ModuleNotFoundError: No module named 'streamlit.report_thread'

Aditya_Chache · January 14, 2022, 2:27pm

I’m trying to deploy an object detection web app on streamlit cloud but it’s throwing me this error

File “/home/appuser/venv/lib/python3.7/site-packages/streamlit_webrtc/session_info.py”, line 1, in
import streamlit.report_thread as ReportThread

the app runs fine on my local setup

here is the github repo of the project

here is the piece of code from the file which i think throws the error

Hello @Aditya_Chache, welcome to the community!

We’ve seen the issue appear this morning with the new 1.4.0 release, for now if you are in a hurry you can downgrade back to streamlit==1.3.1.

Do you use any old Session State code or external Streamlit package aside from streamlit-webrtc ? That will help the team diagnose the problem.

PS: wait, I think, @whitphx are you calling streamlit.report_thread in streamlit-webrtc ? I submitted an issue ModuleNotFoundError: No module named 'streamlit.report_thread' on Streamlit 1.4.0 · Issue #598 · whitphx/streamlit-webrtc · GitHub

Have a nice day,
Fanilo

Thank you so much for solving the problem.
I just downgraded back to version 1.3.1 and now everything works fine

whitphx · January 15, 2022, 7:55am

Hi, thank you for the report.
I updated streamlit-webrtc and released a new version.
streamlit-webrtc>=0.34.1 should work with streamlit==1.4.0.

stephan · January 28, 2022, 7:40pm

we unfortunately have the same error on both 1.4 and 1.5 - maybe streamlit aggrid needs an update too? (no webrtc in our case)

riyad_parvez · January 30, 2022, 1:51pm

I’ve been using the same API to get the session UUID. What’s the alternative to get session id now?

whitphx · January 30, 2022, 5:06pm

FYI,
here is my implementation to get the session id.

Hello,

I am trying to use threads in an MQTT connection (on_connect and on_message). I was trying to use this solution to be able to use streamlit inside the threads (as seen in Live plot from a thread - #12 by hcoohb). But I get the following error:

AttributeError: module ‘streamlit’ has no attribute ‘ReportThread’

Is it due to the new version of streamlit ? I have tried downgrading it to 1.3.0 and it does not change the error

def connect_mqtt():

    KEY_CONTEXT = st.ReportThread.REPORT_CONTEXT_ATTR_NAME
    main_context = getattr(current_thread(), KEY_CONTEXT)

    def on_connect(client, userdata, flags, rc):
        thread = current_thread()
        if getattr(thread, KEY_CONTEXT, None) is None:
            setattr(thread, KEY_CONTEXT, main_context)
        if rc == 0:
            print("Connected to MQTT Broker!")
        else:
            print("Failed to connect to MQTT broker, return code %d\n", rc)

    def on_message(client, userdata, msg):
        thread = current_thread()
        if getattr(thread, KEY_CONTEXT, None) is None:
            setattr(thread, KEY_CONTEXT, main_context)
       
        st.session_state["message"] = "Save message received from MQTT broker"

        print(f"Received `{msg.payload.decode()}` from `{msg.topic}` topic")
        print("message received ", str(msg.payload.decode("utf-8")))
        print("message topic=", msg.topic)
        print("message qos=", msg.qos)
        print("message retain flag=", msg.retain)

    client = mqtt_client.Client(client_id)
    client.username_pw_set(username, password)
    client.on_connect = on_connect
    client.on_message = on_message
    client.connect(broker, port)
    return client

as the issue persists, can we reopen the issue as unsolved or do you want us to open a new thread?

randyzwitch · February 5, 2022, 3:27pm

If you are having a similar issue, I would suggest starting a new thread, as commenting on a thread that was originally solved for the first user often gets ignored (because, people see it as a solved issue).

pitanjal · February 24, 2022, 7:07am

Hey @andfanilo ,

I wanted to take up this issue as I am also facing the same challenge.

When I upgrade to streamlit 1.4.0 or 1.5.0, we get an error: No Module named “streamlit.report_thread”.

I am using streamlit-analytics and was using SessionState old code. After removing SessionState old code, streamlit-analyticss seems to pose the problem while deploying.

Currently, I reverted back to 1.3.1 and it is working fine.

andfanilo · February 24, 2022, 12:12pm

I see there’s a PR waiting on ReportThread - ModuleNotFoundError · Issue #14 · jrieke/streamlit-analytics (github.com); maybe you can ping there to get the merge done sooner than later

Fanilo

LostGoatOnHill · April 25, 2022, 7:43am

Have same issue with streamlit 1.8.1, having tried workaround by @whitphx, get report_thread not found. Any further workarounds? Thanks!

Edit: Found this suggestion by @velicanu resolved:

from streamlit.scriptrunner import add_script_run_ctx

whitphx · April 25, 2022, 8:46am

Yes the snippet I posted above was for Streamlit 1.4 at the time and not compatible with 1.8 now.

My current implementation compatible with Streamlit 1.8 is below.

            try:
                from streamlit.scriptrunner import get_script_run_ctx
            except ModuleNotFoundError:
                # streamlit < 1.8
                try:
                    from streamlit.script_run_context import get_script_run_ctx  # type: ignore
                except ModuleNotFoundError:

@whitphx We are facing the same issue when we upgraded to 1.9, we are also using streamlit analytics along with extracting sesion_state, not sure where should we make the change you suggested in your solution, could you provide some guidance

whitphx · May 24, 2022, 3:19am

@av_abhishiek streamlit_analytics should be fixed as it seems to be using the old version API.
