Flask app build successful but failed to deploy

HezGee · April 28, 2023, 8:54am

Hello I have a python flask application which I am currently trying to deploy when I deploy the app i get a build successful message but the deploy fails. The application is an API for my machine learning project i need to deploy the app to get a live URL using render

please I need help I have been stuck for over a week.

below is MY app on github
image_2023-04-28_104542372

below is the code in my python file

from flask import Flask, request, jsonify
import pickle
import numpy as np

model = pickle.load(open(‘model1.pkl’,‘rb’))

app = Flask(name)

@app.route(‘/’)
def home():
return “Stroke Disease Prediction App”

@app.route(‘/predict’,methods=[‘POST’])

#‘cp’,‘thalach’,‘slope’,‘restecg’,‘chol’,‘trestbps’,‘fbs’,‘oldpeak’
#[0,108,1,0,250,160,1,1.5] 0
#[3,150,0,0,233,145,1,2.3] 1

def predict():
cp = request.form.get(‘cp’)
thalach = request.form.get(‘thalach’)
slope = request.form.get(‘slope’)
restecg = request.form.get(‘restecg’)
chol = request.form.get(‘chol’)
trestbps = request.form.get(‘trestbps’)
fbs = request.form.get(‘fbs’)
oldpeak = request.form.get(‘oldpeak’)

#result = {'cp':cp,'thalach':thalach,'slope':slope,'restecg':restecg,'chol':chol,'trestbps':trestbps,'fbs':fbs,'oldpeak':oldpeak}

input_query = np.array([[cp,thalach,slope,restecg,chol,trestbps,fbs,oldpeak]])

result = model.predict(input_query)[0]

return jsonify({'hearth_disease': str(result)})

if name==‘main’:
app.run(debug=True

Below is my requirements.txt

flask
numpy
scikit-learn
gunicorn

below is the error after deploying

i think its a gunicorn problem but i don’t know how to address it
your help will be highly appreciated

Hi Hez,

I see a .. at the very top of your GitHub screenshot. Is your application in the root directory of your repo?

If not, you’ll need to provide a dotted path to the module or specify a Root Directory in your services settings.

Give that a go and let me know if it helps.

Regards,

Matt

I moved everything to the root directory and it worked just fine.

thank you
