Overview

streamlit-fastapi-model-serving

Simple example of usage of streamlit and FastAPI for ML model serving described on this blogpost and PyConES 2020 video.

When developing simple APIs that serve machine learning models, it can be useful to have both a backend (with API documentation) for other applications to call and a frontend for users to experiment with the functionality.

In this example, we serve an image semantic segmentation model using FastAPI for the backend service and streamlit for the frontend service. docker-compose orchestrates the two services and allows communication between them.

To run the example in a machine running Docker and docker-compose, run:

docker-compose build
docker-compose up

To visit the FastAPI documentation of the resulting service, visit http://localhost:8000 with a web browser.
To visit the streamlit UI, visit http://localhost:8501.

Logs can be inspected via:

docker-compose logs

Deployment

To deploy the app, one option is deployment on Heroku (with Dockhero). To do so:

rename docker-compose.yml to dockhero-compose.yml
create an app (we refer to its name as <my-app>) on a Heroku account
install locally the Heroku CLI, and enable the Dockhero plugin with heroku plugins:install dockhero
add to the app the DockHero add-on (and with a plan allowing enough RAM to run the model!)
in a command line enter heroku dh:compose up -d --app <my-app> to deploy the app
to find the address of the app on the web, enter heroku dh:open --app <my-app>
to visualize the api, visit the address adding port 8000/docs, e.g. http://dockhero-<named-assigned-to-my-app>-12345.dockhero.io:8000/docs(not https)
visit the address adding :8501 to visit the streamlit interface
logs are accessible via heroku logs -p dockhero --app <my-app>

Debugging

To modify and debug the app, development in containers can be useful (and kind of fun!).

Comments

after deployment on ubuntu the Streamlit page always shows "Please Wait"

I use ubuntu virtual machine 18.04 to deploy your program.

I use following steps to finish this.

sudo apt install docker.io
sudo apt install docker-compose
systemctl start docker
git clone the project code and enter the directory
sudo docker-compose build
sudo docker-compose up

then the streamlit page always display "Please Wait", when I refresh the page, the terminal logs a problem I search for a long time but I can not resolve. Thanks for your work and waiting for your reply.

fastapi exited with code 137

Hi Davide I am unfamiliar with FastAPI, but it looks very powerful! On running docker-compose up and uploading an image via the UI I get an error:

ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))
Traceback:

File "/usr/local/lib/python3.7/site-packages/streamlit/ScriptRunner.py", line 322, in _run_script

Have confirmed api is on 8000. Possibly I need to assign more memory to the container? Cheers

Do not store a temporary file

Great article and tutorial @davidefiocco!

Just a tiny detail but I'm pretty sure you can just send the binary data from the image using https://pillow.readthedocs.io/en/latest/reference/Image.html#PIL.Image.Image.tobytes and a raw starlette.Response

Would love to read more about those subjects in the future!

streamlit exited with code 1 due to TypeError in python3.7/site-packages/google/protobuf/descriptor.py

Thanks for the example of how to tie up FastAPI and streamlit in docker.

On two of my machines streamlit exited with code 1, as mentioned in the title. The full trace is pasted below. The solution I found was to upgrade the packages in streamlit/requirements.txt to their most recent versions:

-- original requirements.txt ---

streamlit==1.9.0 
requests==2.24.0
requests-toolbelt==0.9.1

-- modified requirements.txt ---

streamlit==1.10.0 
requests==2.28.1
requests-toolbelt==0.9.1

url is hardcoded to http://fastapi:8000 but how to handle not using docker compose?
The current approach of hardcoding http://fastapi:8000 requires the use of docker compose, but how do we also handle the case that users are running the containers seperately? A situation where this occurs might be if you want to run the pytorch model on a dedicate GPU machine, and have this resource shared by multiple services (e.g.a web UI, some analytics tools). One option I used here is to pass the machine IP in via an environment variable like:

environment: - DEEPSTACK_IP=deepstack

Anyway I raise this in the hope you have an even better suggestion. It would be great to identify the optimum solutions and share this back with the community :-)

Fix issues when running streamlit

It looks like bumping up streamlit requirements may solve https://github.com/davidefiocco/streamlit-fastapi-model-serving/issues/21 as older versions may be impacted by this problem: https://stackoverflow.com/questions/61871050/filenotfounderror-errno-2-no-such-file-or-directory-sudo-sudo

Bump fastapi from 0.60.1 to 0.65.2 in /fastapi
Bumps fastapi from 0.60.1 to 0.65.2.

Release notes

Sourced from fastapi's releases.

0.65.2

Security fixes

🔒 Check Content-Type request header before assuming JSON. Initial PR #2118 by @patrickkwang.

This change fixes a CSRF security vulnerability when using cookies for authentication in path operations with JSON payloads sent by browsers.

In versions lower than 0.65.2, FastAPI would try to read the request payload as JSON even if the content-type header sent was not set to application/json or a compatible JSON media type (e.g. application/geo+json).

So, a request with a content type of text/plain containing JSON data would be accepted and the JSON data would be extracted.

But requests with content type text/plain are exempt from CORS preflights, for being considered Simple requests. So, the browser would execute them right away including cookies, and the text content could be a JSON string that would be parsed and accepted by the FastAPI application.

See CVE-2021-32677 for more details.

Streamlit requests may fail if FastAPI backend hasn't initialized yet

As the app is started with docker-compose up, the streamlit service is likely the fastest to come online (the fastapi service needs to do the PyTorch model load). If the user visits the streamlit page and fires a call, the result may be

because the fastapi service is not responding yet.

The user should just wait a bit and then results should be returned OK, but it would be better to implement some sort of healthcheck so that streamlit requests can be handled more gracefully.
