`lgaalves/gpt2-dolly` trained using the Databricks Dolly dataset [`databricks/databricks-dolly-15k`](https://huggingface.co./datasets/databricks/databricks-dolly-15k). |
|
|
|
|
|
### Training Procedure |
|
|
|
`lgaalves/gpt2-dolly` was instruction fine-tuned using LoRA on 1 T4 GPU on Google Colab. It took about 1.5 hours to train it. |
|
|
|
|
|
# Intended uses, limitations & biases |
|
|
|
You can use the raw model for text generation or fine-tune it to a downstream task. The model was not extensively tested and may produce false information. It contains a lot of unfiltered content from the internet, which is far from neutral. |
