#@title 🤗 AutoTrain LLM
#@markdown In order to use this colab
#@markdown - upload train.csv to a folder named `data/`
#@markdown - train.csv must contain a `text` column
#@markdown - choose a project name if you wish
#@markdown - change model if you wish, you can use most of the text-generation models from Hugging Face Hub
#@markdown - add huggingface information (token) if you wish to push trained model to huggingface hub
#@markdown - update hyperparameters if you wish
#@markdown - click `Runtime > Run all` or run each cell individually
#@markdown - report issues / feature requests here: https://github.com/huggingface/autotrain-advanced/issues

#@markdown #### Project Config
#@markdown Note: if you are using a restricted/private model, you need to enter your Hugging Face token in the next step.
project_name = 'my-autotrain-llm' # @param {type:"string"}

#@markdown ---
#@markdown #### Push to Hub?
#@markdown Use these only if you want to push your trained model to a private repo in your Hugging Face Account
#@markdown If you dont use these, the model will be saved in Google Colab and you are required to download it manually.
#@markdown Please enter your Hugging Face write token. The trained model will be saved to your Hugging Face account.
#@markdown You can find your token here: https://huggingface.co/settings/tokens
