AWS elastic beanstalk not working with Librosa python-CodePudding

My application works properly on the local machine. However, as I uploaded the application to elastic beanstalk, the import of librosa library broke the application. How to solve the issue?

import os
import pandas as pd
import librosa
import numpy as np
from sklearn.preprocessing import StandardScaler
# split training and test data
from sklearn.model_selection import train_test_split
from flask import Flask
from flask import request
from flask import Response

# EB looks for an 'application' callable by default.
application = Flask(__name__)


@application.route('/', methods=['Get'])
def homepage():
    return "Hello World"

# run the app.
if __name__ == "__main__":
    # Setting debug to True enables debug output. This line should be
    # removed before deploying a production app.
    application.debug = True
    application.run()

I am using Python 3.8 on Amazon linux 2. The packages are installed using requirements.txt :

flask==1.1.2
flask_cors==3.0.10
imageio==2.9.0
librosa==0.8.1
moviepy==1.0.3
numpy==1.19.0
pandas==1.2.3
scikit-learn==0.24.1
tensorflow==2.2.0
werkzeug==1.0.1

The log is given below:

Can anyone please confirm if the application works on EB?

CodePudding user response：

The issue is probably with tensorflow==2.2.0. This is a very heavy library and you can't install it on t2.micro. You need at least t2.medium (not in free tier) which has more RAM to successfully install tensorflow==2.2.0 on EB.
