FloatSlider and IntSlider didn't show up!

[tasanyphy01773]

I'm using ipywidget for metPy dewdrop calculator. But the sliders didn't show up when I run the code.
My Code:

import metpy.calc as mpcalc
from metpy.units import units 

from ipywidgets import interact, FloatSlider, IntSlider

def dewpoint_calculator(temperature, rh):
    temperature = temperature * units.degC
    rh = rh * units.percent
    return round(mpcalc.dewpoint_from_relative_humidity(temperature, rh).to('degC'), 1)

temp_slider = FloatSlider(min=0, max=100, step=0.5, value= 50)
rh_slider = IntSlider(min=0, max=100, value= 50)

interact(dewpoint_calculator, temperature=temp_slider, rh =rh_slider);

It should be like this:

I went ahead and installed metpy to see if I could reproduce,
the widget shows up fine for me.

Here are my package versions:
metpy = 1.0.1
jupyterlab = 3.0.15
ipywidgets = 7.6.3

Here is the code and output (thank you for including the code to reproduce):

If you are using chrome - have you checked the console to see if you are getting any errors?

Have you tried doing this in a clean python environment?
