Python library for easily interacting with trained machine learning models
## Installation
```bash
pip install gradio_variableslider
```
## Usage
```python
import gradio as gr
from gradio_variableslider import VariableSlider
example = VariableSlider().example_value()
with gr.Blocks() as demo:
sub_slider = gr.Slider(label="Sub-Divisions", minimum=5, maximum=1000, step=5, value=1000, info="This is the amount of values that will occur between each integer.", interactive=True)
def slider_function(slider_val):
step = round(1/slider_val, 3)
slider_final = VariableSlider(minimum=step, maximum=3.00001, step=step, interactive=True)
return slider_final
alpha_slider = VariableSlider(label="Alpha", minimum=0, maximum=3.00001, step=0.01, interactive=True)
sub_slider.release(fn=slider_function, inputs=sub_slider, outputs=alpha_slider)
if __name__ == "__main__":
demo.queue().launch()
```

### Events
| name | description |
|:-----|:------------|
| `change` | Triggered when the value of the VariableSlider changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See `.input()` for a listener that is only triggered by user input. |
| `input` | This listener is triggered when the user changes the value of the VariableSlider. |
| `release` | This listener is triggered when the user releases the mouse on this VariableSlider. |
### User function
The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).
- When used as an Input, the component only impacts the input signature of the user function.
- When used as an output, the component only impacts the return signature of the user function.
The code snippet below is accurate in cases where the component is used as both an input and an output.
- **As output:** Is passed, passes slider value as a {float} into the function.
- **As input:** Should return, expects an {int} or {float} returned from function and sets slider value to it as long as it is within range (otherwise, sets to minimum value).
```python
def predict(
value: float
) -> float | None:
return value
```
