Unsloth
FastModel supports loading nearly any model now! This includes Vision and Text models!
Thank you to Etherl for creating this notebook!

We now add LoRA adapters so we only need to update 1 to 10% of all parameters!
Data Prep
We will use the MrDragonFox/Elise, which is designed for training TTS models. Ensure that your dataset follows the required format: text, audio for single-speaker models or source, text, audio for multi-speaker models. You can modify this section to accommodate your own dataset, but maintaining the correct structure is essential for optimal training.
Map: 0%| | 0/1195 [00:00<?, ? examples/s]
Filter: 0%| | 0/1195 [00:00<?, ? examples/s]

*** HERE you can modify the text prompt
If you are training a multi-speaker model (e.g., canopylabs/orpheus-3b-0.1-ft),
ensure that the dataset includes a "source" field and format the input accordingly:
- Single-speaker: f"{example['text']}"
- Multi-speaker: f"{example['source']}: {example['text']}"Map: 0%| | 0/1195 [00:00<?, ? examples/s]
Train the model
Now let's use Hugging Face Trainer! More docs here: Transformers docs. We do 60 steps to speed things up, but you can set num_train_epochs=1 for a full run, and turn off max_steps=None.
Note: Using a per_device_train_batch_size >1 may lead to errors if multi-GPU setup to avoid issues, ensure CUDA_VISIBLE_DEVICES is set to a single GPU (e.g., CUDA_VISIBLE_DEVICES=0).
GPU = Tesla T4. Max memory = 14.741 GB. 5.713 GB of memory reserved.

Hey there my name is Elise, <giggles> and I'm a speech generation model that can sound like a person.

, 'lora_model/tokenizer.json') Saving to float16
We also support saving to float16 directly. Select merged_16bit for float16 or merged_4bit for int4. We also allow lora adapters as a fallback. Use push_to_hub_merged to upload to your Hugging Face account! You can go to https://huggingface.co/settings/tokens for your personal tokens. See our docs for more deployment options.
Unsloth: You have 1 CPUs. Using `safe_serialization` is 10x slower. We shall switch to Pytorch saving, which might take 3 minutes and not 30 minutes. To force `safe_serialization`, set it to `None` instead. Unsloth: Kaggle/Colab has limited disk space. We need to delete the downloaded model which will save 4-16GB of disk space, allowing you to save on Kaggle/Colab. Unsloth: Will remove a cached repo with size 15.1G
Unsloth: Merging 4bit and LoRA weights to 16bit... Unsloth: Will use up to 3.99 out of 12.67 RAM for saving. Unsloth: Saving model... This might take 5 minutes ...
