Getting ValueError for st.text_input

Where you see st.write(7) is the last number I see when I run the code I have to input a number in the input I showed you above but when that input runs afterwards I get the st.experimental_rerun error.

24

I don’t see st.write(7) in the snippet you posted, but assuming this is what immediately follows, my eyes are drawn to your loop and wondering if the model is executing correctly (or sufficiently quickly that it’s not a bottleneck). Try checking how the loop is progressing:

for i in range(len(final_weibos_new)):
    print(f'Starting iteration {i}')
    print(f'Looking at {final_weibos_new[i]}') # Or some variation, depending on how big it is to print a weibo
    sim = model.n_similarity(weibo_test, final_weibos_new[i])
    sim_list.append(sim)
    weibo_id.append(i)
25

st.write(7) was the line above first line I copied above. I can copy in your code and test it.

ok the code I copied in basically bypassed the error initially but it wouldn’t allow me to enter in the user input and then the code ran for the other parts and then gave the error at the end. Above are screenshots of the program after I ran it.

27

You’ve got an input statement after st.write(15). Make sure you don’t have Python input statements. You need to use Streamlit input elements.

Change this part:

sim_input = input("Enter a weibo id between 0 and " + str(num_weibos-1) + " to find the most similar weibo: ")
sim_input = int(sim_input)
28

Yeah I was trying to figure out what the correct syntax I tried to put the first in a st.write but I believe i got an error I wasn’t able to get those lines to work properly, any suggestions I tried to replicate the input mentioned above and follow that same format but it didn’t work.

29

I am referring to these lines.
label = “Enter a weibo id between 0 and " + str(max_num_weibos - 1) + " to find similar weibos:”
weibo_input = st.number_input(label, 0, max_num_weibos-1, value=0, step=1)
#print(“Finding similar weibos to weibo id:”, weibo_input, “…”)
st.write(5)
st.write(“These are similar weibos to weibo id entered:”, weibo_input, “…”)
#print(“\r”)
st.write(“\r”)

30

What error do you get when you use a Streamlit input for your sim_input? A specific error and trace would help, especially if this is the part that’s somehow contributing to the larger issue.

31

Unfortunately I do not know the code cuts out before that code can be initiated that is the problem with that st.experimental_rerun error.

32

Here is what happens when I enter a input into the first prompt.

User input

33

Ok. To recap so I understand where you are. You’ve got:

st.write(15)
sim_input = input("Enter a weibo id between 0 and " + str(num_weibos-1) + " to find the most similar weibo: ")
sim_input = int(sim_input)

You are not able to enter the number input into the terminal to continue?

If you use a Streamlit Input like this:

st.write(15)
sim_label = "Enter a weibo id between 0 and " + str(num_weibos-1) + " to find the most similar weibo:"
sim_input = st.number_input(sim_label, 0, num_weibos-1, value=0, step=1, key='sim_input')
sim_input = int(sim_input)

The widget does not render and you go straight to the experimental rerun warning?

34

No so it doesn’t even get to this point it only runs for the user input all the way at the beginning. In my screenshot above where the user is asked it input a number from 0-37339 with the question being Enter a Weibo id between those numbers. The code that supposedly stops the program from running is on line 107.

label = "Enter a weibo id between 0 and " + str(max_num_weibos - 1) + " to find similar weibos:"
    weibo_input = st.number_input(label, 0, max_num_weibos-1, value=0, step=1)
    #print("Finding similar weibos to weibo id:", weibo_input, ".....")
    st.write(5)
    st.write("These are similar weibos to weibo id entered:", weibo_input, ".....")
    #print("\r")
    st.write("\r")

After I enter in the weibo Id it says its running and then I get the calling st.experimental_rerun() with a callback is a no-op. error.

35

Can you:

  1. Clear your cache/reboot your app again.
  2. Add a keys to both inputs with a check on how session state is seeing them as follows.
label = "Enter a weibo id between 0 and " + str(max_num_weibos - 1) + " to find similar weibos:"
st.session_state
weibo_input = st.number_input(label, 0, max_num_weibos-1, value=0, step=1, key='weibo_input')
st.session_state

and the second input similarly:

sim_label = "Enter a weibo id between 0 and " + str(num_weibos-1) + " to find the most similar weibo:"
st.session_state
sim_input = st.number_input(sim_label, 0, num_weibos-1, value=0, step=1, key='sim_input')
st.session_state
36

Ok I tried copying in the code you sent above and I am still getting the callback error after I input a number into the first code block from above.

37

Please can you show the screen shots with the readout from session state and st.write outputs for clarity?

38

Sure! I want by the way thank you so much for the amount of help you giving me I really appreciate it!

erroraftersessionstate
erroraftersessionstate1917×895 28.5 KB

I looks to me to be acting the same!

39

Do you have the st.session_state lines, too? Streamlit magic should render those before and after the input if they are there.

40

Yeah I copied straight from your comment I also removed all the st.write statements I added but I am still getting the error.

41

I’m spinning up a VM and will run your code in debug to see if I can find where you get an st.experimental_rerun error without having the function called within the code. If you have any updates to include on your github, go ahead and push them. :smile:

42

Ok, no updates on my end just been trying to debug myself for the past 4 hours with no success!
