Can anybody else replicate this error I’m seeing? Streamlit version 0.73.0 and 0.72.0
input_step = st.number_input("Step") my_range = st.slider("Range", 20, 120, step=int(input_step))
The preceeding code results in my chrome returning an Out of Memory error code.
No console error is logged. However, if I change the
st.number_input to provide a default value for the input_step, like so:
input_step = st.number_input("Step", value=5) my_range = st.slider("Range", 20, 120, step=int(input_step))
This code produces the desired result. Digging into the slider.py file, it seems like
st.slider should be able to handle a None value with the following code, line 192:
step = DEFAULTS[data_type]["step"]
Doing a little more digging, I found that
input_step = int(st.number_input("Step")) my_range = st.slider("Range", 20, 120, step=input_step)
will also lead to a crash but only in the st.slider line.
input_step = int(st.number_input("Step")) alone isn’t enough to crash streamlit, but passing the value into a subsequent widget is. So it seems that the mistake might be mine: that I can’t pass in int(None) as a step value to the
st.slider, which makes sense as it’s a type error. Perhaps catching this as a TypeError would be a good thing to add?
Title of this post has been changed accordingly (from Possible memory leak: passing input of st.number_input without a default value to a subsequent st.slider will crash streamlit)
(also, is there a forum tag for bugs? I couldn’t find one in the dropdown menu here)
