AWS elastic beanstalk 无法与 Librosa 一起使用 python

Question

我的应用程序在本地机器上运行正常。但是，当我将应用程序上传到 elastic beanstalk 时，librosa 库的导入破坏了应用程序。如何解决问题？

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()

我在亚马逊上使用 Python 3.8 linux 2. 使用 requirements.txt 安装软件包：

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

日志如下：

任何人都可以确认该应用程序是否适用于 EB？

Answer 1

问题可能出在 tensorflow==2.2.0。这是一个非常重的库，您无法在 t2.micro 上安装它。您至少需要 t2.medium（不在免费套餐中），它有更多 RAM 才能在 EB 上成功安装 tensorflow==2.2.0。
