# Limited time hosted online gradio demo |
|
|
|
I will be hosting a demo online at [https://91ec98cb495732c0b9.gradio.live](https://91ec98cb495732c0b9.gradio.live) for about 10 hours. |
|
|
|
# Easy Windows & Linux install |
|
|
|
remghoost prepared a simple way to set up this demo on Windows and Linux |
|
|
|
[https://github.com/remghoost/meta-spirit-frontend](https://github.com/remghoost/meta-spirit-frontend) |
|
|
|
Please note that Windows version seems to perform around 10x slower in our limited testing. |

# Spirit LM Inference Gradio Demo |
|
|
|
Copy the github repo, build the [spiritlm](https://github.com/facebookresearch/spiritlm) python package and put models in `checkpoints` folder before running the script. I would suggest to use conda environment for this. |
|
|
|
You need around 15.5GB of VRAM to run the model with 200 tokens output length and around 19GB to output 800 tokens. |
|
|
|
If you're concerned about pickles from unknown uploader - grab them from a repo maintained by HF staffer - [https://huggingface.co/spirit-lm/Meta-spirit-lm](https://huggingface.co/spirit-lm/Meta-spirit-lm) |
|
|
|
Audio to audio inference doesn't seem good at all. Potentially I am tokenizing the audio wrong. Could be also that model doesn't work well with audio IN audio OUT. |
|
|
|
Script here works with just single speaker - if you know how to get other speakers let me know and I'll update it. |
|
|
|
to install requirements for the sample Gradio demo provided, please run: |
|
|
|
``` |
|
pip install torch torchaudio --index-url https://download.pytorch.org/whl/cu121 |
|
pip install gradio tempfile transformers numpy |
|
``` |
|
|
|
Remember that you also need to install the [spiritlm](https://github.com/facebookresearch/spiritlm) module. |
