Hi @stujazan

The issue is not with Streamlit Cloud. You are attempting to deploy a Flask app rather than a Streamlit app.

You can solve the problem by deploying a Streamlit app instead.

If this is the app you’re referring to, it looks like it has successfully deployed: https://share.streamlit.io/stujazan/streamlit/main/app.py

hi @snehankekre

ok , But I deply bu stream app

And I followed these steps exactly

Deploy an app - Streamlit Docs

[snehankekre]

What app are you specifically referring to? The instructions in our docs are meant for Streamlit apps.

[stujazan]

no no @snehankekre

this url my app
https://share.streamlit.io/stujazan/heart_prediction/main/app.py

[snehankekre]

Exactly. That is a Flask app, not a Streamlit app. Therefore, it does not run on Streamlit Cloud.

[stujazan]

thank you @snehankekre

but plz can you tell my how i can create and run me app

what is steps

thank you agian

You’ve already done so yourself in the past:

stujazan/streamlit/blob/main/app.py

Use your previous Streamlit app as template, remove Flask specific commands, and replace them with Streamlit commands. You can use the following guide as a reference:

Create an app - Streamlit Docs

thaaaaaaaaaaaaaaaank you my bro …

hi @snehankekre
I did what you told me, but I got this error :
(

TypeError: Descriptors cannot not be created directly.

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.

If you cannot immediately regenerate your protos, some other possible workarounds are:

 1. Downgrade the protobuf package to 3.20.x or lower.

 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

[11:35:08] ❗️ error restarting streamlit: exit status 7: output: streamlit: ERROR (not running)
streamlit: ERROR (spawn error) ) 

How can I fix this error plz

[snehankekre]

Ah yes, sorry about that! The solution is to include protobuf~=3.19.0 in your requirements.txt file:

TypeError: Descriptors cannot not be created directly

Hi all It looks like a breaking change in one of Streamlit library’s dependencies (protobuf) is the cause of this issue. I’ve notified the team who are working on a fix. A patch to fix this issue will be included in our release next week. Until then, a temporary solution (thanks @whitphx!) is to include the following in your requirements.txt: protobuf~=3.19.0 Best, Snehan

Hi @stujazan -

I feel like you’re missing what @snehankekre is trying to tell you here. Streamlit and Flask are two different projects for serving web apps. If you are trying to deploy a Flask app on Streamlit Cloud, it isn’t going to work.

Additionally, the packages themselves aren’t designed to work together from the same Python process. You can run Flask somewhere, then call it from Streamlit, but you can’t display Streamlit widgets inside of a Flask app.

Best,
Randy
