Flask app with numpy

Serverless Framework
,
1

Hi,

I have been trying to get a Flask app using numpy running with sls.

I used the Flask template from SLS to create the app.

Added my additional dependencies to requirements.txt

which looks like following:

flask==3.0.0
markupsafe==2.1.3
numpy==1.21.0
pillow==10.1.0
pyvips==2.2.1
requests==2.31.0
werkzeug==3.0.1

I can run it locally using
sls wsgi serve

When I deploy, it successfully deploys

But when I run it shows error like following

Unable to import app.app
